12GA Rifle From Hell

Here is picture of the original Bridger 750 gr banded solid
flat nose. 2nd is a semi-spitzer 640grI made from it, long range
capable(for vicious p-dogs). 3rd is a shortened round nose 500gr
I made from first one.And a Foster slug to compare with.
The 3rd one is mentioned in test above.Ed
 
Here is picture of a brass slug that Lefteris from
Greece is developing.It is .629 and uses sabot to take
it up to .729 12ga size. He will get a few to me to
test for speed, and due to design they also work good
in smooth bores.Ed

The hole lets air through to reduce turbulance and drag, thus giving it a better performance in flight.Hollowbase makes it work for smoothbores.Ed
 
Alot of fellows in shotgun only hunting areas are real
interested in this project, to get them better range and
power.Ed
 
Measured the sabot for the 3/4 oz Barnes
that Federal loads,and will also hold the 500 S&W bullets
out there and the lightest 505 bullets.The 3/4 oz Barnes
is .500 diameter. 505 fits pretty good also.Amazing all the stuff you can put together for our cartridge.Ed.
 
More sabot research using the 12ga 50 cal sabot that was in Barnes 3/4 oz load.The front section of a 50 bmg bore rider
bullet, it is 2nd in picture in the sabot fits sabot. It
is 470 grains, really streamlined.And
you can buy them by the ton, and just cut off the back
portion that is .510 diameter, and that leaves front part for a .500 dia bullet, a good spitzer,
1.5 inches long..Good for armor plated chucks??
First in picture is original
sabot with Barnes 3/4 oz hollowpoint slug...3rd is the 900gr 600NE slug in my sabot made
from heavy shotcup. Shot it at 2300 fps. 4th on the miniature digital scale is an older Barnes
.580 cal saboted slug expanded, it's 435gr. Ed.

Shot a 610 grain hollowpoint Dixie hard
slug into 6 gallon sealed pail of water.
Going 2800 fps, and real big hollowpoint.
First pic is pail with crimped on top.
Pail full and has filler spout capped.
Second pic,impact with water atomising,
and pail blowing apart.In the next small
fraction of a second is third after impact
with shelf cleared, the hyrostatic pressure
down, has bent top of steel frame shelf.
Same blast put jug pieces all over.
Got to get a 15 gallon one. Behind
you see my wood bundle backstop...Ed

I picked up a 12ga NEF Ultra Slug gun.24 in shorty barrel.
Added weight and thumbhole stock.
Gun weighted to 15 lbs so
far. I got 600gr hard slug to
1650-1700 so far, and shoots easy.
Got 1 1/2 inch thick pad.Working up different
loads.Should get over 2000.
Cases eject easy,no resizing needed
on bottom half of case,action opens easy,
no evidence of binding.Started case 3.2 inch,
settled on case length of 3.15-- Chamber being
full size max 12ga size expands top half of case
more than my minimum chamber in Savage does,
so little more effort needed to size.Our case, though many times stronger than regular
12ga cases is thinner at mouth, so that is
why I used tight chamber on Savage.Still
can't get used to mickey mouse short barrel.
Anyone know of a genius who could
make long alloy barrel with pivot mounted?
Cases can be 3 inches on up to
our length, and work.Ed

Yuo know, usually I read the first entry in a long thread, then skip through it and mentally block out the whinning B.S. and look for any nuggets of info that can be found.

This one has been very different. I read EVERY SINGLE WORD. This whole thing is unbeliveable, with the exception of being completely real. The work of genius.:D

I cannot put my feelings of WOWNESS into words, so I will simply say;
WELL DONE!
 
We are using NEF chamber as is for now, and just
shortened our case from 3.85 to 3.15 inches.
Case still holds 225 gr ball powder.
Nef slug gun is labeled 3 inch chamber.It could be lengthened
out with reamer to fit our full length case.Ed.
 
My understaning of the H&R/NEF slug gun is that it is the shotgun frame, and is the weakest of their various frames. They will not rebarrel it to a rifle caliber, but will rebarrel the rifle offering to a slug. If your going to do some heavy experimenting, you may want to consdier a high power centerfire, and get it rebarreled, or start with a Huntsman combo that includes a slug barrel on a rifle action.

Tom-We have checked with NEF and checked action
The Ultra slug 10-12 ga frame is investment cast like
their larger caliber rifle frames, and heat treated
to increase strength.It is SB2 action for heavier shotgun
loads. Only it has larger diameter firing
pin.It checks as hard as my Savage action.And barrel
is stronger than mild steel barrels, with hammer
forged rifling.And our strong case gripping sides of chamber
when firing holds 40% of the thrust against breech.
Paper and plastic doesn't. You can see difference in metal if you look inside the frames for regular NEF shotguns
and Ultra frame.Ed
