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 autol with long stroke I've reworked
the travel on 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
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
We talk about liking the use of heavier slug barrels
in using our slow powder giving 1/3 faster loads
in plastic cases, and handling recoil better. It is
stiffer being heavy for an aid to accuracy.
Guy out west has this heavy muzzled, Hastings, rifled
barrel, for his REM 870. In first pic is a comparison to the
original 870 barrel. It shows a muzzle as heavy as on
a NEF Ultra Slug GUN. 2nd picture is the gun itself.
That makes a neat slug gun..Ed
The heavy rifled barrel in previous post was made by
Hastings for the Remington 870. It is 26" long and a
muzzle diameter of over an inch. Hastings is gone now,
but we'd like to find some of these barrels. The Hastings
number of the barrel is 560H90.
In the meantime Remington has come out with their
SPS Super Magnum Slug Gun with 25.5" rifled barrel and
a 1" diameter muzzle, with more solid barrel, and extra
pins in mounting barrel, so a scope can be put on action. Ed
I am now putting a 3.5" 20ga on the FBW action.
We are having RMC make 3.5" brass 20ga cases. I also
bought a huge box of 3.5" plastic case Hastings
hot rod sabot slugs at their out if business auction.
Picture is of FBW with brass case in the feed trough.
Any wanting to do 20 ga brass cases, at same time,
contact RMC, they'd like to make a big batch this spring..
I also got few of the cases to make the 10ga FH
brass 4.050" long case. Anyone wanting one. I'll part
with them, but I'll only will have a few. The brass is hard
to find and costly.. Ed
I get asked about presses used for big cases.
Here is a picture of my 2 big presses on
the heavy bench, with the case spinner/lathe
on the back of the bench. Blue one is a Walnut
Hill and the green is beefed up Ammomaster.
Both are braced so I can lean on them.Bench is
braced to wall supports and benches behind.
You can see the expanders laid out on the press
brace arms, and a whole bunch of shorty dies laid
out, that fit everything from 10ga down to
my 700HE. And variety of large cases and real large
4ga-8ga dies, parts I work with. On the right is a
stack of my 585HE dies in the die boxes.Ed
Now might get real exciting load developement wise,
If we could make brass cases as long as the paper
one on the right. In picture is 3.5" 10ga plastic
case, our 10GA FH brass 4.05" case I made by putting
a 10ga basecup on 50cal Russian brass, and third
a 6" long 10ga bomb disposal case used to shoot
liquid/gel in to bomb packages, I think.
Anyone knows for sure let me know.ED
Here is picture showing surplus 50 Russian case before
and the 10ga brass case we make using it with
10ga bases pressed and epoxied on and expanding
case out straight, making the 4.050" long
10ga case.Makes a great 10ga FH.
And the case isn't weakened any, by the
process of putting on the rim.It will
stand any pressures any gun could...ED
We have put 4 different cartridges in the Savage 210
bolt guns. We added various 12ga and .700"
heavy thick barrels.
The first was our 12ga FH long case.
The second was my 700H 3.25" belted case.
Third was the 3.5" 12ga that Bret did, and
fourth is the 700NE that we wanted to see
how it works. It shoots fine, has weighted stock,
and a 27 inch barrel.Has a double thick pad.
I even have cast slugs for 700.
Cases are expensive, ones in picture are
20 bucks each...Ed
Here is picture of my Mossy 695 that has heavy barrel for
the our long 12ga cases, in fact it chambers the 12ga
belted shown in picture ok that I use for testing.
I set chamber to do belted as well as rimmed.
Second picture is some of my 585 Short HE cases, that work
great in regular length actions.We have these in Ruger,
Enfields, Mausers already. I have available supply of
brass for these of about 8-9000. Ed
