12GA From Hell in a break action--

[Dilinger23]

HOLLY CRAP..!!!! YOU SHOOT ANYTHING WITH THAT WILL EXPLODE FOR SURE ...KABOOM SHOLD BE ITS NAME...

[hubel458]

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

Had a light barrel 87 12ga replica now
it is this Long Tom slug gun.....Ed

[hubel458]

Got an 8ga barrel blank being made now,
will be here end of the week.Found this
info on plastic 8ga kiln gun loads, they
load a frangible 710gr slug at 2300-
for 8300ft lbs, load 1275gr hard slug to
1700, 8100 ft lbs. We will outdo those easy
with our non-shotgun powder loads, in
a heavy barrel. We setup an Enfield for 8ga.
In the 87 long barreled gun we will be testing
Breneke slugs. Guys are reporting good accuracy
in smooth and rifled barrels. The pictured barrel
on 87 is smooth and we will see how the
slugs in pic stand some speed.Ed

[hubel458]

Tested 35" smooth barrel in 1887. Got couple
1 oz foster slugs over 2400, with 110gr
of 4227. 3" plastic case, regular primers.
This is a heavy barrel for that type of load,
don't do this in your 12ga skinny barrels.
The 28GA FH cases on the way.Chambering
bolt gun for it now..Ed

[hubel458]

In the 87 long smooth barrel got
1 oz Brenneke to 2400 with 110gr
of 4227, You could use 4759 and
VV110 also at lesser amounts.
Barrel is cylinder bore size.
Brenneke slugs need no wads as the
locked on wad works good.Ed
And going heavier in 87 got 600 grain
Dixie over 2000, got a Buckhammer slug
I took out of factory load over 1900.
Buckhammer and locked on wad is 630
gr. Tested in 3" plastic cases.

The firing pin on the 87 didn't protude out
like I like them to as it comes from factory,
so I removed .015 from the hammer stop.
It fires big and small primers perfect.Ed

10GA FH..a NEF 10ga, medium to heavy wt smooth barrel.
28" long, gun weighted to 14lbs. Factory FED 765gr loads
are 1300 fps. 200 gr of first powder tested is 7383 surplus
and the regular shotgun primers got 765 gr to 1600,
for 4300 ft lbs. Case won't hold anymore 7383.
Federal factory hollowbase slug is .025" smaller than
10ga bore. I bumped it up to the .775" size, by expanding
hollow base. With 7383 that gave another 150 fps.Fast starting
shotgun powders expand base better than much slower 7383.
The Federal factory load has 120gr of wads/seals about 1.4"
long. Better to replace with much more slower powder,
getting better velocity, still at low shotgun pressures.Ed
We will test 4227 with the same slug , and saboted slug
of some design. We roll crimped with crimper in drill press.
Case expansion with 7383 very little(.006") like
the factory loads. 3.5" plastic.Used one .050 wad.Ed

just what I need for my 10ga shotgun, looking foward to the load tested with 4227.

[hubel458]

In 10GA NEF 110gr 4227 got 765gr slug
to 1800, ejected ok. If it was a really
heavy barrel it could do more.
Starting load 90gr. In Using the
7383 surplus at 150 gr, don't even have
to resize to fire 3 times. The 28GA FH
done and testing in next couple weeks.Ed

[hubel458]

Fired 28GA FH-- Cases extract easy.--It is
in bolt action Enfield. With 550gr jkt slug,
full load 150 gr of WC-860, got 1900 fps.
This will be slowest load and powder.
In picture is 3.25" brass 28ga cases, regular
28ga plastic case, jkt slugs, a 458Win
for comparison.Regular cases work also.Ed

[hubel458]

28ga cases are made by Rocky Mtn Cartridge,
Barrel is rifled with 4 grooves, 1-22 twist.
You could do one on Savage 210.Another
shotgun bolt action that would handle it
with little work, heavy barrel, is the
395-495-595-695 bolt action Mossberg.
Just to show that 28GA FH isn't puny, here is
picture of it next to a 505 Gibbs.Ed

[hubel458]

Here is picture and info on Royal
Arms' site for hopped up 12ga loads,
used in little cannons for bomb work.
Anyone got any of these fired that I could inspect to see how they are built.ED

I like the Savage 210 so I'm putting
a 700 barrel on one and chambering for
my 700H 3.25 case. Working on it now.
It is a straight belted case, .700 cal.
Should get the same energy levels as
the 12GA From Hell case in same action.
In pic is 700H case in the action.
There is guy building a 600 Nitro
in 210 also. Ed

28GA FH research. Guy on forums suggested using 54cal
rifled barrels for 28ga as they are easy to get. I looked into
it and did some testing. It is ok as long as you keep bullet
about 400gr as most 54cal barrels are not super alloy.
You got to use the thick heavy ones also, being stronger.
And everyone with 28ga wants slugs and there is no slug loads
from factory, and to reload the heavier bullets we shouldn't use
these barrels or regular 28ga barrels with 600-700 gr slugs.
But there are couple dozen 54cal bullets out there
stocked all over the gunstore shelves, in weights from 300 to
450 gr. There are heavier but for 28GA FH on deer 400gr is
great. I tested the 405 gr copper plated Powerbelt brand, with
velocities from 2300 to 2800 plus fps. That's 6500 ft lbs.
The 54cal slugs load tight in the RMC 3.25" 28ga case fine by
sizing top a little tighter. Bullet obturates to fit .550 bore
as bullet is hitting target straight. A lot of 54cal barrels
go from 530 to 560. 54cal slugs range from .534 to .560"
There are different sizes of 28ga barrels and chokes,
so some where there is lighter 54cal slug that fits..
And with light slugs the pressure limits with the MRC brass
match top muzzle loading pressures, so these barrels will work.
And great thing is the 54cal barrel guys ain't allergic
to making long barrels. I've shot one MRC case 15 times and
still going strong...Ed
