Wildcat 12GA From Hell.--
I just got a super shotgun done,that shoots the real
fast sabots I mentioned in the sabot thread below..
We used a Savage 210 bolt action with heavy barrel and
stock.Brass cases are real long and we made them by putting
12ga size rims on BMG brass and straightening cases.Here is
picture of our case next to regular 12ga plastic.And our
chamber will also fire thw regular shells.Ed

Shotgun calibers are exempt from the
over 50 cal DD rules as per--
Title 18 GCA, Section 921.
The other over 50 cal cartridges like my
585HE and 700HE we got a sporting use
exemption by applying to ATF, as per the
same Section 921. Older over 50cal
like 577NE are grandfathered in.Ed0 -
Some interesting shooting with 4bore.
Double 760gr ball load of 1520 gr total, at 2300 fps.
A buck and ball load, 6 45cal lead balls, 133gr each,
and a 760 gr ball on top, 1560 gr total, at 2300 fps.
Both loads 100gr BlueDot under 225gr Re17, In the
turned brass cases, with shotgun primer.Recoil
manageable, and like a big push. The sound isn't
a boom like regular shotguns, but cracks loud
like big bore rifles,at least twice as as loud.Ed0 -

I got my 20ga FH 3.5" brass cases from RMC.
The case capacity in water is 234 gr.
It holds 215 gr of dense ball powder to the
base of 490gr 20ga hard lead slugs I have.
These cases use a 209Mag shotgun primer, and
I have mouth ID set up for .620 slugs as the slugs
and sabots I have are that size. These cases will
work good out to 35,000 psi, without extreme
expansion or resizing problems. Load of slow powder
will get 490 gr to 2500 plus at 25-27,000 psi,
6800 ft lbs, using the 30" barrel I'm getting to
put on the FBW Model L falling block.
! also have a case of the 3.5" factory Hastings
SPW, locked on sabot, loaded rounds to use.Ed0 -

Here is pic of the RMC brass 20ga 3.5" with
Hastings 3.5" factory plastic case loads,
and 20ga Hollywood dies. Also slugs, Dixie 490 gr,
Hastings SPW and 900gr jacketed in the one case.
Second pic is the FBW Model L setup that will have
20ga 3.5" chambered barrel in a second one. This 1st
one is in my 585HE.It is falling block in one piece
thumbhole stock, an idea I come up with on my
4bore falling block. Second Model L will be built same
in 3.5" 20ga. EDd0 -
Transition, biggest to a smaller, in
putting falling block actions in one piece stocks.
First one was the 4bore, the big one in
picture and after it was done I got a FBW falling block
and soon figured out I could do the same with it.
It is chambered in my 585HE cartridge.
And it is pictured above with the cases.
I built the 4bore, from blocks of steel.
The FBW is the Model L, and I'm doing second one
in 3.5" 20ga, to use brass and plastic cases.
And maybe later on when I find extra 700 barrel
we'll do my long 700HE in FBW....Ed0 -
Here is picture of FBW Model L in one piece stock,
compared to a FBW Model S in 2 piece stock.
Both are chambered in my 585HE.
These two plus the Wickcliff 76 and Ruger #1
will easily handle my 585HE with proper
weight and thick pads. These guns have
rimless extractors and my 585HE goes in and
out with least amount of metal removal from
the feed trough, with much more power.
The Model L will have a 3.5" chambered 20ga
barrel to use 3.5" MRC brass cases and
Hastings factory or reloaded plastic cases.Also
I'm working to put a Wickcliff in 1 piece stock.Ed0 -
Here is picture of a bolt action a fella on Practical
Machinist built for an 8ga. 4 rear bolt lugs.Singleshot.
He used section of 20mm barrel for barrel.. Real nice.
Idea would do for 10 and 12ga also I think.
Has an aimpoint sight. Ed0 -
Do you get powder by the truckload? 0 -
Here is picture of the fella firing his bolt
action 8ga that he made. He uses the
super strong, heavy duty, plastic cases
like we are using in the ones we made by
boring out NEFs to 8ga.Ed0 -
i need one of these that will be strong enoff to handle the 8 gauge industrial round in al rem an win loadings any makers or takers out there for this job grady_mitchell2002@yahoo.com ////??????????? 0 -
Some have asked if the guy who made above
bolt action 8ga does them for others, no he only
did one for himself, and isn't a manufacturer.
Here is picture of a cast .504" slug BPI 12ga sabot
a guy made a few for me and it has good accuracy with
our slower powder loads, with the sabot working ok.
Slug is 440 gr and hard alloy cast with decent
meplat for good penetration.But it isn't too blunt
so it has good longer range capabilities when you
get the speed behind it. Soon be the deer season and
guys are still hunting for their ideal 12ga sabot/slug
setup for loading their own.BPI is supposed to have
a new sabot this year..Ed0 -
well ed who does ????????? 0 -
The .504" lead slug I show for using in 12ga sabots is
one cast for using in .500" cases like my 499HE, by
sizing it after casting. Tried it at the .504" diameter and
it works in the sabot also. So it does double duty,
unsized 12ga sabot, sized and lubed in .500" use.
