585 HE --- Super Strong---

If you've followed our work in the 12ga FH thread you've seen
our 585 HE cartridge and its development. We have barrels
of cases and more coming.

We have put it in all kinds of guns, and tested it with 650gr
bullet over 3000 fps as heavy load to test the brass, and also
for lighter game like deer and hogs and target fun we found
that some of the 440gr to 540gr 58cal Minie bullets work
great. Cases have same overall loaded length as 505 Gibbs.

First picture shows it beside a Gibbs.
Next pic is a barrel of cases,
Third, representative of typesof guns we have it in.Ed

Different strokes

Many guys like to stroke so to soeak, big bores..
And here is way they can do so without spending
a years pay.They can get 100 cases, die set,
and barrel to put in something for 750 bucks.
We get asked about recoil. Guns are weighted a little, thick pads,
can be ported, use moderate loads, they shoot nice...And moderate
loads still much faster than 577NE. And can be had without costing a
years pay. Most local users(only 1 in 10000 hunters go Africa) can
shoot lighter .585 Minie bullets, which load for about 95 cents each,
once you have cases... Ed

Asked about putting it in #1, on another forum.
And it is perfect case for the Ruger #1.
The very few #1s ever done in 577, they had to relieve
metal behind the action shoulders that breach block
rests against because of rim. Ours don't have to and the #1s
extractors I've seen work better with belted than big rimmed.
Ours holds more powder, cases built for extreme pressures.Ed

Case doesn't need special made shellholder, number 31 RCBS fits fine.
It is a straight belted case that holds up to 190gr of doublebase powder.
Powder need not be like charcoal, IE, really slow powder, as necked
needs. So it has effiencies of 37-39%, where necked cases are
about 29%. Here is one done in a Savage..



The loads tested at high pressures about 65,000 psi, when extracting, the
weight of the bolt after opening pulled cases out. We've fired moderate
loads in singleshots that we mono-blocked barrels into and the cases fall
out after firing. Here are couple a nice singles with 585HE in them.





Cases are made super strong, in the same factory run as the super
high pressure Cheytac cases. The base of our case is same size ahead of
belt as Cheytac/Gibbs bases. Done with same cups and draws, just uses
a different header, bunter, and sizer. Here is picture of the one we made
and the factory one sectioned showing the strong built inside corners.
These are not balloon head junk cases.



We and CH4D have die sets, Manson makes reamers, and we have some.
Reamer specs all set and the chambers made with them, the cases
extract at the highest pressures.
Here is pic of one we set with 585HE in a Greener GP.Ed

WE get asked about whether the 585HE is a DD due to being
over 50 cal, and no it is not, as we applied for and got a
sporting cartridge exemption few years ago.

First picture is base view of cases new and old. On the left is
4 new ones that come with no headstamp that I stamped,
and the 6 new ones in the middle has a 585 stamp.
We got a barrel full without stamp and guys can wildcat
them and put their own stamp on..

Second is side view with some in # 31 holders.No special
holders needed. .Notice how uniform belts are on the new
shiny ones. Dark ones are ones I made years ago.

Third is one with AP bore rider bullet in with others
behind. Maybe make a great long range target cartridge.
Got a guy setting up one with long heavy barrel for that.







Here is picture of 585HE with 700gr HP CEB bullet and 750 gr
wide meplat CEB bullet..Ed

In the pictures above you see the older first cases I made from Nyati
cases and other cases that were Nyati clones. These were straight basic,
long, untrimed cases, so I could get the longer case we wanted.

We get asked about the process of doing it and here is picture sketch
showing original case, a case with the start of a belt step, and finally
a case after it is swaged and sized. Note the belt diameter ends up the
same as the base diameter of the original brass. These cases we made
years ago was how we got the 585HE started and tested and some guns
done. This process can only work with original cases that have a thick
corner radius to leave plenty of thickness ahead of the belt. In doing this
process with different wildcats we have found cases that wouldn't work.



Now these cases have a diameter that works with regular bolt guns,
without extreme machining on the bolt, as opposed to 577NE and Trex.
Here is picture of a case held in a Ruger bolt, for example..



And our case is large enough capacity to get the power, without being an
oversize, soft case. Thicksided cases relative to size of the case are much
harder to harden the heads and the lower body back up to proper strength.
because of the extreme annealling needed, in the drawing
and heading operations in the manufacturing process.
Our cases are made with same cups and draws as the ultra high pressure
Cheytac cases, and our real high pressure tests show they perform with
no extraction problems.



Here is picture of a O/U I had top barrel sleeved with smooth tube, and use
the 585HE in it with lightweight, hollowbase Minie bullets. Shoots about as
accurate as foster slugs in a 12ga. Bottom barrel is 3.5" 12ga smooth.

Some more info- For guys in other countries you can get cases
from Bertram in Australia. I can send die sets. There is a guy
in AUS that has a reamer I sent him.

We have experimented with black powder type of loads and the
Minie bullets, The Minies we use are the ones measuring .585".
Also for reduced loads with lesser amounts of powder we found
that 24ga wads work perfect in the case, like in this picture.



WE did couple guns in smooth barrel to test hollowbase Minies.
Found that they work for shot in our case. Holds 3/4 oz of shot.
Put a 24ga card on top and glue it in.



We even got one in good ole NEF, with a 585 barrel monoblocked
into it and gun weighted, with thick pad. Guy in TX got one also
and there is video on ytube-- URL below-- Ed





www.youtube.com/watch?v=HypaUdwQGAc

We have a guy who is working toward getting the 585HE cases into
Canada, for guys there to be able to get them from him..

Our case works for black powder type of loads using .585" Minie
Bullets also. Here is picture sectioned case with 4 Pyrodex 54 cal
pellets stacked behind a 440 gr Minie Bullet.Goes over 2500.
Can be loaded with 3 pellets and 24ga cushion wad.



Here is an innovation in a 585HE Falling Block we did. It's in a
one piece thumbhole rifle stock. Nice to handle and shoots heavy
loads a comfortable as a weighted bolt action gun. FBW brand.



Here is a bunch of barrels we have, the wrapped ones are slow
twist just for guys doing 585HE guns to use Minie bullets for
deer, hogs, target, and plain ole fun Using black or smokeless.



