Here is picture of the 12ga wad column using two
BPI BPGS seals, Flexseal,cork, and sabot. Bret in
MN has, in a long heavy rifled barreled Savage
like mine, gotten 28-3000 fps with a 500 gr XTP bullet
in the sabot with a 3.5" plastic case. And it extracts
ok with the Savage bolt action extractor.
He is using slow shotgun powder, Alliant Steel.I can't
get that high in my NEF 12GA FH and make the
extractor work with the Alliant Steel powder loads.
The NEF handles pressures fine, just doesn't extract
like a bolt action Savage 210. Using RE17 without cork,
I get 28-2900, with max of much slower RE17 with 420gr
slug in the sabot, in NEF The case shown was fired with the
RE17 load like that....Ed

Here is picture of NEF I've set up with my
700H 3.25" belted case to show the versatility
of NEFs and my 700. The 700 cal barrel monoblocked
like I did the 585HE. I put monblocked barrel on
the same SB2 frame that I have my 12GA FH on as
it has the beefed up firing pin for big primers
use in our 12GA FH case and in my 700H case.
Other projects coming.I found a heavy 16ga barrel
to monoblock in one to test the 16GA FH cartridge
I made. It is the 3.5" brass case mentioned
earlier in the thread.
Also a bunch of us are going to take 500 S&W
NEFs and put my 499 HE case in them, with just a
chamber job. It is a case that will get the zip
in 500gr slugs. NEFs are great guns to experiment
with and along with reasonable costs, we don't
have to worry about case length. Ed

Got single stack mag figured out for 12GA FH and
my 700H 3.25 in PH. I fit a bolt action 12ga
box mag and its follower and spring
inside the PH mag box. Easy to fit in metal box,
and permanently mounted to metal and floorplate.
Holds 2 down. That way feed lips already a working
design. And opened back of 12ga box for longer case
like I did with my 700 in Savage 210. Also work
for anyone doing a PH in 12ga FH if they aren't
loaded too long or with 3.5" RMC cases. Using most
cast 12ga bullets like Dixies, the overall length with
3.5 brass is 3.9" and fits 4.05" box ok. Here is picture
PH from bottom showing its big size.You can see in pic
there still is room to make box longer yet.
And the feed port can be longer.Montana Rifle has
great action here with lots off room and strength.Ed

Ed that box mag sounds interesting! I still haven't sent my Ultra barrel to Rob to get it reamed - just too busy with everything else right now to pay attention. The public range opens back up in September, and I am really wanting to pop off some rounds then.

I got barrel on the 4ga/bore falling block gun.
Barrel 32" long, 1.87" breech, gun is 27 lbs.
Notice breech block is down and huge hole in barrel.
Maybe shoulder cannon is the right term for it.
It is all inleted into thumbhole laminated Vulcan
50 cal stock, of which I need more, if anyone
knows where there are any. 4 bore cases shown,
next to the gun, 2 with 2000gr slugs,
and I'll use a big ammomaster press for them..Ed

Here is a picture of the front end of the 4bore,
showing a 2000gr slug protuding out. Simulating
stop action photo work, as if anyone wwould be brave
enough to put a camera out in front of it
when it fired. Will have it firing by fall.
I plan on using hollowbase lead slugs of
about 1600gr, as it is a smoothbore. Ed
