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 the 630 gr use
a BPGS and Flexseal over powder.. Ed

More info about the seal and
More info about the seal and cushion for 16ga
630 gr slug. Plastic seal works best.
It is a BPGS type seal, IE, a one way seal,
and a flex type cushion. The seal/cushion,
is the bottom part from a 16ga wad cup.
Like bottom of trap commander wad.Ed

Here is picture the CBC 20ga
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"..Ed

Here are some 20ga
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.ED

Here is picture of the 4bore
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. Ed

I found 3 long brass 8ga
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.Ed

The long brass 8ga cases have
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.Ed

New super strong 12ga bolt
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.Ed

Some more info on the Savage
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.Ed

Would have posted back
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 bases. 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..Ed
