12GA Rifle From Hell

Depends on which gun you want to put it in.
Lik if a NEF, buy a NEF 12ga Ultra slug gun,
have your smith ream chamber to 3.5",
order brass 3.5" cases from RMC, 10 for $100.
You can also shoot 3.5" plastic and get real
strong loads. plastic Cases for reloading are 17 bucks
primed for a hundred. Get a BPI catalog so you can
see what is available. Like roll crimper, different slugs,
seals wads, sabots. To double up pad I just get a
thick slip on Limbsaver at gunshop and put it over the original
pad. I add more weight to the butt using extra holes
in butt filled with weight.Ultra has one weight in
the butt from the factory. I add more.

Getting to some more 4ga/bore work.With barrel and
falling block action locked down fired off some blank
type loads to test the breach and firing pin I set up.
I fired it by hitting the back of firing pin with hammer,
as I now have get hammer and trigger setup. Firing pin
dents primers ok, breach works and headspace is ok.

For loads I have wads to take up space above powder.
Others with same 4ga case in doubles fill case about
1/6 full of Blue Dot (110gr), with 2000gr slug.

I'll use 1600 gr hollowbase slugs, with about 1/3 of a case
of IMR 4759 or 1/2 to 5/8 case of RE17, rest filled
with fiber wads.These are shotgun primer loads and I will
be using THE PRIMERS OUT OF KILN CASES at about same
price as BMG primers. And I have BMG primer cases also
that I will test also, once gun is finished in a few weeks.Ed
 
Fired 4bore with 760 gr light round ball with
fiber wads under it, using 150gr Blue Dot
and shotgun primer case. Just starting loads
for testing operation. Hardly no recoil,
like a heavy, beefed up blank load,
could go much higher with that light
of round ball. Will have pics of the muzzle
blast and the gun shooting from the side,
using heavier slugs in a week or so.
In Owen's 4bore double,that uses same case
size they use max of 110gr of Blue Dot
with 2000 gr slug. Ed

Now I know why your pictures always have a slightly reddish tint, they are blushing because you used 4bore, 760 gr ball and no recoil in the same sentence.
 
We will have a video 4bore on YT in couple weeks.
Have one therer of 12ga FH atomising 6gal pail water.
It is called Grandpa's Cannon.

Fired the 4bore with the 760 gr round ball,
using 100gr of Blue Dot under 300gr RE17,
total 400gr. Hairy load, with 3500 fps, and
20,000 ft lbs. Used the turned 4bore cases,
with shotgun primers, and with that light
projectile case doesn't need sizing. This is
good beginning bullet weight for early testing.
I am gonna do 1200gr and 1600gr holding the
speeds to give about same energy.
I won't load heavier until I get another
stock like one I have that is full width.
Also those who want 3.5" 20ga brass cases,
Rocky Mtn Cartridge is making them now.ED
 
The gun is 28 lbs, thumbhole stock and that light
of slug don't recoil much. Normal weight 16-1700gr slug
will get serious recoil.Ed
 
Tested 4bore with a double ball load of 1250 grains weight,
Used 100gr Blue Dot under 250gr of RE17, with card and
one fiber wad. 2600 fps. Recoil not bad, just brisk.
Used turned brass cases with shotgun primer, and cases
still didn't expand. Running about 23-25,000 psi.
The light ball load above about 16,000. Ed
 
Some interesting shooting with 4bore.

Double 760gr ball load of 1520 gr total, at 2300 fps.

A buck and ball load, 6 45cal lead balls, 133gr each,
and a 760 gr ball on top, 1560 gr total, at 2300 fps.

