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

Here is picture of the 3.5" 20ga brass case in
FBW falling block. Nice cases by RMC.Shotgun primer.
Using 395 gr sabot get over 2700 fps. 600gr
over 2200. Cases take many reloads with
minimum sizing. One fired 8 times, still good
and the slower powders get the velocity
without the hard shock to cases, compared to
fast shotgun powders. And the hotrod Hastings
factory loads work in the gun also.
Guy got new design 8 and 10 ga slugs with
bigger hollow in the base. 1100gr for 8 and
900gr for 10. More accurate in smooth bores.
Will let everyone know when he is ready to
make a few for shooters.Ed0 -
I like singleshot break actions. I found another brand that will work
to make heavy barrel 12 and 20 ga FH. By monoblocking in heavy
barrels. It is the CBC Model SB. It has stock mounted like more
expensive doubles and O/U. And nice shaped pistol grip stock.
They have the nice stylish look like the Win 37 and Stevens 94.
But they are heavier built, just need heavy barrel.
I going to do a couple by monoblocking in heavy barrels, one 20ga
and one my 585 HE like I did in the NEF.And they are 50 to 100 bucks.
That action is a 1/8 inch wider than NEF, big barrel breach diameter
like NEF 10/12 gauges. The bearing surfaces on the pivot is .300"
wider, and pivot block is 1/4" wider. Pivot pin is 1/10" bigger.
The action is a 1/2 inch taller, and extra diameter at breach end.
In fact you could build a real hairy 8ga on its wider action, with
a heavy barrel and a new pivot block welded on.Ed0 -
More info on doing 20ga 3.5" in break actions. Nice
to do them in falling blocks, but they aren't available
for decent price. One choice, heavy barrel NEF 20ga,
lengthen chamber, but barrels are too short for proper
burning of large loads. Longer barrel better and helps
with recoil. And in a break action looks better to me.
Brass cases from RMC 7 bucks, decent price compared to
600NE brass at twice that. Many guys want 20s along with
the bigger. So you put a heavy barrel in a gun like the CBC
which is low cost and put extra toward the barrel.
Which is why I started research after getting a CBC,
as it is about perfect for the 20ga added heavy barrel.
Or in NEF, a little more. Or other singles, if heavy enough.
And you still fire factory 3-3.5" slug loads. And 3.5" brass
20ga will do same as 600NE factory loads, in a gun at
1/20 the price. That is reason we are looking at monoblocking
20ga barrels to make heavy strong guns, that can
get great velocities, less cost.. Like 600gr to 2200 or more.
Added heavy barrels in right actions will hold all the
pressure the RMC brass operates at. And remember one
experimenter has 20ga kills at 160 and 230 yds on deer.ED0 -

More info on 10 and 8 gauge slugs. The guy got some
made with deep hollowbase, 10ga 900gr, 8ga 1100gr.
He will make them for a buck each.
Bob Bigando in AZ. (bobiano at yahoo.com)
Good price as they are nice hard shiny slugs.
For seals for 10 and 8 gauge you can get regular
card seals and nitro fiber wads, but plastic seals
will do better, about a 100 fps in the faster loads.
Plastic seals for 10 ga are at BPI, called - X10X.
For 8ga I cut bottom seal part off of the 8ga wadcup
that BPI has. For extended accuracy in smooth bores
you can screw the seals on to the slugs and that
will make the overall projectile more front heavy.
Or better yet screw nitro fiber wads to the slug,
like the Brenekkes are. Good smoothbore accuracy
Use slugs with seals on, with slower RE17 that fills
case so no fiber wads are need.Just seal and slug.ED0 -
Ther are some who like and need
8 and 10 ga slugs for smooth bore with
wads screwed on. Just drill small hole in bottom of
hollowbase and use screw and washer.Drill
small hole through wad. I use 1/2" wad with
front of wad shaved so it is in base.Ed0 -
I talked about these 12ga jacketed full bore slugs earlier,
shown below. Well now BPI has something similiar in
their new catalog. We have tested some and one guy
got a 3 shot group that is nearly touching at 50 yds
in a scoped NEF Ultra slug gun. They can go real fast in
our 3.5 RMC or our real long case.They are hollowpoint
and fairly streamlined.I fill them with plastic glue for
better streamlining.Fullbore and no sabots needed.