Here is picture of one being done by a guy on a big Enfield with a
nice figured Walnut stock. It is weighted and has a thick pad.
Being done African style with thick barrel and integral front sight.
You can see a bunch cases in background shelf.--Ed

Hooray the first batch 585 barrels from McGowen has got here, more
will be built.They are the regular 1 to 20 twist barrels, and we have 14
that are profiled and polished, and 3 others that are straight blanks,
1 to 20 twist. And 6 slow twist barrel blanks for guys doing mainly
Minie bullet guns, and bunch smoothbore blanks...Pics soon.

Here are couple more pictures of the gun guy is doing with nice stock.





Here is picture of 585 FBW falling block with a Knoxx Comstock.
Helps reduce recoil in this lighter gun. Ed

Ed,

Have you built any from a good SxS shotgun? A SxS double rifle in this caliber would be a lot of fun, and useful, too! I realize that getting the barrels regulated would be a pain in the butt (and shoulder, too!) but I for one would love to have such a piece.

MARK

I got one in an O/U with top barrel 585HE,
and bottom 12ga. Put a liner in top barrel.
I don't have stuff to monoblock 585 barrels
in to a double monoblock. Be nice to have a
585HE double. Maybe some day I'll sleeve one.


Here is picture of the barrels from McGowen, with other barrels.
We got most of the McGowens profiled and some straight blanks.
Others we have are the slow twist and smooth...In back some
of the cases and die sets.



Here is picture of an Enfield and a BBK in Hogue recoil
reducing stocks. These stocks are the rubber coated with
the easy to grip, nice pistol grip..Have Mcgowen 26 inch barrels,
1 to 20 twist, barrels are heavy profile and taper
to .980 inch at the muzzle.



Here is a visual comparison of why I really like Enfields and
Rugers for big bore work. An Enfield on the left.... Lugs
built much stronger, simpler to put barrels in actions,
without the wall in the middle of front reciever. Easier
to shape breaches to feed big cases, so they don't hang up.
Left lug longer and forward, simpler to do bolt faces to hold
bigger cases...Ed

Here is picture of 585HE in a Montana Rifle Co. PH action.
The double stack mag for the 505 Gibbs they make works ok.
The Enfield in the Hogue stock above is gone.



We also had guy show us how the case can work for a
high energy subsonic cartridge. High energy for subsonic
1600 gr at 1050 fps. The 585HE Whisper
Anyone with some way overbore 14.9 mm necked
cases on huge actions, can make case inserts for
using our case to fire subsonic And fire 650gr or 750 gr at
high speeds. Can't get 14.9 Russian cases use ours in
same gun with inserts.




Break action I like we did on a CBC by mono-blocking in a 585
barrel set up especially for Minie bullets of 440 to 540 gr.

When you decide to build one of these in SxS confguration, I would be all ears! Would love to have one, maybe even the first one. Had an SKB 20 GA that would have been a wonderful donor, but just traded it to a local plumber for a bathroom re model for my wifey

Keep me posted, you HAVE do do these in a SxS someday, somehow....

Lots and lots of chopped up 'semi sporterized' 1917 Enfields laying around the gun shows, if I were to snag one, what is the cost to have you convert it to an HE? Including about 100 cases and a set of dies, of course.

I have a beautifull full custom 416 Rigby so don't really need one, but it sure would be a hoot to play with.

Ever tried these cases in a plain 12 GA SxS shotgun with a rifled choke tube at the ends of the barrels?

Others have used different 12ga loads with rifled
choke tubes with varying success. Accuracy depends
mostly on bullet construction/speed. Doubles are not
good for high speeds as our slow powder, fast slug loads need heavier barrels than what doubles have.

To have 585HE Enfield done with barrel cost, dies, 100
cases, singlestack mag, in a Hogue stock, and
the barrel, metal, chamber and stock fitting work $1300.
Without a stock(do your own) $1150. Without mag set up
as single shot $1000. The barrels are polished a little
and all fancy finish and blueing and stock
finish things others can do that have the tools.Ed

You can see from above posts I like Enfields and here is picture
of how we set up action for long case and a singlestack magazine.
We open bottom of action for length and use a lip type magazine
insert to feed cases single stack. And lips are springy so we
can load from the top.



Here is the second gun I did years ago in the 585HE, an old style
Ruger 77. And at that time I used the cases I made myself and
they work great in the gun, high pressure loads, and extracted easy.



Here is some math to show why I really like really big bores.
There is term called Average Barrel Pressure, which is the average of
all the pressures in a barrel, from the start where you have highest,
called peak pressure. to the lowest at the muzzle when bullet exits.
For high powered rifles average barrel pressure run 15-18000 psi.

There is a formula that can be used to get Average barrel pressure
fairly close if you know the muzzle energy.

We multiply ME times 12 and divide by barrel cross section x length.

Example a 458Win usually loaded to 5000 ft lbs, say in a 24" bbl.

ABP = ( 5000 ft lbs x 12) divided by (.17 sg in x 24") = 15,000 psi

Now you see there isn't a lot of room for big gains, as it would take
peak pressures damaging to brass and gun, to get say 50% increase.

Now example of 585HE in the 26" bbl we like, say a 7,000 ft lb load,
a real moderate load in this case.

ABP = (7000 ft lb x 12) divided by (.27 sg in x 26") = 12000 psi

The bigger bore allows for a much larger potential,
a 50% gain is easy to do.Ed

Here is a few of the variety of bullets we found or know about
to use in 585HE, about a third of them, from 440gr, to 750gr,
to 1200gr, to 1600gr.



Here is picture of what 200gr powder, in a case that had
the powder settled, looks like.



We now have more 585 new straight blanks giving a total of 9
basic blanks, with long ones for guys setting up target guns.
And a bunch more of the profiled barrels are being made
now to go with new ones we got left. One went on this BBK
pictured, 3 on Enfields, one on FBW, one a Ruger, two in PHs.
Guys have used 5 of the new slow twist barrels. Ed

There is a guy and his smith in AUS that has a reamer for the 585HE.
And maybe another firm there that can get a bunch reasonably priced
barrels imported in from the US. Our Mcgowen barrels are high quality,
hand lapped, and only half of what getting them in from other places cost.
Here is part of stuff that the guys have to work with..



Here is picture of the Mossy 390 action, after I'd set up for the 585HE.
Just to see how good the action is, and I have since set barrel back
and made it into a 24ga FH. Just makes an easy to work with test gun.
Being both use same size bore, and in 24ga with 3" chamber I can use
577 brass for 24ga cases, using same Minie and jacketed as 585HE.
58CAL IN ALL FORMS is where it is at, so to speak......Ed



PS-We have longer barrels now for target work including real heavy ones
of 1 5/8 inches, that some guys are working on getting bigger actions
set up to use them in. .