Both loads 100gr BlueDot under 225gr Re17, In the
turned brass cases, with shotgun primer.Recoil
manageable, and like a big push. The sound isn't
a boom like regular shotguns, but cracks loud
like big bore rifles,at least twice as as loud.Ed
 
I got my 20ga FH 3.5" brass cases from RMC.
The case capacity in water is 234 gr.
It holds 215 gr of dense ball powder to the
base of 490gr 20ga hard lead slugs I have.
These cases use a 209Mag shotgun primer, and
I have mouth ID set up for .620 slugs as the slugs
and sabots I have are that size. These cases will
work good out to 35,000 psi, without extreme
expansion or resizing problems. Load of slow powder
will get 490 gr to 2500 plus at 25-27,000 psi,
6800 ft lbs, using the 30" barrel I'm getting to
put on the FBW Model L falling block.Ed
 
Here is pic of the RMC brass 20ga 3.5" with
Hastings 3.5" factory plastic case loads,
and 20ga Hollywood dies. Also slugs, Dixie 490 gr,
Hastings SPW and 900gr jacketed in the one case.

Second pic is the FBW Model L setup that will have
20ga 3.5" chambered barrel in a second one. This 1st
one is in my 585HE.It is falling block in one piece
thumbhole stock, an idea I come up with on my
4bore falling block. Second Model L will be built same
in 3.5" 20ga. EDd

Transition, biggest to a smaller, in
putting falling block actions in one piece stocks.
First one was the 4bore, the big one in
picture and after it was done I got a FBW falling block
and soon figured out I could do the same with it.
It is chambered in my 585HE cartridge.
And it is pictured above with the cases.
I built the 4bore, from blocks of steel.
The FBW is the Model L, and I'm doing second one
in 3.5" 20ga, to use brass and plastic cases.
And maybe later on when I find extra 700 barrel
we'll do my long 700HE....Ed

Here is picture of FBW Model L in one piece stock,
compared to a FBW Model S in 2 piece stock.
Both are chambered in my 585HE.
These two plus the Wickcliff 76 and Ruger #1
will easily handle my 585HE with proper
weight and thick pads. These guns have
rimless extractors and my 585HE goes in and
out with least amount of metal removal from
the feed trough, with much more power.
The Model L will have a 3.5" chambered 20ga
barrel to use 3.5" MRC brass cases and
Hastings factory or reloaded plastic cases.Also
I'm working to put a Wickcliff in 1 piece stock.Ed

Here is picture of a bolt action a fella on Practical
Machinist built for an 8ga. It has 4 rear bolt lugs.
He used section of 20mm barrel for barrel.. Real nice.
Idea would do for 10 and 12ga also I think.
Has an aimpoint sight. Ed

Here is picture of the fella firing his bolt
action 8ga that he made. He uses the
super strong, heavy duty, plastic cases
like we are using in the ones we made by
boring out NEFs to 8ga.Ed

8bolt2.jpg
 
Some have asked if the guy who made above
bolt action 8ga does them for others, but he only
did one for himself, and isn't a manufacturer.

Here is picture of a cast .504" slug BPI 12ga sabot
a guy made a few for me and it has good accuracy with
our slower powder loads, with the sabot working ok.
Slug is 440 gr and hard alloy cast with decent
meplat for good penetration.But it isn't too blunt
so it has good longer range capabilities when you
get the speed behind it. Soon be the deer season and
guys are still hunting for their ideal 12ga sabot/slug
setup for loading their own.BPI is supposed to have
a new sabot this year..Ed

bpi504.jpg
 
The .504" lead slug I show for using in 12ga sabots is
one cast for using in .500" cases like my 499HE, by
sizing it after casting. Tried it at the .504" diameter and
it works in the sabot also. So it does double duty,
unsized 12ga sabot, sized and lubed in .500" use.

Some like short cases in big calibers, and have put up
various ideas. First picture is 12ga brass cases, two
2" long and other 2.25". Cases made by shortening
our cases we made by putting rims on bmg brass.
These can be used in Savage 210 and feed from mag
box. Can use 2.5" Magtech brass shortened so case
and protruding slug will be 2.7" overall and feed from
magazines of Savage & Mossy bolt guns. With 2.25" case
you can get 600gr to 1800 at least.Ed