Relatively light weight, to lessen recoil.Ed0 -
The 12ga Brenekke slugs with locked on base and the USS-S
slugs I test have led to other combinations that I've put
together using different slugs and wads. The object is
60 yd accurate, economical slugs for reloading smoothbores
that in the reloading process we can get more power also.
Like the Lyman cast slugs in thickwall 10ga steel wads,
with the slug glued in and wad cut off even with top of slug.
Then with wad cut even, you load and can rollcrimp perfect.
It makes a real nose heavy combination that is as accurate
in smoothbores, as the expensive 10ga foster style slugs.
Another one is the hollowbase 577 soft lead slugs that Dixie
sells, I put in a thickwall 16ga wad that BPI has. I glue it in
using Goop, a thick glue that hardwares sell. Epoxy works.
Another one is 20ga ga thickwall wad with 54 cal hollowbase
soft lead slugs. All these and others can be loaded for a fifth of
factory for smoothbores, and be as accurate as foster slugs.
And our slow powder loads seal good with wadcups.
Representative one in middlle, 10ga.Slug glued in tight.Ed0 -
Some wonder if only trying for foster slug accuracy at 200 feet
or 60-70 yds wasn't the best goal in a smooth bore, But if you get it
at 20% of the cost you've made a big gain. And most deer here are
killed at 30 yards. And putting slugs inside of thickwall wadcups,
with corresponding nitro wads under slug to get slug to the front
of cup, slug glued in, makes them long and a little more accurate than
foster slugs. Reason is the forcing cone in smoothbores. With the
long nose, heavy combination of wadcup/slug, the back of the
wadcup is in case yet while the front gets into the bore, past the
forcing cone, for a straight start. Little better accuracy. Like the
accurate US-S smoothbore locked on base slug, that is long.
The longer the nose heavy slug/sabot combo is, the truer it flies.
And most of these combinations work in brass cases with
thick walls like RMC cases. They fit real tight for my cases. Ed0 -
Penetration with slugs-Had a bunch of
wood blocks up to 12" through.
20ga load is a 54 cal 410 gr slug glued in wadcup.
Gives the same effect as Brenekke with locked on base..
Good in smoothbore at 50 yds.Goes through
6" block of wood easy/
Buckshot load in 4bore, 9 140gr 45cal balls at 1800,
all zip through 3/4" OSB and keep going.
In 4bore 760gr steel ball zips through 12" block of wood.
going over 3200 fps. Wood is dried hard poplar.
In 10ga 3.5" plastic case, a 900gr hardcast slug at 1800
fps, through same kind of block easy. This slug I put
on a screwed on base with plastic seal and wad.
I've also put plastic seals and fiber wads on 8ga
slugs to test later..
12ga 600gr hard slug at 2100 zips through 12"
wood block like it was putty.In a 3.5" RMC
case in NEF.
Anyone wanting one of my loaded 585HSMs to
collect or look at, let me know. 750gr
slug in this at 2800 in Enfield test gun.
Soon have barrel in PH and put the real
speed to it. About 33-3400.
Will soon have the heavy 20 ga barrel mono-blocked
into the 12ga barrel setup on the CBC break action.
Make a nice looking gun. Also going to put the 8ga heavy
barrel I had in Enfield for testing into falling block
built like the 4 bore one.Maybe done by summer.
Will be in one piece stock like 4bore.Ed0 -
Finding real slow powders that works with shotgun primers,
without starter powder. We found RE-17 and surplus 7383.
To recap faster rifle powders we use -VV110,IMR 4759,4227..
On the thread we've written about real slow powders like
H-BMG we've used with a starter powder, IE 15gr of Blue dot,
and H-BMG in amounts from 150 gr to 230gr in 3.5 and 3.85
inch brass cases. And 3.5 " plastic cases. 860-1040 gr slugs.
