Here is picture of my Mossy 695 that has heavy barrel for
the our long 12ga cases, in fact it chambers the 12ga
belted shown in picture ok that I use for testing.
I set chamber to do belted as well as rimmed.
Second picture is some of my 585 Short HE cases, that work
great in regular length actions.We have these in Ruger,
Enfields, Mausers already. I have available supply of
brass for these of about 8-9000. Ed

Here is some more sabot experimenting I did.Shot a couple of
A-Sq 900gr 600 NE slugs in a sabot I made from a heavy
12ga shotcup.Got it to 2300 at my moderate pressures.Here is picture showing slugs, shotcup and one loaded.Shotcup in case
is first one I made- too short. The ones finally used were full
length of slug up to ogive.Ed.

The 900gr in the shotcup was kept at moderate pressures,like all loads due to
what the Savage 210 bolt gun could handle. About 35,000 psi.
It was just an experimental early load to test 600cal 900gr slugs,
in a 12ga shotcup.
My 700HE belted long case, a real hairy case in a strong gun,
like my Vulcan action here, can take high pressures and it gets 1000gr
700 cal bullet to 3200 fps...22,000 ft lbs.
About the cases- The 585 Short HE empty cases are 3 bucks each.
585 Woodleigh slugs are 3 bucks each. Cast 585 slugs are a buck.
The belted 12ga cases above right now are 20 buckss as the 55 Boys brass is
so expensive to make them from.The 55 Boyes cases are being grabbed
up by collectors.Ed

Getting to some more 4ga/bore work.With barrel and
falling block action locked down fired off some blank
type loads to test the breach and firing pin I set up.
I fired it by hitting the back of firing pin with hammer,
as I now have get hammer and trigger setup. Firing pin
dents primers ok, breach works and headspace is ok.
For loads I have wads to take up space above powder.
Others with same 4ga case in doubles fill case about
1/6 full of Blue Dot (110gr), with 2000gr slug.
I'll use 1600 gr hollowbase slugs, with about 1/3 of a case
of IMR 4759 or 1/2 to 5/8 case of RE17, rest filled
with fiber wads.These are shotgun primer loads and I will be
using THE STRONGER PRIMERS OF KILN CASES at about same
price as BMG primers. And I have BMG primer cases also
that I will test also, once gun is finished in a few weeks.Ed

Fired 4bore with 760 gr light round ball with
fiber wads under it, using 150gr Blue Dot
and shotgun primer case. Just starting loads
for testing operation. Hardly no recoil,
like a heavy, beefed up blank load,
could go much higher with that light
of round ball. Will have pics of the muzzle
blast and the gun shooting from the side,
using heavier slugs in a week or so.
In Owen's 4bore double,that uses same case
size they use max of 110gr of Blue Dot
with 2000 gr slug. Ed

Fired the 4bore with the 760 gr round ball,
using 100gr of Blue Dot under 300gr RE17,
total 400gr. Hairy load, with 3500 fps, and
20,000 ft lbs. Used the turned 4bore cases,
with shotgun primers, and with that light
projectile case doesn't need sizing. This is
good beginning bullet weight for early testing.
I am gonna do 1200gr and 1600gr holding the
speeds to give about same energy.
I won't load heavier until I get another
stock like one I have that is full width.
Also those who want 3.5" 20ga brass cases,
Rocky Mtn Cartridge is making them now.ED

Tested 4bore with a double ball load of 1250 grains weight,
Used 100gr Blue Dot under 250gr of RE17, with card and
one fiber wad. 2600 fps. Recoil not bad, just brisk.
Used turned brass cases with shotgun primer, and cases
still didn't expand base. just size top..
Running about 23-25,000 psi.
The light ball load in above post
about 16,000 psi.. Ed
