12GA rifle From Hell--

[hubel458]

Tested 870gr hard slug with 7383 in 3"
plastic. Over 1500 fps in NEF short barrel.
I wish it had a longer 32" barrel..........
The folks at 50 Cal suggested we write up a
piece on the 12GA FH. Interested in what we
did to make hairy cartridge using 50 cal brass
adapted to the 12 gauge shotgun platform.
A job for Rob to do? His wild idea has been
viewed about 400,000 times in the forums
we put it in.Ed

Found another powder that works with small
primers in plastic and RMC cases, w/600gr slug.
It is IMR 4227. Ignition perfect, same load
levels and velocities as 4759.

Powders slower than shotgun type, that ignite
properly with small primers(shotgun-lg rifle);
we found 4759, VV-110, 4227, 7383 surplus,
the latter a slow powder that also works
with real heavy slugs

Pressure tested 7383 with heavy powder load.
870 gr with 128 gr of 7383-- All that could
be put in REM plastic and keep length to what
would feed from magazine of a 3" gun,
after it was roll crimped with tool in drillpress.
1513 fps-- 14700 psi. That is a slug 50%
heavier than factory Buckhammer at little
faster speed and at little less pressure.
Ignition perfect, cases fall out.
Love that $3 a lb powder.Ed

Finally able to make the
longer barrel improvement on
the 1887 12ga levergun.......
Rifled and heavy and 31"
long. After many months finally got
a barrel.Ed

With NEF. Plastic cases, roll crimped slug
in drillpress. 82gr IMR 4227 1650 fps,
with 730gr, 78 gr 4227 with 800gr, 1600.
Expansion on cases show little more pressure
as full loads of 4759 and 600gr.
Ignition perfect with small primers.
Ejects cases fine. Burns clean.
Got a GEHA bolt 12ga to put a heavier
rifled barrel on to test. Ed

[hubel458]

Tested 870 gr in NEF with our long
brass case with big primer.I have NEF
with extra hammer spring for big primer.
Got 2000 fps and still able to extract case.
Would do little more, extractor needs
to be wider and set up positive.
Used 260gr of WC-860 and MagPro.
Could use RL-22, Rl-25, Retumbo, etc.
That's 7700 ft lbs.. I get 600 gr slug to
2300 plus in NEF, long case. so you can go
light or heavy.Ed

More testing with 4227. Greg got little over 1500 fps in
3" plastic with 870 gr slug using 74-75 gr of 4227.
I did the same. This compares to much lighter
REM Buckhammer slug, we have more speed. Almost all
the way through 5 ft bundle hardwood boards.
I have Mossy 695 as well as GEHA 12 gauge
to put heavy rifled barrels on. And my 87.
Will be checking Mossy 395
for a guy who wants to put on
a heavy barrel.Here is pic of 695 bolt action
Mossberg with dinky barrel and the heavy long
rifled barrel for it. Ed

I tested in NEF 3' cases, Alliant 2400 with
small primers, Fired ok at 75 deg but when
case cooled there was majority of misfires
and squib loads. Don't reccomend it..
Here is picture of Mauser 12ga bolt action
GEHA next to a heavy barrel like I will put
on it Make a good slug gun.Ed

The 12GA From Hell, 700HE, and
700HE 3.25" is now on
Ammoguide, the last page of
cartridge list.Recent news says
H&H is going to build Paradox
Shotgun/Rifles.Ed

We tested 3.5" plastic cases in NEF, small
primers. My chamber is lengthened for our
long brass case, so they work fine.....
With 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
plastic shotgun cases.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

Damn nice qwork your doing there, and I agree with the others you should patent this asap!

[hubel458]

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

[gumpokc]

Would #3 be the....OTKLAM round?
(owwwww-that-kicks-like-a-mule)

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

[hubel458]

8ga, we gonna do a couple, first one a test
gun in an Enfield with rear locking lugs added.
All locking is in the rear, it is not exactly like
my 700HE one,as both lug seats gone in the
front like a Mauser 12ga 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 fits bore tight, for smoothbore.
The barrels I am working deal on will be smoothbore.Ed