Tested in NEF with long heavy barrel.
We finally got some RE-50,a really slow powder like H-BMG.
It works with a real magnum shotgun primer with heavy slugs,
860 gr on up, in 3.5" RMC brass, 3.5" plastic and our long
brass case. I used 239 Fed primers. Lighter slugs
only give squib loads.RE-50 Is a powder made like RE-17
with the deterrant all through the grain of the powder,
rather than all on the surface of the grains, so it will ignite
easier, to get the initial combustion started.
In brass case used 240gr with 860gr slug, 1950 fps
and 220gr with 1040gr slug, 1750.
In 3.5" plastic 860gr slug with 180gr RE-50, 1500 plus.
Now these velocities aren't earth shattering as powder is real
slow, but cases don't expand, not even plastic case base cup.
And no starter powder. Nice thing is just fill cases
leaving room for slug and seal and no worries about
to high of peak pressures with heavy slugs
or cases expanding to stick.
Now to get 239 primers get Fed 12ga long red
3.5" primed cases from BPI. I used Fed cases,and took out
primers and used in other plastic and the brass cases.
Some guys trying to free up 239 primers for us reloaders.
Federal puts them in 3.5" mag 12ga loads and 10ga cases.
Elsewhere it was reported someone may do a 16ga sabot.
Also a guy got huge antlered buck with hotrod 20ga. Ed0 -
ed if you need any powder slower than that i have it listed here on the gb site advance search under seller name shady grady 0 -
I have a way to compare primers without powder and slugs,
for a lot of my experimenting. I use a short 24"barrel 10ga.
The barrel being shorter I can see the sparks and flame.
I fire off the primers in case with no powder/slugs.
I have just tested to see if magnum FED Fusion and Triple 7
inline muzzleloading primers were as strong as FED 239.
Just the two brands to test in the 10ga to compare flame,
sparks and bang, and they were not as good as the 209
Remington STS ones I like. They only put a few sparks out
of the barrel.The REM 209 STS and Fed 209 M had 3" fire out the
barrel and the Fed 239 had about 5-6" out the barrel. And 8ga
Rem and Win kiln case hotrod primers 8" plus....
Previous post I mention trying to start H-BMG slow powder with
8ga kiln primers without success. Which is why we figured out
using a starter powder like 15gr Blue Dot. Then it works great
with any shotgun primer. Guys here when they see misfires with
shotgun primers and H-BMG only, and the see starter powder loads
go off in our big 12ga case like a tank cannon, they are
flabbergasted at the difference.ED0 -
I mentioned in the threads earlier a 16GA FH case
I made from bmg brass. Then I put it in a 16ga
Stevens 94 break action by lengthening chamber
for the 3.5" case. I kept speed and pressures down
as the regular barrel on the gun had a thin muzzle.
Now I found a thick heavy 16ga 32" alloy tube and
I had extra Enfield test action, with the port
opened for longer cases. I turned it 1.1" at the
muzzle. Nice and heavy. It does a 630gr 16ga
'Greg S' slug 2400 and 385 gr Lightfield 16ga slug
to 3000, without the bottom 2/3 of the case
having to be resized. With RE-17. I have these cases
setup for shotgun primers.The Lightfield has it own
seal on the locked on base and for 630 gr use
a BPGS with flexseal under it. Ed0 -
More info about the seal and cushion for 16ga
630 gr slug. Plastic seal works best.A clearer description
It is a BPGS type plastic seal, IE, a one way seal,
and a flex type cushion. One way seals best.The seal/cushion,
is the bottom part from 16ga wad cups.
Like bottom half of bottom trap commander 16ga wad.Ed0 -
Here is picture the CBC 20ga FH setup
by mono-blocking a heavy 20 ga barrel
into a CBC 12ga breech section.The 20 heavy
barrel is threaded into the mono-block made
by cutting off 12ga barrel. These CBC actions
are taller and wider than other break actions
and the locking lug block works better and
nicer than other break actions.Also shown
is 20ga 3.5" plastic and brass cases.