Here is a picture of the first 585HE to be done and firing,
in Australia, owned by the poster, tankhunter on AR forums.
Fellows there can get cases from Bertram. I can send
dies and reamers.And can get dies from CH4D.
There soon will be 3 reamers there.

And now a company starting to make 585 barrels there.
I have about 17 here, so no waiting here.

Allan and Grant Swan. in Redbank, Queensland...
allanswan at uplink.net.au.



WE have cases with plain heads if guys need some for
wlldcatting, necking down, and they can put on their
own headstamp.Ed

We've put some of the 585HE bolt guns in composite and Hogue
stocks, and they are rugged for extreme weather. And they
don't break under heavy loads. Prices are nice and they have
aluminum pillars and/or aluminum bedding blocks.
And with their hollow butts very easy to add weight to take up
recoil. If lead and epoxy added to a complete fill of the hollow,
too much weight, so I found a nice cheap substitute.
We now using rubber coated mouse balls that we have bunch of.
They are steel with rubber coating, and the right weight.
They add just the right weight and and wedge in good.
And won't rattle with coating, and we hold them in tight with
a piece of dense foam under butt pad.



We get asked about how much speed potential we have. And
we start by mentioning cases can hold 190-200 gr of ball powder
with the bullets loaded out longer. And have tested those heavy
powder loads with 650 gr jacketed bullets, in the Enfield
pictured I use as one of my test guns.



And more fun shooting, using a pistol grip on one of the
585HE falling block test guns. Real heavy loads try to spin us
around like a weathervane.. Ed

Have you necked it down to 50?

PM incoming

Safariman I answered your PM mail.

Burleyboy- Can be done and I have cases with plain heads for
guys wanting to wildcat them, If necked to 50cal be a
longer improved version of 505 Gibbs.

I need this rifle like I need a third eye, but damn the torpedo's I want one!

'''anong the fastest of its caliber''

Well this fits the bill for you, 650gr

tested over 3000 fps .. Ed

That's what I was thinking and then it would be legal for hunting in more places.

Bb

It is legal for hunting anywhere I've heard of, as we got a
sporting use exemption from ATF DD rules, and it is
registered as sporting case. Most places having real
big dangerous game prefers guys use big bores,
I think..I would think necked down for target use,
but the 750gr long pointed 585 cal bullets
are very streamlined, and would work as a 600yd or
1000yd target round in a heavy barrel gun.Ed

650 grains a 3000fps?!?!?!?!?! Holy SMOKES, those are going to leave 'a mark' at both ends!

Who makes those bullets and the lighter friendlier ones?

Do you rifles regulate well with both or Several loads?

That speed was with a soft jacket 650 gr DKT bullet.

Not made any more, as Chuck passed on years ago,

His 750 gr shot close to same point of aim at 50 yds.

The Barnes solids would go to different spot by couple inches

The Minie bullets we use go to different points of aim.

Minies are all lighter and guys GB sells them, we use ones

measuring .585" Guy here up north makes heat treated 640gr ones,

and as hard as solids, that go as fast as any jacketed and

a third the cost. And can't lead up as they are so hard.

For deer, hogs, target, minies are great, just shoot

them fast and won't lead up. Above 2700. Ed

HAve you tried the Sabot muzzleloader bullets that carry a .44 or .45 cal pointed bullet in them? I am thinking along the lines of having two scopes for a rifle, both in identical QD rings that fit on a Weaver/picatinny rail. One dialed in for a heavy DGR load, and maybe one for the Sabot load packing a relatively high BC plastic tipped 300gr 44 caliber bullet. Should be able to get some crazy-azzed speeds out of that, and the Sabot is not going to lead up a barrel, either. One MIGHT be able to even Moly Coat the Sabots! Can one just image an Elk, black bear, wild hog, Zebra or Kudu hit by a 300gr 44 caliber plain lead plastic tipped HP bullet that launched at 3400-3500fps? Maybe a Barnes MZ HP bullet in a Sabot so it holds together?

The versatility of this round is maybe one of its strongest points, especially if that experiment works too. The possibilities are legion.

Another way to go is a fixed peep regulated for the heavies, and then just one scope of moderate X's dialed in for the plains game, softer skinned animal loads.

Yes we have found two sabots, Just tested recently.

Pics of sabots and and slugs in few days,

One uses .458 slugs and other .452 pistol slugs.

A light 250gr slug can go about mach four.

Our 585 caliber is the most versatile case by far, above

458 with all the jacketed 585 bullets, with all the 585

turned solids, with all 585 lead solid and minie bullets,

with all the 585sabots avalable...I keep saying 58cal

is where it is at, time to get on the bandwagon,

they making a dozen more barrels of cases.Ed

A related case to our 585 is the 24ga FH that has 3" chamber and
brass cases reworked 577NE cases, that we reduce the rim down
to .720"... the 24ga size rim...We make minimum chamber so that 24ga
plastic cases, 2.5" long just fit. And min chamber cuts down on a lot
of brass case expansion, which the wears cases out.

The barrels are same bore barrels as our 585 and the hollowbase minie
bullets work great in it, the ones that are .585", 440gr to 540gr.
Makes hairy 24ga gun for deer, etc. Be useful in shotgun only areas.
Guys on GB sells the .585" minies. And the brass cases, we don't have
to wait for them to be made.



Here is what 585HE barrel and its monoblock look like before
screwing the barrel in.This one was 585HE, but process same if
monoblocking in 24ga FH...Ed

Here is picture of 585HE with 24ga FH ...585 longer one.
Both use same bullets/slugs, same caliber barrels.
Different easy usages, 24ga FH is an easy setup in break
actions and 585HE in bolt actions and falling blocks.



Picture of non-discarding 585/24ga sabot cup I found that holds
458 bullets and slugs tight. It had hammerhead type slug in it that
someone pulled out, and they wouldn't stay in tight after pulled.
Supposed to be for 20ga, But this sabot was a loose fit
in 20ga, though made for 20ga, so I shrunk diameter of bottom rib,
fits perfect, super tight, in 24ga and 585HE. A press in fit gives
good resistance for good ignition. real tight fit.



Here is a 24ga/585 discarding sabot that holds .452" 45cal pistol
bullets. Made by Hornady for 58cal Muzzle loaders..
With 250 gr bullet in 585HE, hopped up load will go about mach 4.



