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

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!

You should invite ARNOLD over for a little offhand shoot.

What about the 700 Hubel. I am really wanting one!!!!! Please tell me its available.

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.

Did more testing, Got a 3/4 oz sabot up\to 3900
fps, got a 750 gr solid Bridger banded slug
out ar 2520.Ed.

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 )

WB--Yes it makes us feel good.We get better than
700NE power in a Savage for less than 600 bucks.
Here is pic of the gun...Ed

WB--When I chrono I have a stand up bench and heavy
tripod that I lock barrel into. so total wt
is about 100 lbs.Off hand I've fired it a few times with heavy loads.Ed.

Gentlemen, please excuse me, I didn't mean to do that 3 times.
Mr. Hubel458, you do most impressive work!

You know how sometimes you think... wow, that is rediculous, then you realize, that somehow, this is necessary advancement of technology. Truly amazing.

msorenso is going to make a 700NE on
a savage. It is great to see others
get big bore fever..here is more info on our 12GA
FH cases,in picture is 3 different bullets
in cases, and original bmg case with rim
turned off and threaded for the 12ga size
rims shown in picture.Ed.

hubel458 · « **Reply #21 on:** February 27, 2006, 01:21:55 PM »

Here is picture of the case we fired 36 times,
sectioned to show no thinning or stretching.
No thinning that can even be measured.Ed

Ed,

Here is a comparison picture of big bores, ones
to be used in place of bmg which may not be
big enough, in answer to the other thread about
bmg. 1st 700NE- 2nd 12GA Fh- 3rd 700HE..Ed

hubel458 · « **Reply #24 on:** April 01, 2006, 09:08:48 AM »

Here is comparison picture of our case and regular brass case, both sectioned showing how much
heavier and stronger ours is, Ours in pic is the one we fired 36 times.Ed

hubel458 · « **Reply #25 on:** April 17, 2006, 06:24:01 PM »

Anyone wanting a case or two to look at or
collect, let me know. Have some extras.
Ten bucks for case, trip to PO, and
postage.Ed.

msorenso · « **Reply #26 on:** April 18, 2006, 03:30:09 PM »

Just curious what cal does the 12 fh calculate to be?

hubel458 · « **Reply #27 on:** April 18, 2006, 05:36:07 PM »

matt-Our barrels are .729 caliber.Ed

hubel458 · « **Reply #28 on:** May 27, 2006, 04:54:48 PM »

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 inch 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