Second picture is PH action with port lengthened
for 585HSM, shown in action. I also have second
change barrel for 700HE long case for this action.
Imagine over 20,000 ft lbs in a PH, for 700HE.
Also shown behind is a PH with 700H 3.25"..Ed0 -
Here are some 20ga slugs/sabots we rigged up.
I traded for whole box(hundreds) of 20ga Hammerhead
slugs, in the picture. They had pulled slugs
out of the locked on plastic base, so I glue them
back in so base stays for fair smoothbore accuracy.
And I also glued in various 458 bullets, as shown,
which fit tight in cup, up to 500gr. They discard
on impact. Fair accuracy at 50-70 yds. Less expensive
shooting as I have pile of hard lead 458 slugs.
Idea on 8ga FH. Looked at a TCR87 break action 10ga
and the breach mono-block can take a little bigger
barrel.If I find one I can afford(pricey) I'll do 8ga.
These are very strong actions, a little smaller version
of the action setup Colin put the 2bore in.
Just put in straight 8ga bull barrel like NEF Ultra.ED0 -
Very Nice!!![:)] 0 -
Here is picture of the 4bore in a more finished look.
Second picture is closeup of cases and 1520 gr
hollowbase hard slugs. The 4bore is smooth bore so
hollowbase slugs are used. I set up gun with
smoothbore as that saved large amount of time and
money on the barrel. Ed0 -
I found 3 long brass 8ga cases to go with
the 3.3" plastic ones. They are an inch longer
and made by RMC. The 8ga barrel I'm putting
on a falling block will have the chamber long
so I can use both lengths of cases.
The plastic ones are from 8ga kiln cases with base
swaged a little and has shotgun primers, The
long brass has shotgun primers.
I use Fed 239 shotgun primers.Ed0 -
The long brass 8ga cases have same thick
sides as plastic cases. And there are long
plastic/paper cases out there, but they
are scarce. Thick sides mean a good chamber
fit, so as to minimize case expansion and make sizing
easier. Here is picture 8ga and 10ga fullbore slugs with
locked on basewads that I setup. Wads held on by
screws and slugs hollowbase as well, so to work in
smooth barrels with some accuracy. 8ga is 1100gr.
10ga is 900 gr.Ed0 -
New super strong 12ga bolt gun just out, Savage 212, taking
over for the 210. You know I did my first 12ga FH in a 210 and
have posted that sometime I'd like to get a thicker walled
reciever built to have more strength and safety.
Well Savage helped us out.
Its reciever is 1.5" diameter, where the 210 was 1.36" dia.
I has a large .900" diameter bolt, where the 210 had regular
110 bolt inside bolt carrier. It has a fitted bolt head like 210
and other Savage 110-116 rifles. Only its bolt head has two lugs
where the 210 had 3 lugs. Its two lugs about 90% strength as
the 210s 3 lugs.Its about 12% stronger lugs than Enfield and
Rugers. Also it appears the bolt raceways are not through the
barrel thread area so about 50% stronger barrel connection.
Price not too bad 500-550. I'll try to find one later to do some
hairy cartridges in. It has a 3" 12ga chamber from factory and
detachable magazine. Probably can have mag and port lengthened
and feed ok, with 3.5" 12ga and the 700H 3.25". More info
as I find out stuff.Picture from auction-e.Thanks to
Bob in OR for info.Ed0 -
Some more info on the Savage 212. I looked at one,
got more measurements. The port is 3.812" long.
Can be made longer. Bolt travel is 4.625" and can be .50"
longer. And with full diameter bolt can have extra
lugs in back. The Mag box has room for extra length in
front of it and behind it. It could work for 12ga FH
and 700HE long case.
A fellow on Gunsmithing forum found a way to make
jacketed slugs using copper tubing caps, the solder ones,
by putting them in a die and using a shaped punch to form
a round nose copper jacket, that can be filled with lead.