For ease of getting actions in stocks, I like composites.They are
strong. come colors, many can be painted with tough surface
paint. And They need weight added for big bore use..
An easy way to weight plastic stocks with hollow butts, use rubber
coated computer mouse balls, weight comes out perfect, without being
too heavy if using that much lead. And coating keeps them quiet, and
we hold them in with piece dense foam under butt pad....Ed

Ed,

You are using Hogue stocks for the Enfield, are these special order or what model are you modifying? I can't find any mention of a Hogue purpose built for the Enfield. If you are modifying an existing stock is it a pillar bed or bedding block stock?
Thanks
Thaine

Thaine- I use the stock they make for Howa 1500/WEA Vanguard.

It is pillar bedded and I rework inside of rear pillar to

align rear screw, open mag area for longer case, etc.Ed

First AUS buffalo killed by 585HE. By Tankunter with his Ruger #1.

If you use closeup on picture, you see loaded round on the buffs hide

next to the 585HE Ruger #1.... A nice heavy barreled gun..Ed




I put the 585 in a Savage 112, lots of room lengthwise, figuring out an
extractor is a problem, but then got a look at the savage 212, the 12 ga
one with big diameter bolt and locking lugs. Its locking lugs are bigger
than the lugs in a big PH bolt action. So one day will do one
on a Savage 212, and adjusting extractor to fit no problem...Ed

Here is picture of 100 cases loaded with CEB solid nose bullets
and hollowpoints. This bullet is a turned solid with wide meplat
or wide hollowpoint. .



Here is pic of a Enfield with a jeweled and polished bolt, going
to be 585HE. In the back, Bolt jeweling and polishing done by the
great craftsmen, Bob Snapp, years ago.



Picture comparing unfired and fired cases showing our tough cases
One on the left fired with 650gr at 2400 and base above belt
didn't hardly expand, Size the top and reload/shoot again.
And AHC will make guns now with our 585HE for any wanting
super top quality guns.They have some cases to give to guys
as a sample to show guys the case. Ed

Ed, do you change the bolt handles on the actions, or does someone do it for you. I might want to get rid of the dogleg on mine, but could do it afterwards.

Pretty cool stuff!

Mike

Ready-- thankyou..

Biebs-- No I can't change dandles, don't have tools and
experience for that. Most that I do is cut them and
straighten and weld up. a real amature job

Yes changing handles csn be done by an experienced smith.ED

Ok I did find a way to change to straight sporty handle
on Enfields, which is to cut them off before the dogleg
bend an inch away from the bolt body, then I'm able to weld
ona nice handle extension I found.

Our 585 caliber is modern bolt action continuance of the 577 Nitro
Express rimmed case, that many big game hunters like. Usually
set up in double rifles. It has an interesting history, from the old 24ga
size to 577NE, to the 585 Nyati with the picture of Ross Seyfreid
shooting one in a Ruger #1 under recoil knocking his shooting glasses
off, to the Trex of internet fame knocking guys over,
to our 585HE the strongest yet.

The 577NE is an offshoot of the 24 gauge caliber, only they went
eventially to brass cases. Back in the 1860-70s, starting first with short
cases and black powder, cases built like shotgun cases, called the
577 Snider, then going to coiled brass cases, still with black powder,
then on to drawn brass cases, called 577 BP Express. then to 3"
and other longer cases with smokeless. The Snider started out with a bullet
of .570" diameter and through the progression to the 577NE bullet
diameter ended up at .585". This general bore diameter of cartridge guns
and muzzle loaders, it is really interesting on how they developed
and were used by military and then hunters over the years. The Snider
was necked down to make the 577-450 , a military round used all
over the British Empire, by the tens of millions.

Bases of both 24ga and 577NE are about the same. Now we have made a
24ga FH, a slight regression to earlier times, by taking 577NE brass, and
reducing rim diameter to 24ga specs. Two minute job. And
stamp the caseheads 24 ga.

For shotgun upgrading in power and range, It is all about increasing
the power in easy to find brass cases, stronger actions, and finding
reasonable price rifled barrels. Same barrels we found for 585, work for 24ga.
The 577NE brass we make 24ga drawn cases from, for example are
about a third the cost of 600NE brass, or getting turned 24ga cases made.
We could use 24ga thin cases but they are a pain, expand way too much,
with slug loads which makes resizing without crumpling cases a problem.

Info about the power in types of guns normally set up with 24ga FH,
break actions, bolt shotguns,etc. In thin brass 24ga case, 440gr slug
goes 1500, with about 2000 ft lbs, that's in a 2.5" Magtech brass case.
Now using the better, heavier 3" brass we got, we can increase speed
to 1750 fps increasing energy 50%, going to 2000 fps about doubles
energy. And going to 2300 which good brass holds ok, in heavy barrel
gun, gets us near 2 1/2 times the energy. About 37-40,000 psi which the
actions hold in this smaller diameter case, compared to 12 gauge size.
So makes relatively smaller bore shotgun, 24ga, with 458WIN power.
.Perfect with Minie bullets. Perfect for deer and hogs, bear, etc.

Great for slug hunting in shotgun only areas. We mark barrels 24ga
and cases 24. A decent case that is complimentary to our 585HE....Ed

Here is a different look at 585 sabots holding 458cal bullets.
Sabots hold leafd as well as jacketed.



Here is a long turned streamlined bullet in our 585.




Anyone wanting to import barrels, actions, cases, etc into Canada from
here can work through Prophet River Firearms in Lloydminster, AB.

The here being the US, as well as our group with barrels, dies, cases,
and McGowen with .585 barrels in stock, CH4D with 585HE dies
in stock, gunshops with # 31 shellholders.
And later few retail outlets setup with cases in stock... . Ed

Another application for our 585 HE is for guys with the 14.5mm
PTRDs, to use our case with chamber insert. In many places 14.5
cases are scarce, real expensive, as well as most 14.5mm cases
being steel are not the easiest to resize/reload. Our case sizes
like regular cases and can be easily reloaded many times.

And in a PTRD with almost a 5 foot long barrel can get 650gr
spitzer bullet to the same speed the 14.5mm gets a 900 gr using
3 times as much powder. 3300 fps. Or get a 900gr at 2800.
Great possibilities for fun shooting. And tactical use in a place
where it would be useful to reload in the operations field, where
steel cases are scarce. A 100 cases do over 2000 reloads.



I like Enfields to put our 585HEs in, for reasonable cost guns. .
Here is inexpensive way to fancy up the Enfield Bolt handle by
cutting the dogleg part of the old handle off and welding on
inexpensive contoured handles I found, one of which is like
Ruger 77 handle, one on the right . Something even a novice
like me can do.....



