Default 12GA FH(From He!!)

Got some testing done with 12GA FH we just finished, using
730 gr Dixie Terminator hard slugs..First the gun is 25 lb built on a Savage 210 action,
heavy barrel 31 in long.Stock is full of
lead shot and epoxy in the butt section..
We got 2700 fps top speed with TERMINATOR
lead slugs.No leading..All shooting done with one case to see how they hold up,over 2 dozen firings and no resizing needed on the bottom
2/3 of the case yet, only size the top 1/3 to
grip bullet..cases fall out of chamber, and I have a minimum 12 gauge chamber as it is tight fit to get regular 12ga shot shell in it.Cases are made from BMG brass that
we added rims to..John at Bridger made and put rims on.Still uses BMG primer.can also fire regular shotshells.

Loads done so far with 730 gr terminsator--

230 gr HBMG---1550 fps
280 ge HBMG---2000 fps---21k load

260 gr W860---2200 fps
300 gr W860---2400 fps---27k load

250 gr 7383---2560 fps---35k load..slight comp.

260 gr Magpro-2430 fps
300 gr Magpro-2700 fps---35k load-11,800 ft lbs.

As this crappy weather allows,
Will test 750 gr Bridger bullet; and
A Barnes 3/4 oz sabot(should get 4 grand).

Maybe we can find a way to get a thick walled reciever done to put the Savage bolt, bolt carrier, trigger etc on,with slightly larger
barrel thread..Then it would have safety margin for 50-55k loads.. The 3 lug bolt will hold if in thicker reciever...It is a real super smooth
operating action.

Rob on AR got his going also.It is built on a Borchardt falling block
action, He can run full pressures as action was for BMG case.He got
a 750 gr Bridger bullet to 3000 fps, 15000 ft lbs.Ed Hubel

Default 12 ga

Dear Ed:
This is very impressive and interesting stuff! Bear medicine, indeed! When you go on your safari to Jurassic Park, can I come too?
Small attempts at humor aside, thank you for this post!
A 12 ga., with Dixie slugs might be good to have on a trip to Alaska, (Certainly yours would be! ) so this subject has my interest. Using the Terminator, do you find an advantage or improvement in using brass cases instead of shotgun hulls? Or, would I, if using a standard shotgun? Do you think that cases made from 50 BMG would be better than brass 12 ga hulls? And then there is the question of mold selection for casting slugs.
I sure hope you continue to report on this project, cause you play with some really neat toys! Yup, I'd feel safe with you on safari!

Msorenso--Haven't got 700 HE done yet.few more
months.
Woodbutcher- brass cases are better if
you want to raise velocities a little.. You will need good sizing die.Cases made like ours from BNG are stronger than regular 12ga brass also..Our
cases could be cut back.For feeding with brass
cases in pump, auto, etc you should have a die to
crimp the mouth into groove on slug. after
loading.
Killdeer--Rob in Cal with his, maybe he can get
the guv to fire it.Ed.

Default 12 ga.

Hubel458:
Probably real easy to shoot, gun only weighs 25 lbs. Nice and comfy.
Interesting thing is the pressures you are getting. It means that higher velocities are very doable in my gun. ( mine is smaller than yours )
