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

Thanks again, Hubel!

That is going to be one nice rig!!! Looking forward to pic of the finished firearm. Has got to be lots of work and planning!

Alot of planning, getting stuff, and building.
Here is sectioned action with parts in.
Original action that had defects
that I sectioned down the middle..I
ground out the top to allow case
to set higher, representing a
the taller action that we will
have due to larger diameter cases.
That lever in the picture is the
lever we will use with longer stroke.
Also in the action layout is the
breechblock, hammer, trigger with a
12GA FH in front, all in to check layout.
This lever looks to be easier to fit
and shape to bigger action and stock,
with a good pistolgrip to handle recoil.
Lever shape fits where trigger is better.Ed

Thanks again, and I like that lever a lot better too.

Hope have the time to get something like that going this Spring and Summer. If not I've the help and info for ideas.
Saving as always!

I will be posting more research on this thread
about other powders in 12ga plastic cases,about the
12GA FH loads, about scaled up falling blocks, my 700HE long
belted case, and the 28GA FH.Here is picture of
some other cartridges I have with some of mine.
1st= 408CT, 2nd- T-rex necked to 416- 3rd- 600OK
4th- 510HE, 5th-585HE, 6th-700H 3.25, 7th-12GA FH,
8th-700HE. Last most powerful. Ed

Got it, and saving. Thanks again!

Here is pic of the first finished model
breech block for scaleup model. You
hammer and trigger in the back of
the block. Ed

Saving, and looks like you're getting close.

Haven't had but one shooting day for over week now. Getting old what with rain, sleet, snow every hour on the hour. Know you've had probably more snow your way, but sure hope more consistent than the stuff we've been getting.

Why don't you two get a room..... Seriously, those are some cool thundersticks that you got there Mr Hubel.

Hey Dude, that is a type of project I AM going to get around to before I kick off, just for the H**l of it if anything!

The gun, not the room. LOL!

Another shotgun/rifle experiment is 28ga FH.
Rocky MTN is making me some
3.25 in 28ga cases. They are good to 38k psi.
That will get 500-550 gr out at 2500 in
bolt action.A regular 28ga gun may get to
2000, depending on how heavy barrel is.Should
average 17-1800. Just lengthen chamber.
Get a NEF Ultra cut off leaving breech section
for monoblock and have 28ga rifled barrel
made and screwed or soldered in monoblock.
And being able to hold 38k to match brass,
That would get 2500 fps loads.Ed

Got it printed out and saved. Thank you!

Here is picture of the first falling block
model of aluminum, with a roughed out
stock to see how it looks. Action is a
rough model. It shoulders nice, and
lever is inlet into pistol grip,
so you can't get banged up
fingers with the big cartridges it is designed
for, like levers that stick down at the
guard.Ed

Got it and saved here, thanks!

Like the comb on that stock also, LOL!

Here is pic of action model with lever open
and the breech block down. Also the action
will have a slot in the top rear for a
top tang of whatever length you need.
Can even add a long tang for tang sights.Ed

Here is pic of a double that I will put
barrels in, monoblock style, using the breech
section for the monoblock. This one will be
for 28GA FH. May get another same size for
my 510HE. I will be able to run full pressures
with these.....I am trying to find a bigger,
heavier one to put 12GA FH in. I want
heavier one so as to run pressures like my
Savage as a minimum.Ed.

This is some fascinating stuff! I've been doing a little shooting using an unmodified NEF Ultra in 12 Gauge, but I shoot mine with black powder (so far). Loads to date have been with a Lyman round ball (about 600 gr.), a NEI slug (about 830 gr.) and a home-made slug from a bored-out Lee 1 oz mold (about 840 gr.). I haven't chronographed my loads yet, but subjectively they are considerably faster than the loads I shoot in BPCR competition. 6 drams (about 160 gr. 2Fg) is as high as I've gotten, it is nice and accurate out to 200 meters, and it's about as much as I want to hold on to in this light a gun. As soon as I can figure out how to post pictures, I'll put a couple up.

Hmmmmm, well that didn't work. Let's try this.

yeeeeee-haw!

Incidentally, if you cast bullets for these "punkin rollers", soft lead won't work. Maybe the rifling is too shallow, but accuracy didn't begin to be reliable until I switched to air-hardened wheelweights (just drop them from the mold and let them cool). If I switch over to smokeless powder and higher velocity, I may have to start water dropping to get them harder.

With black powder, I'm able to shoot just about indefinitely with no fouling problems by loading a 1/2" fiber wad, soaked in lube (actually, a mixture of beeswax and Murphy's Oil Soap), sandwiched between two 1/8" card wads directly under the bullet. This takes up quite a bit of room in the case, of course, but seems to keep the barrel fouling from building up.

That is why I like the real hard Dixie
slugs. Takes high velocity, no leading.
Had question about locking RMC cases onto
lead slugs, as they don't crimp into the
grooves well as sharp bend works thick
mouth. First I resize tight and slightly bell
mouth.Insert slugs which take a little pressure.
Then I use a die with slightly more
taper and swage the mouth into slug, like
the fit you get with bottleneck cases.
Same deal works with our long cases made
from BMG brass.Ed