A lot of guys are crazy about CEB bullets. Here are light 450gr
ones in our 24ga FH. The hollowpoint can range in weight 450gr
to 700gr.. The 24ga FH is nice complement to our
585HE for the shotgun only deer hunters... Ed

For lightweight plinking, deer hunting, etc, in 585HE as well as 24ga FH
here is picture of 58cal Hornady sabot that holds .451/.452" light
bullets 225 to 300 gr. A way to shoot targets economically. Low recoil
but a big bang and satisfaction. That sabot is one made for ML, but
with .452" bullet in it is a real tight fit in brass cases, to stay
in place and give good ignition. A 250 gr bullet would go about
mach 4 with a top load..



Here is what 585 bull barrel, target blank looks like, 1 5/8" OD and 32" long.
It'll go in heavy action of some kind. 4th one from the left. The one in yellow
sleave on top, is a heavy contoured one with muzzle of .980" ..The 5th, 6th,
7th blanks on bottom are straight 1.375" 585 regular twist blanks.
One in paper wrapper is slow twist 585 barrel...Ed

Here is picture, nice cast bullet I like for the 585HE and 24ga FH.
It is .585" diameter and 650 gr and these particular ones are a
hard lead alloy, plus they've been heatreated. They are about as
hard as copper jacketed softs. These have a flat base, and
fairly streamlined..



But to penetrate good and do great damage to game or target they
can be soft lead and hollowbase like Minie Bullets. Here is picture
of timber drilled through with .585 soft lead Minie from 585HE.
Picture is the back of 6x6 timbers where Minie bullets came out. Ed

In Canada there are 3 guys there now setting up 585HEs,
and one setting up 24ga FH. Another friend setting up a 585HE
handed out a bunch of cases and info sheets at the SCI convention.
We are getting some more reamers made. Some more dies sent
here. Another pallet load of cases coming.

Here is picture of a light spitzer bullet in the 24ga FH case,
will work in 585 also. Good for hunting and medium range
target work.



Here is picture of 585HE we did in the FBW with regular two
piece stock.We put a tenon on the forearm to wedge into the
front of the action below the barrel and a tight barrel band
on the front. Ed

Here is comparison of our 585HE and Trex case, and while
we have barrels of cases and more coming and many available
in stock in AUS, many are finding Trex cases scarce...



Here is picture of a neat falling block that could work for our
585HE with little work, the Wickcliff.




Here is picture of the singlestack mag box we built for Enfields
fitted to the bottom of BBK action.Very little changing and
it fits a lot of different actions, as a fixed magazine, with its
own feed lips,and we load from the top.Ed

Here is picture of a 585HE we did in a Mauser 98 as a
singleshot test gun. We used a composite stock we
adapted to fit action. Weighted to 12 lbs.



And speaking of singleshots a fellow in the Yukon is
just finishing up one in a Ruger #1.

Here is one reason to like 585 calibers is bullet varieties,
this picture is only about half the bullets and slugs
we know of, and most can easily found. Ed

There is couple 585 videos on Swann Gunsmithing's Facebook site;

Of our 585HE in first Ruger #1, that was done in Australia, set up

for the poster Tankhunter on the AR big bore forums. That gun killed

the first buffalo that I posted picture of above. You can go

direct to the page and click on the videos to watch the test firings..

Here is picture our 585HE in a Montana PH action in a MPI stock, with the

style of a CZ stock, that a guy is setting up. The stock will be finished brown

and metal finished with a Gun Kote finish...Ed

One of the first of modern 585 caliber wildcats, since WW2, the 575 Miller Greiss Magnum,
was first in records in the fifties, It was made from BMG brass shortened to 2.70" long
and necked up from 50 cal to .585" with what looks li\ke a little sharper shoulder..

They rebated the rim quite a ways to .618" to maybe fit 98 Mauser bolt.Used a special action.
Listed as a shooting 750gr bullet about 2400 fps. It holds about 150gr of ball powder under
a 750 gr bullet, maybe little less than 3" 50cal spotter case, where our 585HE holds
180gr under a 750gr'.

We made one for experimenting on a full length BMG case.With rim left same as the base
and would need a BMG sized bolt and action. I'm glad to be a big bore wildcatter,
and happy to be in the company of big bore nuts, old and new. Years ago when
guys did big wildcats they took what was available, to rework, and maybe
they could have used the 3" spotter case if they could have found couple barrels full.

But it takes a lot of work to reform cases that much, with the multiple dies,
multiple annealings and case trimming and extreme reworking of regular rifle actions,
which is why I like our cases, simple and straight, any regular long bolt action,
falling block, break action, etc, the 585 good for dozen or more heavy loadings,
moderate loads, last forever..

In making our 585HE we made it a size, a new belted size, to fit regular size guns,
not BMG actions,that didn't have to be used from a tripod, and could be put in a favorite,
the Ruger #1, other falling blocks, without taking metal out of the feed trough.
And to get the same and much more powder space like a cut back,
real short, fat, BMG wildcatted cases to 585, we made longer case and worked
with a group buy to get a factory run. We thank gun nuts for the help.

Here is picture from the great site, cartridgecollector dot net, of the M&G Mag .Ed

Probably first 375 caliber cartridge made from 585HE necked down, the 375 Warlord.

Guy did a real nice job, with what looks similiar to a Weatherby style shoulder.

Kinda outdoes Weatherby & Cheytac. We have cases with no headstamps for wildcatters.

First picture I got sent me today off of facebook and this one is from the great sniperforums.





Another fellow is planning on shortening the 585HE to maybe 2.4", for use Marlins and Henrys,

and other leverguns, redoing their 45-70s. With the belt they will have good headspace control.

Without a rim that takes up circular space, say like our 24ga FH, a 585 bore, but which is perfect

with a rim for break actions like our 24ga FH in a Magtech...Ed

Sorry to be away so long. Health and money problems.
Here is how the top of the singlestack magazine looks that we
made to use in Enfields and other bolt actions. The lips that hold the
cases are springy, and we can load it from the top. The inside of action
below feed rails are relieved a little and that allows feed lips to
move and work ok.



Here are couple 24ga FHs break actions, a CBC with monoblocked
585 barrel in it, and a guys NEF he had a 585 barrel monoblocked in.
The 585 barrels are perfect fit for 24ga, and 585 Minie Bullets
are a perfect for barrel and 24ga case fit.