Some like short cases in big calibers, and have put up
various ideas. First picture is 12ga brass cases, two
2" long and other 2.25". Cases made by shortening
our cases we made by putting rims on bmg brass.
These can be used in Savage 210 and feed from mag
box. Can use 2.5" Magtech brass shortened so case
and protruding slug will be 2.7" overall and feed from
magazines of Savage & Mossy bolt guns. With 2.25" case
you can get 600gr to 1800 at least.Ed0 -
Have had a bunch of different guys shooting
the 4bore with light 11,000 ft lb loads.
All say it is a tremendous thrill.
Simply the greatest shooting ever.
So many have opinions on what is a real big bore.
I think really big starts at .585........
So in that vein I have made the 585 Hubel
Super Magnum, 585 HSE, giving a nod to necked
cases.Also can make the 620 HSE for 600 guys.
This is my only wildcat base case with a neck.
Base and rim are .750", shoulder is .720".
and case is 3.7" long. Power in the range of
14,000 to 17,000 ft lbs. Can be used single shot
in the PH, the Savage 210, the Enfield. Not for
mass production by me, cases too hard to make.
An experiment with necked cases.
Picture of the case later.Ed0 -
20 gauge-- Fired factory 3.5" plastic cased Hastings 395 gr
locked on sabot slug in 20ga with 30 inch barrel and
got 1900 plus fps. Same sabot slug in RMC 3.5" brass case
with shotgun primer, got 2500 fps. Case bases didn't
expand. Load of 150gr RE17 slow enough getting to
peak pressures is easy on cases. Dies work with
both case types.Ed0 -
Some more 20ga- 490gr slug in RMC 3.5" brass case
with shotgun primer, got 2400+ fps. Cases very slight
base expansion. About .001" above base.
Load of 180gr RE17, shotgun primer.Ed
Got asked about the Taylor KO factor, some of our
cases.Max loads for my guns/cases combos.Ed
4bore in my falling block-- 1600gr at 2500 - 571 KO
700HE in my bolt gun
1000gr at 3200- 457 KO
12GA FH in my Savage----1000gr at 2500- 357 KO
585HE in my bolt gun
750gr at 2800-- 300 KO
577 trex comparison
750gr at 2600--278 KO
700NE comparison
1000gr at 2000- 295 KO0 -
20ga testing- 600gr slug in RMC 3.5" brass case
with shotgun primer, 2300 fps. Very slight
case expansion above base.
Another load style- 12 number 1 buckshot,
about 510 gr worth, 2000. Glued a 20ga
card in the brass case over the shot.
Few more guys coming, having fun
shooting the 4bore this summer. Ed0 -
There are fellas who have and are planning on
doing hopped up loads and cases in the Greener GP,
Martini type action. Here is picture of one done couple
years ago by Aussie guy on NitroExpress forums. They
need heavy barrel in place of original. It has a rifled
Pacnor barrel and weighs about 9 lbs. In my measuring an
action here, they will feed a 3" brass case with a protruding
slug, like the cast Dixie or the Henson jkt slugs.
I like the looks of these old classic guns. And they are
strong enough with 3" RMC brass to get 730gr slug to
2000 fps...Ed0 -
A fella cast me some 10 and 8ga hard alloy lead slugs.
10 ga 1050 gr, 8ga 1320gr, fullbore, have large concave
in the base. Should need little more hollow in the base
for longer range accuracy. Just hard alloy, not heat
treated. Nice design, one wide groove, for lube if needed.
Fired one in NEF 8ga below, with heavy 3.3" plastic kiln case,
1700 fps, 9000 ft lbs energy. Entered backstop straight
at 40 ft.Have pics of the new slugs soon.
The new blue BPI 12ga sabots are out now.Ed0 -
Comparison of slug type and speed for accuracy.
Comparing better 12ga slugs for rifled and smooth.
The US-S 570gr slug, with
locked on base does 2-3" groups at 50 yds
and about 9" at 100yds in heavy barrel.
At 2000 fps in smooth bore.
Now a Dixie 600gr slug in rifled barrel at 1300,
2-3" at 50yds- about 9" at 100yds;
BUT Dixie at 2000 2-3" at 50 yds and 6" at 100 yds.
It seems that slower slugs in rifled barrels losing velocity
gets below the speed of sound at 100 yds which
affects accuracy. Of course super heavy bullets, like
12-1500gr, make it harder to start out fast
enough to be supsonic at longer ranges.
This accounts for the guys info I posted earlier about his
high speed in rifled 20ga killing deer at 160 yds.
And holding tighter groups at longer ranges.
He kept velocity above the speed of sound
further down range......Ed0 -
About slugs going from supersonic to subsonic.I understand
it is that blunt bullets that are in most shotgun slug/sabot loads,
do not maintain best accuracy when passing back under the speed
of sound like spire point bullets do.Speed of sound about 1150 fps.
