700HE & 12GA FH Capable---

4bore work. Working on design of firing pin,
and waiting for parts now. Problem is getting
real small parts without CNC for bushed
firing pin with rebound spring. But it takes
time.

We will have swaged lead slugs
in a little while as my barrel is smooth. They
will be 1600gr hollowbase, when done,
a hundred of them at least.
Got wads and cards, shown in the picture with 4bore
cases and slugs. And my 2bore case for comparison
Also 12ga wads for comparison..Ed

700HE & 12GA FH Capable---

Our cartridge work and experimenting got a nice
write up in # 470 Nov/Dec International Ammunition
Journal. Page 10-11 by Zach Weighman, a
cartridge collector and gun nut friend.

Got a guy just figured out BMG case rim, and for a rim
puts on 12ga high base cup from a plastic case. He turns
base/rim of bmg case about .008" and use JB Kwik to hold
it on. Pushes it on with press. He removes base cup with
heat gun from plastic cases,

He is using RE17, so shotgun primers will work, and he
puts bushing in case for primer. Has bushing reamed so
the primer pocket protrusion on the base cup goes up inside
tight, as he pushes on the base cup. It'll fire ok and to size it
do like I do, I push case into open top die, and push it
back out from the top with a rod and hammer. That
way the rim don't get bent up. He says it saves a lot of
time not having to make rim pieces.

We will have more info and pictures next few weeks.Ed

700HE & 12GA FH Capable---

Here is a picture of a BPI sabot with a BPI Flexseal I
use on to it in place of the original cushion seal.
I also cut shallow slots in the outside at the bottom
of the petals. Sabot opens much quicker and seems
along with BPGS seals under it to work ok without
damage, giving high velocities. In pic on left is regular
BPI sabot, behind is one I put a cushion on from a
Brenekke KO slug, and in front the one with Flexseal on.
The slug in it is one a guy casts at 440 gr and .504"
diameter, and works ok.

New info on my 499HE, from now on we will make cases
out of 450 #2 brass, as Jamisons has 3-4000 cases,
and it seems no one has the 475 #2 we used first.
Only slight case dimension change is the base .012"
smaller, all else is the same. I'm getting reamers redone
and will be able to use in couple weeks. Case will still have
plenty of taper to extract easy in singles, doubles,
falling blocks.etc.

And speaking of falling blocks I found one, and put my 585HE
in it, and it is big enough and has enough clearance to be used
for a 577NE, 600NE, long 20ga, my long 16ga FH,
the 700H, the 700HE. Cost no more than Ruger, with barrel
figured in. Will have pics
and info soon. Ed

Re: 700HE & 12GA FH Capable---

Here is picture, Falling Block I found that I put
my 585HE in. It didn't need any work on the
feed trough to feed. 585 case shown in it.
In fact the trough is big enough
and the action big enough for 600NE, 3.5" 20ga
brass, 3.5" 16ga FH brass, my 700 HE long case.
I reworked a NEF stock to it, as I'm not
a stockmaker.Nice action.2nd picture is
of the 16GA FH in the feed trough.Ed

Re: 700HE & 12GA FH Capable---

Here is picture of the FBW falling block with my
700HE long case in it.This falling block is 1.5"
wide, with a 1.125" wide breach block.
The sides are .187" thick next to breach block.
This compares to about .165" say for a Browning
B-87, Win copy. The feed trough would work with
12ga size rim if some work was done on the top
of the hammer. This has a barrel thread length of
1.005", thread diameter of 1.125" for good
strength. Ed

Re: 700HE & 12GA FH Capable---

Here is picture of the falling block with a
600NE in the feed trough. Work great
chambered as a 3.5" 20 gauge, for
20 gauge 3.5" brass and plastic cases also.

Second picture is a 12GA FH case we made by
epoxying on a 12 ga base cup onto a bmg brass
case. Turned brass down .010" and pressed on base
with epoxy in it and when set base is on good.Ed

Re: 700HE & 12GA FH Capable---

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

Re: 700HE & 12GA FH Capable---

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

Re: 700HE & 12GA FH Capable---

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

Re: 700HE & 12GA FH Capable---

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
