Home Forums Hunting & Shooting Express Rifles and Big Bores Only Been testing the 12GA From Hell--

Tested 3.5" plastic cases in NEF, small
primers. My chamber is long for our
long brass case, so they work fine.....
600 gr slug, 105 gr of IMR 4227,
got 2100. Same slug, 180 gr, 7383 surplus,
got 2100 fps. That's 5800 ft lbs from 12ga
plastic shotgun cases.Ed

Ouch, recoil in spades

Yikes.... that's 90 to 125 ft./lbs. of recoil in a 10 lbs. rifle..... and pretty quick, too (7.45 to 8.78 lbs./sec.; at 24 to 28.5 fps).

ouch.....

The NEF is 15lbs, thumbhole stock, real thick
pad. Recoil is easy. Now when we fire long brass
with 600gr at 2500 plus it gets interesting, but
the little guys here handle it ok. I can shoot
it from the hip fine. Ed

Along with testing loads in 3.5" plastic, later tested same loads
in 3" RMC brass cases; and with 600gr slug, same wt 4227 and
7383 surplus powders got same 2100 fps.I got a MEC Super Sizer
coming to size base of plastic and RMC cases. Both are hard to
resize with regular die, but this will save time and allow many
more firings of the cases.Just got 3.5" plastic for dime each,
and this sizer will allow as many firings as the RMC brass.Ed

Shoulder fired artillery

A bullet maker contacted me and he will make
750gr jacketed 12ga slugs for buck and a half.
He uses Corbin equipment, and that is a very
great price as others have quoted almost
50% more. Minimum order 500 bullets.He
has to get couple pieces of punch and die
tooling to make them .729" to fit most rifled
barrels, and he will get tooling if we pay
half, which is 300 bucks. I want to find
10 guys to put in 30 each plus order 50 or
a hundred and we have him get tooling ordered.
Contact me so I can see how many want to get
in on the deal.Then after I tally everyone
I will get back to you for the funds for dies
for you to send the them to him..Here is pic
of a sizer we got that does plastic
cases back to factory specs in few seconds
and allows 3 times more reloads. It will
also do the RMC cases I have. No more cases
sticking in dies, or spending 5 min
to get them sized only half assed.ED.

Here is the Enfield I reamed out to feed 12 gauge and BMG
size cases. I added two rear bolt locking lugs, one the huge bolt
handle and another added that locks in rear bridge. The front lugs
still contact on their top 40 %. This is concept from earlier shown
Mauser shotgun conversions, where they were made from 98
Mausers, giving a bolt action 12ga.This one is chambered for
my belted 700H 3.25" case, as a load developement test gun.
Loads up to 825 gr at 2500 so far. Ed

The three From Hell cartridges----
My 28GA FH, 2nd Our 12GA FH, can
you guess the 3rd?. What do readers think. Ed

Having so much fun we just wanted another size--
It is the 8GA From Hell, a real cartridge. 4.3 inch long
brass case. 8 ga shorter plastic case, plan on in same chamber.
The brass kiln gun case isn't as long as mine. Where do
you find the rare 8 ga brass kiln gun cases.
Looking now for guns or actions and barrels. I make it
from 20mm Suzy brass(20mm Hispano Suiza), by putting
on a 8ga size rim and reshaping like we did 12GA FH....Ed

Just looking at that 8 gauge case makes me flinch and my shoulder sore

Great post, I enjoy your work. Got me thinking about these slugs from a cartrige like yours.

I will be doing smoothbore testing later in long
heavy barrel, if I can get some I will check
them out. Ed

8ga, we gonna do a couple, first one a test
gun in an Enfield with rear locking lugs.
All locking is in the rear, it is not exactly like
my 700HE one, both lug seats gone in the
front like a Mauser shotgun.
May have a way to get barrels 'fast'---
fast being like 2 weeks, from the time I
have money to do it. And only about
150 bucks each.......Am working on it.
In pic you see long case sticking out of
the action, a couple 8ga plastic cases, a
couple of the 8ga kiln slugs, 3 oz and
hardened. Am looking for a slug built like the
Federal 10 ga one that has rounded nose and
hollow base, that will fit bores tight.
The barrels I am working deal on will be smoothbore.Ed

Howabout this Long Tom slug gun.....Ed

Hello Ed.
Take a look at this guys bullets. It is in Germany and he makes Copper alloy bullets with drive bands. Only the drive bands go into the rifling. Wouldn't that be beneficial for pressure and accuracy?? Maybe he will take part in research for the "Ultimate Bigbore"!!
Anyway, AWESOME guns you have. I have a Greener 14 1/2 Gauge Police Gun on a Martini action and reamed it out for a 12 Gauge chamber long throat. Shoots ok no excess pressure, the barrel diameter is on the LOW end for 12 Gauge.
Here is the URL for the Bullets:

The site is German and English.

Keep the Pics and Data coming, PLEASE.

Here is an Austrian Gun/Rifle Maker with a 4 Bore side by side!!!!

Northwolf--That Greener would be great with heavy
barrel. Someday I want to do one. Ok, I shot a banded
12ga slug that greg designed with 750 gr, only 3 bands,
and bottom of the grooves smaller than land diameter,
ans wa sable to shoot same velocities as hard lead slugs
with same pressure. Other banded types raised pressures
to get same speeds.Speed was 2700 in our long case
in the Savage. Ed

The only problem with the Greener Martini are LONG cases!! I have to labour to get the fired 12 Gauge case out of it. Max length would be the same as a fired 12.
The barrel is stamped 2 1/2" 1 1/16 Nitro Proofed.

I checked a Greener and if I do one
the new barrel will have a 3" chamber.
The 3" empties fed in and out ok.
They cleared the trough ok.The action is
plenty strong enough for our 15,000 psi loads,
and same pressure loads with Rem Buckhammers
factory loads in 3" plastic, as long as
barrel is heavy.Ed
