12ga,10ga,8ga,4ga FH;585HE/700HE, other Big Bores--

I'm visiting here to talk about the 12ga From Hell and
other developements it has led to.Nice site you folks have.
I'm with a group of experimenters passing on the years of
info and pictures to all gun nuts around the net, about
12ga From Hell and other big bores. We have posted some
round the net about our many ideas we have implemented for
12ga,10ga,8ga,4ga,28ga,20ga,16ga, and my 585HE/700HE wildcats.

The idea for the 12ga FH, and the first gun built for it,
was Rob Garnicks on the AR Forums. In the first picture,
a heavy duty Borchardt falling block. He has gotten
1000 gr to 3000 fps in this, a high pressure action.

Then I and others joined in and set up a big variety
of guns for the case. The case, a brass case 3.85" long,
made from BMG brass expanded out with straight sides,
to take 12ga .729" dia slugs and a 12ga size rim added on.
Also we get turned brass cases from Rocky Mtn Cart of that
length and shorter. Many guys used 3.5" cases, as standard
reamers are available, and 12ga 3.5" guns are available,
so that they could shoot 3.5" plastic also. Our 3.85" chamber
and 3.5" will shoot any of the shorter cases.
In our work we found ways to get over a third more velocity
in shorter plastic and brass cases using slower powders
than regular fast shotgun powders. We reloaded fast
rifle powder, IMR 4759, IMR 4227, in larger amounts
and got 600gr hard lead slugs over 1800 fps in 24" barrels,
and were lab tested to be at or under magnum shotgun
pressures that are used in factory 3.5" loads.


More pictures, the 2nd showing long brass 12ga FH case with
regular 12ga case. Other 12ga FH guns are next,3rd Nef Ultra
heavy barrel with length added, 4th Nef 8ga made by boring
out heavy barrel 10ga, 5th FBW falling block,my 585HE belted
case.The FBW has a 20ga 3.5" extra barrel also.
.And we also worked with 8ga,4ga, in falling blocks, 20ga,16ga
in break actions, and my wildcat 585HE,700HE in various actions.

6th picture is our big cartridges from 2 bore on down, in
order-2bore- 4ga- 8ga- 10ga- 12ga FH- 700HE--700H 3.25- 30-06..
7th picture is 4bore falling block we built on our design.
Our 4bore is 1 inch bore.We also helped in getting the barrel
threads larger in the new large MRC PH bolt action to fit our
cases like the 700H 3.25" shown in 8th picture in MRC.

9th picture is an 8bore bolt gun a guy on another forum built
from scratch.Last is Savage 210 that Bret in MN set up with
heavy barrel and a recoil reducer put into the hollow stock.
Shown with boot off so you can see the build. He has gotten
saboted 500gr slugs over 3000 in this.We will post a bunch
more info and we welcome your ideas and help. And we'll give
all the help we can to folks ..Ed Hubel

None that we know of. We make guns little heavier
with double thick pads, and porting. My
really big ones, thumbhole stocks which
drop recoil about a quarter.Ed

Well those are definitely the biggest shouldered-to-fire calibers that I've ever seen. Guess that's the point, eh?....lol.

More history of firsts, in our 12ga FH and big bore work.

The first gun of mine to have this case was
my Savage 210 in first picture with a regular style
heavy stock. Later changed to thumbhole stock.
I changed barrel to heavy bull barrel and
chambered it for the 12ga FH 3.85" long case.

Second picture is the first NEF 12ga Ultra that we put
the first 12ga fH case in. I only had to lengthen chamber.
The same gun now has long barrel and thumbhole stock.

Third picture is first NEF 10ga heavy barrel that we put
the 10ga FH in. Gun came with long 30" heavy barrel.

Fourth picture is the first 8ga test gun we built using the
super strong 8ga kiln cases with the belt step swaged
down. It is an Enfield that we reamed out to take the
case, like the 12ga Mauser 12ga conversions were done.
And we added extra rear bolt lugs for strength.

Fifth picture is the 1st gun my 585HE was put in.
It is an Enfield and gets 750gr bullet 2700 fps.












And in the vein of old time gun actions, of which are various falling
blocks, we like them also for the hairy big bores, like the 8bore and
4bore ones we made over the years, that are pictured above.
Following are 3 pictures of various parts and processes of making the
action, using easy to get small parts, lever, trigger, hammer, etc,
and the action block, breach block from steel blocks in 1st pic.

Last 2 pictures are the FBW brand falling blocks, one which is the
Model L that we adapted to the one piece stock and the other is the
smaller Model S with regular two piece stock. Both are set up with
my 585HE. I can run full pressure in the 585.

The Model L, I can switch to a 20ga barrel, 600NE barrel,
and my 700HE using moderate loads. Last pic is Model L with
thumb hole stock, and my 585HE case in the action..Ed

What kind of accuracy are you getting at different ranges with these beasts?