Another matter---It seems strange for me to ask for help when
I ask guys on the net for help at times. . But I really am in a bind.

That is truth, Our small income disappeared from our farms truck
garden business, as my my knees are shot and can't hardly
walk, I can't do field work, etc. And the wife's lung condition
got so bad she can't work.. So we finally had to quit that,
but were and are in debt. We need little extra money to try
to keep our health fixed up and pay bunch of back bills and utilities.
As well as needed for traveling to doctors, treatments,drugs, etc.

Could you all maybe get together with others on these forums
and kinda take up a collection to help get me out of my troubles and
debt. Like 10 or so bucks each put into our paypal account as gifts.
And if you want to mail it, contact me to get you
my mailing address.

The Paypal email is jegunownerstv.com

Best Regards- Ed

PS-- I really need help. Not astronomical amounts, but fairly fast.
Just a little from each to help. A quick boost so to speak.
We never made anything on the 12ga FH, etc, work and research.
The little coming from sale of 585 brass, dies, barrels,etc,
goes to pay to the places, where rest of the money
is owed, for getting them made..Ed

Another action we found/researched that isn't priced 3 grand

or more that will work great for our 585HE is the

Stiller bolt action that is made for Cheytac based

cases. Less than 1200 dollars. Compares in size

to the Montana PH actions( four of them) we

have put the 585 in.Ed

Here is picture of 375 Warlord next to our 585 case he made it from.
He is going to make couple later necked down to 416, and 458.
There is another guy working on doing one necked down to 357 wildcat.



Here is a picture of our poster Biebs on AR, 585 HE, in a MPI stock.
He used a big Enfield action, with a fancy jeweled bolt.



We found couple other big actions for our 585, that can even feed really
long overall length loaded cases, like 4.5" long or more, if you are
using long pointed bullets for real long range target and hunting work.
One is Lawton 8000 Cheytac action, and the other is Stiller Cheytac actions
made similiar, justa newer version. Both actions come in 1.45" diameter
and a 1.60" diameter recievers.

And Vestals Gunsmithing in Virginia does great work, decent prices, has
these actions and will build you fancy 585 HEs. .. He has, working with
another guys mag box setup, setup an extra long, good working, single
stack, center feed, magazine..He has our 585 HE reamer on hand, we have
barrels, cases, and reloading dies..Ed

Here is couple different setups our guys checking for our 585HE
in a long, Lawton Cheytac action. First laminated thumbhole stock.
Second in a Hogue Compstock. The action can mount a scope rail
like shown on the table in 1st picture or a receiver sight in 2nd picture.
The scope rail is a piccatiny,. if you need long range work.





The stocks used were wide ones for REM long actions, just add recoil
block ahead of recoil inleting for the longer action, drill new screw hole
Open the stock forward to original bolt hole for longer cases and mag.

About Enfields for our case, one of my favorites, Some don't like the
sporterizing, welding bottom metal straight. Many think straightening
is a huge job needing special jigs, etc, Not really, just use one for a jig
with a bolt, to weld on the straight extension, Do top weld, then cut old
extension that is under off with a thin cutting wheel, then weld bottom.
When we bolt the short piece on the one we are straightening, we grind
the short slant off so the added piece lays on there flat.
The one you cut off can be used as the top extension for the next one!!!
Just keep on building...Ed

Here is picture of another neat sporterizing deal for Enfields.
On those without rear bridge pocket welded up, we just mill down
and shape it so debth of the pocket matches bottom section of
weaver rail and screw or epoxy it in. Shape to drive in hole tight.
Can use as a rear scope ring mount or mount for peep sight
like a compact UTG sight...



If we have a welded up Enfield rear bridge, then we can use sight
like on this gun a guy is doing. Has a rosewood laminate stock.
He will have it checkered, sanded, with fancy finish.



Here is a fancy stocked 24ga FH built on a NEF, built by
a guy in Canada. Its straight back, high comb
stock, handles recoil great... Ed




More about 585 BB short case for lever guns, pistols,AR Uppers,
Work in 71s, later 1886s, Henry steel frames made for 45-70.
One guy is putting one in single shot action set up with
Contender style pistol grip for testing in long rifle barrel,
to simulate pistol recoil..Be very brisk recoil in a case
that holds 110 gr powder under a light Minie bullet
Maybe work in a Rossi Judge with heavy barrel.
Or rolling block rifles and pistols....Ed

Here is a picture from the back, of a big Lawton action that
our 585HE fits in nice. Scope rail on there is tapered
for long range shooting.



Here is what our wildcatter buddy is making from our
585HE brass to see how they look and experiment with.
He is getting reamers, dies, and gun setup first for the 375.





In some ways big bore shotguns and rifles are sexy.
By looking at the shape of the fire and smoke cloud....
Thanks for picture, to the great NitroExpress Forums site. Ed

A poster reading our threads said '' I'm slowly becoming a recoilapheliac''..
That is neat term , and very glad that folks are catching the big bore fever.

Here is a simple, yet neat peep sight we can use on the rear sporterized
bridges of Enfields, works on other rear bridges also.Including shotguns.
I like peep sights the best for most shooting. They also come with flat
bottoms also for bridges and receivers that are flat on top.



Another picture of the 585 HE one of our guys put in the MPI stock..





On straight sided cases like our 585 HE the die set has a mouth expander
die to make it easy to insert bullets. The die flares the mouth, but I always
felt that doing what is really a relative relatively sharp flare, and then the slight
roll crimping the same area of the case into a groove on the
bullet or slug, shortens case life.

So I just use expander plug out of the die, by hand, using just the bottom of
of the expander plug and just push it in a little, wobble it around a small
amount, bullet goes in ok, case mouths last longer, good for dozens of loads,
with moderate hunting and target loads.Only takes a few seconds and less
work that has to be done in the press ... Ed

Here is picture of a hard plastic molded shotgun case, holding
a slug, without crimping, a company is experimenting with.
This one with light slug supposed to do over 2000 fps.




Here is video by Corlanes Sporting, Dawson Creek, BC, CAN.
Known as, Rocky Mtn Rifles, video on Youtube of them testing our
585 HE in a barreled action, they are building for a guy. They are
shooting it into their big bullet trap with test load..

https://www.youtube.com/watch?v=1vzQjRGfT1A

Allan and Grant Swan in Australia are building 585HE for a guy,
the second they built. First one killed the buff pictured earlier .
AHR and Vestals will make folks here in US a 585 HE.
Here is another view of a Lawton action big enough for 585HE..