He made .700 cal ones, different dies/punchs could
be made .729, 12ga size. I got a few here and going to see
what is possible. I got bigger caps also to see about 4ga
and 8ga ones. Here is picture of the CBC break action with
the 20ga heavy barrel mono-blocked in, with action open.Ed0 -
Would have posted back quicker but computer
hookup down for afew days..
Here is picture of 16GA FH I mentioned earlier doing in
an Enfield. Got 630gr slug 2400, compared to
the first 16GA FH in thin barrel break action at 1600.
I use 630 gr full bore slugs and the 385gr SPW
saboted with locked on base.
Opened port and changed bolt stop. Reamed
front so case fit through action into barrel and added extra
rear lugs. Same process that is used to do Enfield
in my 700H 3.25.
I got some of the work done on 8ga in my falling
block design, like the 4ga I've done pictured earlier.
Will get pictures posted later..Ed0 -
I plan to build a 8 GA.shotgun on the CBC action. What is the outside dia of the 12 GA. barrel in the chamber area? 0 -

OD of chamber area is 1.18" If I was going to
8ga CBC, I'd make full use of the 1.3" wide
CBC action and make barrel that diameter
and just mill circular part of action down
.060, half the difference, for a 1.3" bbl.
Experimenting for fellows trying to get speed with heavier sabot slugs than
the lightweight saboted 4-500 gr kind of slugs, in 2 5/8" length brass
cases for where length is limited..
Using 770 gr saboted slugs with locked on base, by US-S.
Thes are long saboted slugs due being brass and locked on base.
Real hard to do with these due to lack of powder space for the RE17
and IMR 4759-4227 that I like to use. With 770 gr and 60gr 4759 got 1450 fps.
With 75gr Re17 about 1350 fps. Both of these all case will hold under sabot.
For contrast using full bore 730 gr Dixie with just seals under it, much more
powder room, with 95gr 4759 getting 1800 plus and 130 gr RE17 1700 fps.
I went to faster powder, my slowest shotgun powder, Alliant steel, to try to get
speed like full bore slugs get.
These listed are max loads before brass cases expanded to much and started
sticking, due to sharp expansion step, where the base goes to the side with a
real small inside radius on this particular RMC brass case.
47gr Steel,and 770 gr slug 1400 fps.
So I tried the 570 gr US-S with 53gr Steel,and got 1700 fps. Same slug with
65gr 4759 got 1650. You can put in more Steel but cases stick.
And cases expanded that way are hard to resize.
The first 3" brass I got years ago, same problem with
a sharp step expanding above the base. So when I had 3.5" brass made
I had them do a long inside radius from base to the sides. These with extra
room for powder and cushion are much less problem. I think where you have
to use shorter cases, you can use plastic, as a 3" plastic is 2 5/8"
when crimped and will do the same and only be 20 cents or so new.Ed0 -
Thanks Huble458,Here what I thought about doing:using a piece of 1" scedule 160 seamless steel pipe. The pipe measures 1.315 OD and 0.815 ID. A 3 foot section can be obtained for $130. 0 -
Yes that will work and so you could fire the 8ga
.832-.835" slugs being made just run an adjustable
or exact size reamer through for right size.
That is what I do.
Here is picture of a big bolt action a fellow on Homegunsmith
built to put big cases in, for his own use. It is of better looks,
quality than most other single shot actions, of that style being
built by others for sale. And that is absolute
sexiest bolt handle.
Also the fellow made a recess type of die and shaped punch
to make large caliber, copper bullet jackets, from plumbing
copper caps, and then put melted lead into them from
the back. He uses a big hammer, works great.
I got a few different sizes of caps and they are
perfect for bullet jackets. Right from hardware or plumber
supply places. ED0 -
Answering questions; bullet jackets from copper tubing
caps. This process makes jacketed slug with covered
nose. With heavy soft jacket as opposed to a
solid turned slug from solid rod or soft lead slug.
1/2" caps can make .700 and 12ga size jackets.
5/8" caps can do 8ga and maybe 10ga jkts.
And 3/4" caps can make 4ga. These cups are
malleable enough to shape into jackets,
without a 20 ton stamping press.