Now on, FED 239 primer in 8bore and the 4bore cases I have
with shotgun primers. They almost as strong, from my primer tests
as the kiln primers from WIN and REM.And they seem to dent easier
in my 8ga testing than FED209 or the REM kiln ones. I get them from
the 3.5" 10 and 12ga Fed primed magnum cases. Makes ignition surer.
Lotta guys want to try Magtech 2.5" 12ga cases. Well they are
stronger built than any of the old time brass cases I have seen.
About dollar each, go in same chamber as plastic, same strength.
The rifle looking cartridge in a slug gun is what some like..
If you have break action load them with protruding slugs any length.
If auto or pump in 3.5" chamber load them up to 3.1" overall
with protruding slug and you can feed from magazine.
RCBS has sizing dies. Loaded that length about the same power
as a 3.5" plastic case roll crimped on same slug, magnum load.
Don't leave air space in Magtech, but use wads and seals
like in plastic cases..Ed0 -
I found some 4bore plastic cases, 4 inches long, red
colored, looking like an oversize 12ga Activ case, They are all
plastic without a steel insert in the base like Activ cases
have. No markings. I understand they are Fiocchi.
They are the size for the 4bores that are about
.950 inch bore. They are suitable for shot loads of moderate
pressures. Guys loading them say they stretch out after
a few loads. And they use about 3 oz shot.
I will test them with a light buckshot loads
of nine 45cal buckshot, 140 grains each.
Total 1260gr, a little less than three ounces.
In picture are plastic cases with brass ones and 3.3" 8ga.
The base of case will be shimmed with strong wide tape to
fit our chamber, cutting down on the stretching.Ed0 -
When I made the 16ga FH, shown earlier in this thread,
I had couple bmg cases that were partly worked down, and not
yet expanded to 16ga mouth size. With a rim on it bigger than the
base which was .770". Well, I've had guys ask if I would ever
have bottlenecked cartridge. This led me to a way to do one.
I made rim .770, left shoulder diameter, swage case sides straight,
and expanded neck for 585" size. Cut the case to 3.7" length, and
we have 585 Hubel Super Magnum, HSM. This will be my only
bottle necked wildcat. I can make the mag box on the MRC PH
long to feed case..Good for over 16,000 ft lbs, Regular 14,000 ft lbs.
Will that put trex in small letters.....Pictured with 505 Gibbs to which
it has nearly identical larger shape and good side taper for easy
extraction, with heavy loads.And I can make cases like I do with
my 700HE.Case hold 250gr ball powder under bullet.
It'll work in FBW Model L..ED0 -
hey ed weres the 8 ga industrial gun at ?????????????? 0 -
I don't have industrial gun. I just use bored out NEF
ans swage cases down so that the chamber we use,
will fire regular 8ga as well as new cases we swage.
Shot 4 ga plastic case with 7- 140 gr balls, 980gr total
1800 fps. Used duplex load- Blue Dot 100gr, - Re17 150gr.
A card and couple nitro wads under load and card over, glue gunned
the card in. Shot loadedin two rows of 3 and 7th on bottom
in recess in the middle of top wad. Red plastic case ok some
expansion. Just about the limit for an all plastic case.
Here is picture 0f 585HSM and some other cases.
Gonna test a few in trusty ole Enfield I shot
the 700H 3.25 in with extra rear lugs. Change barrel
lengthen port.It won't do maximum real hotrod
loads like when I put it in PH later, but it'll
outrun trex.2nd pic... ED0 -
In the 4ga plastic case a 760 gr ball at 2000 fps
extracted ok. 3oz #2 shot load at 1500 ok.
More 8ga stuff, fired a 2 ball, 820gr load at 1600
with all the RE17 it had room for. We fired 1300
gr cast full bore 8ga hard slug at 1700. Found a
guy who can do them. Here is picture of his 10
and 8ga cast fullbore hard slugs. 2nd picture is the
585 HSM case sectioned with a competition case
showing how strong brass is.Ed0 -
Hope to resurrect this interesting thread. Aside from the wildcat 12. Have you done any further testing with 10 ga loads?
Or any added research to share on this cool topic.0 -
We found some 585 hardcast, sized and lubed bullets.
Works ok in my 585s at high speed. Shown in picture.
We showed 10ga slugs above, Another easy to do
10ga slug load is the 10ga wadcups for lead BPI has,
with a 69cal swaged lead bullet in it that Dixie sells.
It is hollowbased and 750gr.You can also cast .69-.70
lead slugs for wadcup use. Also use the same wadcup
for buckshot. Some are showing interest in 10ga
due to NEF making them with heavy bull barrels.
Another experimenter has got a bunch
of RMC 3.5" brass 10ga cases, and will load and test
the fullbore 10ga slugs shown above. RMC can do
them about any time you want.Ed0