Here is picture of Rossi SS with 585 barrel mono-blocked into it,
chambered for our 585 BB 2.17" case, to do testing in a light rifle
with just pistol grip to simulate the case in pistols. Others going to
put case in leverguns, autoloaders. We got plenty of cases Ed

The style of most break actions singles aren't the greatest, that we
we used for 12ga FH, 10ga FH, other caliber barrels we mono-blocked
in them like .585" bore for 585HE and 24ga FH.. One that is close
that we have, is the Magtech.

Well the guys have found one that is super strong lockup and looks
real nice. And has the good quality look. It comes 12ga light shot barrel,
soon be monoblocked to rifled 24ga FH, the little brother of the 585HE.

We told company if they did them with NEF style, rifled, heavy slug barrel,
for shotgun caliber only hunters, they couldn't make them fast enough.




Here is picture of 585HE, In an Enfield that Bret and Darrel in Minn
set up with great camo finish, with nice brake job. It is in a Hogue, recoil
reducing, rubber coated, Compstock.Great job they did.. Ed



Here is picture from the rear of the Enfield we mounted the short Weaver
rail piece on. It is mounted in the sight pocket that the actions have;
Can hold scope ring or a rear peep sight like UTG makes.. Ed

Here is folder shotgun, the guys set up as 24ga FH.
Shoots nice, looks nice, it a more expensive break action,
compared to many others.




Here is another view of what we feel is a nearly perfect
break action. Guy is making a strong 24ga FH with it.




Here is picture of a 585HE MRC PH a guy set up..




Here is picture of our shorter 585 BB for leverguns, etc, with
variety of bullets..Can get energy like regular elephant guns..Ed

Here is a Midland break action a guy is doing in 24ga FH.



Here is old catalog picture of different stuff used in old days
for shotgun loads. Some would be hairy in brass cases



Here is picture of a MN a guy is doing 585HE in..
It is singleshot. Redid bolt handle mounted it on the bolt
further bac, so the port could be lengthened for our long case.
Needs polishing and blueing, scope rail added.



Here is another picture of the PH 585HE with great looking stock.
Nice looking wood. Ed

Here is pic of Big Lawton action bolt with

our 585HE case in it.Ed

There are guys on Castboolits forum experimenting with
locking on plastic bases securely on slugs.
Making their own front heavy ones for smoothbores.

Here is picture of our 585BB case next to long 585HE.




Here is another view of the great camo job on the
585HE Enfield, a top view. Ed

Here is picture of a 585HE made on a Stiller bolt action for guy in Canada.

It was made for the poster Spooksar on Africa Hunting and Accuratereloading,

by Corlanes/Rocky Mountain rifles, in Dawson Creek BC Canada, with a

Stiller action, Timney trigger. the stock is a blue/grey laminate. He imported

the barrel, cases, dies, etc.. from us, through Prophet River in Lloydminster AB.






That action similar to Lawton we had and neighbor got, that won the King Of The

2 Mile shoot at Whittington, with the 375 Lethal cartridge the neighbor made,

from our 585 brass. Made it full length case,.. It is big one on the right.

He made an 18 lb gun with McMillan target stock, a huge scope, tripod..

Nice thing is we don't need BMG action.






Here is picture of a case a Trex owner made using our 585 brass, by putting

a piece of 11/16 tubing ,cut a piece 2/10 of an inch long with a tube cutter chamfered

the cut side a bit and tapped it on the case down to the belt with the brass pipe

and fireformed it in the T Rex chamber.......Made a perfect fitting case.

Cut our brass to 3" to fit shorter trex specs. He was out of brass

and couldn't find more, so he invented his own. And our rim was big

enough so his extractor still worked ok....His original Trex case base is .685"

and our rim and belt on first case run, is .655" diameter, and base ahead

of the belt on unfired cases .631" and the brass sleave pushed up tight to the

belt just takes up that little difference. Ed.

Some more on wildcat 375 Lethal.......

.375 Lethal Precision Arms LLC rifle shooting prototype solid 400gr Berger bullets.

Mitchell built this rifle himself using a McMillan A5 Super Mag stock, Rock Creek barrel,

Nightforce ATACR MOA scope, Phoenix Precision Bipod, and a Lethal Precision Arms

muzzle brake. Lawton Action. Lethal Precision his own gunsmith shop, will make

these target rifles for anyone into target shooting and long range hunting..


Remarkably, Mitchell nailed first- and second- shot hits at the 2477-yard target,

a full 1.4 miles away. It is windy out there, makes shooting hard with a time limit.

The prototype 400 grain Berger Bullets solid was superb, (G7 BC of 0.56 at 3000 fps).






Here is 585 HE in an Enfield, in a Choate Heavy Varmint Stock. These are super strong.

The butts of these can easily be weighted. Couple guys doing them....... Ed

Here is a picture of the 12ga FH brass case that Nathan

Vale had Bertrams make. Next to short plastic case.




Here is a picture of our 585BB headstamp. Perfect lettering

for our case as it came from production line,.




I like Hogue stocks, but they aren't made for singleshots.

We use singleshots for our 12ga FH and 585HE.

Here is picture of a NEF we set up for 24ga FH and we adapted

a Hogue 1300 Winchester Hogue to it. Looks a lot better, and

handles recoil easier than factory, Butt hollow, easy to add weight,





Here is picture of 585 case in the Lawton bolt, and the wildcat

375s and others made from our cases, work in bolt also. Ed

Our friend Brian from the far north went to Africa with his 24ga FH he did in
a NEF break action and got 3 nice buffs with it. Good job.


Our 585HE, 700HE and the great 12ga FH are now in the new COTW book
published in Oct, now out for sale,




We now have our target 375 HE cartridge, made by necking down our 585 HE.
The others couldn't make enough 375s, so we started our own. Got a bunch
guys doing it, most into the 2 mile shooting venues, We're making cases,
testing, reamer prints at reamer guys, we are getting guys going. The 2 mile
shoot last year really got the interest booming for 375 necked from our case,

Here's how, size and seat 375 HE, one simple die, a 1" die, no huge dies needed
A die we can make with resize reamer from reamer guy, a regular die body,then
pass on to the next guy, one reamer can make whole bunch of dies for folks.

I do primer work separate, not in the press. SO First with lock ring set, I size cases.

When coming back out of dies with case, we notice the case still well centered,
held straight, when it is down as far as the length of the 375 HE neck... IE
the sides and shoulder corner still supported tight.

