Wildcat 12GA From Hell

[hubel458]

The 700gr US-S slug in smoothbore, at 2000
in a 3.5" brass case, got a 2.5" 3 shot group
at 50 yds. Great slugs they have come up with
for smoothbores.
Some of us talking about getting 10 ga rifled
barrels made, here is a picture of my 4.1" long
brass 10ga I made from 50cal Russian by putting
on a rim like the 12GA FH is built.Just a prototype,
third in picture. Later I'll get RMC to make some,
as it is much easier way. First in picture is
16GA FH 3.5" long, 2nd 12GA FH 3.85" long,
3rd 10GA FH 3.1" long, 4th 8GA FH 4.3" long.Ed

!! That is some impressive firepower. As always, very interesting and informative, way beyond my skills, but well into my curiosity and interest range! Thanks for sharing Hubel, appreciate the time and efforts it takes to do so.

I now have a variety of 12GA FH test guns including
two Savage 210s in the lineup...SO I'm selling the first
12GA FH that I did on the Savage 210 bolt action.
Its in original Savage stock now, 28" Pacnor rifled barrel.
Stock is weighted and double thick recoil pad.
It is chambered for the original 3.85" long 12GA FH case.
750 plus shipping, included 4 of our long cases and
30 slugs.That is the first 12GA FH built on a Savage
and the second 12GA FH ever built. Pickup here for MI
guys ok also. Savage 210s are now 550 bucks, the heavy
rifled barrel cost me 350 bucks..Ed

[hubel458]

Matthew in Oregon got the 12GA FH Savage.
He is now in the recoil club.

Here is picture of the 12ga belted cases I made to
test a few loads in. I made it from 55cal belted
Boys case. I reduced belt diameter a little and left
the base the same, which is 12ga size.In picture
first is 55cal, second expanded to .620", third
expanded to .660"(16ga), then two 12 ga ones.
Next is our 12GA FH, and then a 12ga 3.5"
plastic case.A little work in long 12ga FH chamber
with a tool for belt step and it chambers. Ed

Here is a picture of US-S brass slug after going through
3 foot of wood slabs in a bundle. It has shed its plastic
base and it went through straight without tumbling.
This one is 570 gr fired at 2200 in RMC case, from NEF.
Also in picture is one with white sabot petals off, as it
would be in flight, before hitting target.Ed

[hubel458]

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

Keep the Updates commin, You haven even got my dad interested now.

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

[hubel458]

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. Will have pics
and info soon. Ed

[hubel458]

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

[hubel458]

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

[hubel458]

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

[hubel458]

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

[hubel458]

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

Im diggin the vintage ps1 collecting dust next to homemade hardware and ooodles of shooting and reloading information... Ahhh, reminds me of. . . . meeeee

[sosodeaf]

How to post a new thread? I want share with folks about the Sig P238 thing
and look for information on accessories such as grips or guide rods. How to post? Seems confused. Thanks for pointing me to the right direction.

[hubel458]

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

[Suicide*Ride]

Hey Ed.... have you ever thought about making any of your slugs hollow points or cut pettles on them like you see on some REM. sabots? I've been reading (w/ keen interest) this thread for the last year, & I don't ever remember seeing you doing anything other than solids. Just wondering if you've ever played w/ modified slug designs.

Btw, LOVE THIS THREAD! (& thanks for the updates!)

SR

[JLA]

Interesting inquiry SR? Got me wonderin too. How bout it Ed?

[hubel458]

We have used jacketed hollowpoints that RG Henson
makes, and anyone can get them, and they could
be segmented real easy with thin cutting wheel.
Greg Sappington on ShotgunWorld forum has made
some like that also.

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

[Suicide*Ride]

OMG! 9,000 ft lbs?!!! What kind of action? Something like Benelli (inertia) or will it use gas? (like a Rem 1100)

Quite spooky to think what might happen should the lugs shear before the slug leaves the bore. Good luck w/ the autoloader Ed...... I hope to hear everything works as engineered.

Be safe!!

[JLA]

make a video when you test fire that thing. I wanna see it work...

[focusmaniaczx3]

my god. what are you planning on shooting with that thing? i mean seriously? you could just about bring down a space shuttle with that cannon!


i want to shoot it

[JLA]

check out his you tube video focus, its IP adress is listed in one of the first few pages of this thread. its pretty neat...

[hubel458]

The loads will be mild in autoloader, with same bolt thrust
as I tested magnum 3.5" 12ga slug loads.It has a big locking
lug setup. It is a heavy built Khan from Turkey.

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 of 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. Whoopee.
Now anyone wanting any of my cases for their collection
I have a package of them all. Contact me.. ...Ed
