Another way that I put a 12ga rim on
bmg case is to use the new Magtech brass
12ga cases made by CBC in Brazil.
BPI and others sell them for less than
a buck each. Being so short they aren't
in the 12ga FH category of generating power.
But you cut them off a quarter inch long, and
turn a BMG rim down to .715 diameter, push on the
Magtech base, with JB weld in the Magteck
base, and set up a squeeze collet to
crimp the Magtech base sides into the BMG
extractor groove. Crimp it in hard and tight.
And it uses large rifle primers.Fed Mag 215 best.
Other bmg case work needed is to put a chamfer
on the bmg primer pocket and drill out the
bmg primer pocket straight so that there is no
block to the primer gases coming out through the
Magtech flash hole. Chamfer back of rim a little.
These will handle
20,000 psi loads.Ed

Here is picture of Brett Ittel's Savage 210 he has setup.
It has a 3.5" 12ga chamber in a heavy 27" Pacnor barrel,
that he put in place of original. He also put in a Knoxx
spring/cam recoil absorbing butt plate in the hollow
Savage plastic stock. He replace the plastic parts of the
absorber with aluminum parts. It is shown without the boot
so you can see how it is in the butt.He also has an oversize
pad on it. He hasn't weighted the gun with anything else and
it shoots comfortable, even off the bench with loads that get
a 500gr slug in a BPI sabot over 3000 fps. He gets this speed
with BPI and 500 gr in 3.5" plastic cases. He also can use
3.5" RMC cases and our BMG based case, cut to 3.5"...Ed

Some 8ga work.I found a way and made a die that
swages the 8ga kiln cases down to regular 8ga size.
It swages the belt down and a turning tool I made
removes the sharp edge on the belt after swaging,
to make a smooth transition to the right size.
It does it 4 times faster than previous process.
My chamber on the NEF is set up so regular sizes fit
and loaded kiln cases with the belt step won't go in.
It works with both the REM 8ga cases from BPI and the
WIN 8ga cases from Precision Reloading, and the
WIN cases are only 44 bucks a hundred, primed.
The WIN cases have the same extra powerful primer
just like the REM cases. The REM cases are black
and the WIN cases a see through plastic. Both same
thick sides.Anyone needing cases worked over
contact me... Ed

A switch barrel auto we are testing 3.5" 12ga
smoothbore USS-S slugs, with hopped up loads.
About as accurate as the other guns here. Also
I'm getting the auto set up in my 585 HE long
case.585 HE long case shown in the port.
Switching barrels only takes minutes. This 12ga
barrel about as heavy as the 210 Savage barrel.
It is originally a 3.5" 12ga autoloader I've reworked
the stroke and have a barrel extension coming to add
585 28" barrel. Gun is weighted, thick double pad.
We are going to see how mild 585 HE loads of
9,000 ft lbs work in autoloader.Ed

Holy s@#$!!!!!!!!

Guys have asked about a 10ga FH, and it is just
getting stuff to do cases with reasonable time and cost.
So a breakthrough with a 10ga FH, is putting 10 gauge
basecups from plastic cases onto 50cal Russian brass to
make a 4.05" long 10ga. I expand case using my shellholder
on original rim, put in bushing for shotgun primer, which
fires off RE17, the turn case and rim a little, and slip
on basecup with epoxy inside. Then take a 200 dollar heavy
barrel NEF 10ga, and deepen chamber like mine is.
Here is picture with one beside a 12ga FH. The 12ga FH holds
max load of about 330 gr ball powder below a slug,
and the 10ga FH holds 420gr. I'm getting things set
to get a bunch of cases to do this. Progress.
Now anyone wanting any of my cases for their collection
I have a package of them all. Contact me.. ...Ed

Here is a neat idea for a 5 shot 12ga,
a 12ga revolver. Nice looking gun.
Also I found a company that would rebore 10ga
NEF heavy barreled guns to 8ga, if they can
get 5-6 guys lined up to do it, so that they can
make tooling and charge less than
300 bucks to do it. Delta Reboring.
Let me know and we'll get arrangements made
if enough are interested.I have two now.ED

The long brass 10GA FH case shown above has a Lyman
slug in a thickwall 10ga steel shotcup that BPI sells.
That's a 12ga 525gr Lyman.Makes nice lighter slug for 10ga.
The slug has bottom chamfered to set in cup tight
and a little epoxy makes it one piece that makes it a discarding
sabot style like a SPW. That makes it front heavy so that it
is as accurate as Brenekke KOs in smoothbore. I'm
also working with a guys to cast long hollowbase 10ga slugs
like the ones Federal loads. We are figuring out molds now,
will probably make slugs about 850gr. Here is picture of
my 10GA FH NEF with long brass case started in the chamber.
Chamber is set for that 4.050" brass case and will shoot 3.5"
plastic cases also. I am going to put on a thumbhole Survivor
stock like I have on NEF 8ga we did.Ed

I LOVE the 12 gau. revolver. Did you build it? Beautiful looking piece.

No I didn't do it. It is made in Russia and
I don't think it is available here. Unless some importer can
get it listed to import, as I think it is part of the ban on
revolving shotguns coming in.Ed