So we put washer or another lock ring on, same thickness as neck length,
below original lock ring, screw down tight tight in press,

Dies had a 5/8 x 24 thread in top, had powder fill bushing and other stuff same thread,
reamed out from bottom to set bullet height, with ram, case,and bullet up,

After priming, loading in the powder charge, we carefully start(boat tail makes it easy)
bullet in case by hand, slide up in die, into holder, raise ram to to top, bullet seated
perfect. Die can have different thread in top as long as big enough to hold seating
bushing of some kind , that can be made from many items.

These target bullets held in by strong neck tension, no crimping needed, and notice
bullet point will get no marks or dents, fast, easy, no 380-500 buck special dies.
Bushing centering bullet on ogive is very accurate.

OVER 900 375HE cases piled behind presses getting done. About 600 on another
bench nearly ready. Small batches in shelves.And we will do more.

All 375 info, prints, specs, pictures, load data, etc, is public domain, worldwide,
for any target, hunting, etc, use..Ed

Here is picture of one of 3 buffs our guy from Canada got in

Africa with our 24ga FH he did on a NEF, in 2nd picture








Here is the neck die setup, with insert stems/plugs for the top that

are set in .020" steps to make our 375 HEs shown behind

from our 585HE cases. 900 cases behind and 600 on

another bench, mostly done, and 600 started elsewhere,

We also made a hydraulic form die, 375 HE test gun, starting with

lighter bullets, for example got 340 gr to 3700,

Will test up to 400gr We will find top speeds and powders needed

to get that, and have info where to get powders. Reamer prints are

at reamer guys, all prints and info is public domain... Ed

Picture of fellows at Vestals Gunsmithing test firing 585 HE

they built for a guy. They got 750 gr to almost 2800 from

ultra short barrel, not a full load . A regular barrel would be

over 2900, 14000 ft lbs with full load..





Picture of our 375 HE cases, with little 378 WEA on left.

Middle case is with 330 gr, right case is 400gr bullet.




Here is picture of out 375HE testgun, in heavy t-hole stock.

So far 340 gr to 3700 and 360gr 3600.




Next 416 HE target case, these run through the hydro-die,

test gun done,will complete testing soon, to confirm specs.

When specs set, info will be sent to reamer guys

Soon will have 408 HE with specs set up also, for guys,

Smaller case 416s and 408s can be reamed out for

our bigger case .Ed

Here is the before and after of 375 HE cases
necked, 2 on left, and then formed in hydro die... Ed




Here is pic of 416 HSM second from left we are experimenting
with, going to see if we can make the ultimate 416 ELR case.
Can be 3.60" to 4.00" long, a long one pictured.
Holds over 280 gr ball powder under bullet. The
3.6" case can hold about 250gr under bullet.. In picture,
1st case is 416 HE, 2nd 416 HSM, 3rd 375 He, 4th 378 WEA.

416 HSM will get 400gr to 4100 plus without needing BMG action,
470 gr 3800 plus , it may be the ultimate target, singleshot 416..
Case will work in fat bolt actions, with heavy enough barrel
to have good, milder, barrel harmonics and be under 50 lbs.
A lot of the 2 mile type shoots are adopting 50lb limit.



Here is picture of the 416 HSM fireformed once,
next to bmg case we make it from and as we
improve wildcatting process next few weeks
some specs may make small changes, now from
base to shoulder is 3.45", case 3.97" long. Ed..





Manson has 416 HE and 408 HE prints, as well as 375 HE
He can also make you a resize die reamer from that info.
We got 700 cases in 416 and one more pass if 408s wanted, ,
Going to do lot more cases for these 2 sizes,
PM or email. ph 989-644-5228..

Here are final specs for 416 HE.
Length 3.32", belt diameter ,655", base dia .635" ,
length base to to shoulder 2.860" , 30 deg shoulder.Ed

Guys asking about strong economical bolt gun to use for 28ga and
410 ga and 32ga with brass cases and higher pressures than plastic cases.
They can use a MN bolt action, here is pic of one with
our 585 case in the action.Guys can get Magtech brass cases or have
RMC make them....Guys can make 32ga case from 500 NE,
410s from 9.3 x 74 brass, etc..



Here is picture of our 416 HSM case sectioned next to original
BMG case on the right sectioned, to show that we still have
enough thickness in the sides to handle high pressure,
in a case with 310 gr capacity..We are getting the wildcatting
work set up so we can do at least hundred a month.
We have lots of 585s, 375HEs, 416 HEs, 408 HEs.....
And working toward getting 416 HSMs in big numbers.



Here's comparison of 416 target cases, 1st 416 HE, have whole bunch.
Second is model of what I'd have made on medium machine, if I could,
the 416 HE Long. It has capacity of 230gr..
Third is our 416 HSM which we are working on making by wildcatting bmg
cases, And if had run long cases, make longer 375 HE necking down 416 ..




Bryan Litz just recently shot 3 shot group at 2 miles using Paul
Phillips heavy barreled, target rifle built by Lethal Precision in
375 Lethal Mag(585HE necked down, very similiar to 375HE )...
It grouped 17.5 inches tall by 22 inches wide.

Applied Ballistics shooter Mitch Fitzpatrick just hit 3 of 5 at 3520 yards,
weekend 10-13th at Valdina Ranch , west of San Antonio.
Also used the 375 LM case similar to our 375 HE
Great shooting at the 2017 World's Longest Shot Challenge. Ed

The 12ga FH case now is in the new COTW book on
last page in the wildcat section, I think page 324.
They gave good credit to Rob for the idea of that case....


The model 416 HE long case in middle, hydro formed one,

has case capacity of 240 gr, and the 416 HSM in picture,

on the right, we fired a case twice, capacity is 320gr.. Ed..




Shooters talking more now; short, fat cases sticking, pockets not lasting as expected.
Trying to get best speeds the things raising pressures are bad case proportions, too fast of
powders, and the debth of the bullet into the powder space, as shown in the picture below..
My 375, 416, etc testing, bullets loaded like bottom one, in longer freebore....Ed.

Here is case measurements for our 416 HE target case
made from our 585 HE big belted case. Ed

Here is recap simple setup to get faster loads with 12ga sabots

& slugs, Example using break actions...., reaming chamber

in a 12ga break action to 3.5" with a 3.5" 12ga reamer, that isn't

something needing special order, and use 3.5" plastic cases , or

get 3.5" brass cases made. With mag shotgun primers and

our slower powder loads you can get a quarter more speed,

which gives 50% more energy...
