A DU sabot. That would be something.
Buckhammer 3 "factory loads are 15k psi.
This is a from the factory load.
A 2.75 inch case with 80 gr of 4759, a thin card wad,
a 3/8 cushion lubed felt wad, when crimped is about
2.4 inches long, with 600gr Dixie slug. Based on
pressures recorded in previous post for 3 inch case
and 90gr of 4759, they will run about 13,400 psi,
and work through modern guns.Another load tested with
same bullet, 65gr of 4759, tested at same place
was 11,800 psi and 1640 fps. So you don't have
to put in my max loads, but go down a
little and use in modern guns that
are lighter than NEF so they don't kick so bad.But yet
you can get fairly good energy levels for big game, 3300
to 4000 ft lbs of energy.Ed

Here is picture of top part of the
first scale-up model, next to smaller
Wickliffe. It has 12GA FH round in feed
trough. It is aluminum just for a model.
It will handle 12GA FH, 700HE, 700NE, 600NE,
etc. Bottom of block is flat to set on
mill table to do the machining.Next machining
will be the hole and slot down through the
action for breech block and hammer to
slide up and down in.Its taken awhile to
get some tooling.I had none when we set up
vertical mill, and have to get more.The
action model also will be narrowed up when
finished, and contoured to look as good
as the Wickcliffe.Ed.

Tested the Wickcliffe with 12ga FH case
in a temperary chamber to see if
hammer with beefed up spring would fire
bmg primers.I scalloped out the back
of the action so 12ga cases would feed
into the action and temp chamber
They fired ok. Bur the extra stiff spring
makes it hard to cock. We will have to work
on that.The original Wickcliffe
action that we want to scale up is tall
enough so that when breech block is
lowered the block clears the bottom
a 12ga rim when cases slide out of chamber.
So in the scale up we need to just add a
a little width for wider breech block,
and the bigger barrel thread, and keep the
sides thick for strength.Ed

In response to guys who can't find 4759
we will test powders in the same speed range.
Tested 2 fast stick powders, 4198 and 4227.
Both didn't ignite good with small primers
in plastic cases. Another I plan on trying
VV110, when I find some. It is bulkier
and slight chance may work like 4759. Ed

Fired couple 3.5" cases with 90gr
4759 and 460 grains of buckshot,
14 number 1 buckshot.Fired in nef,
pattern huge due to rifling, even with
shotcup. They were going 2000 fps plus,
and went through 1/8 steel on end of
stand. Ignition perfect, extracted easy.
In smoothbore be a real hairy load.
With three 3.5" plastic cases with
100gr 4759, 600gr slug. Used .135 card wad,
a 1/2" and 1/4" felt wads. 1900+ fps
in 24" NEF barrel, same low pressure as
the 3" cases we pressure tested. I have NEF
chamber lengthened for our longer
brass case. A nice long barrel we'd
have 2050 plus.Ed

Here is pictures of the breech, lever,
linkage, etc, set up on a block to
get the geometry for the scaleup model working
ok.And setup measurements to make the breech
hole in the action, in right place.Also used
this model to get hammer and trigger set
up to ride on the breech block. With
a strong hammer and trigger in the right
place in the guard.In the pics above you see the pin the
lever pivots on. The actions being bigger
will be wider than the levers;So the space on the
pivot will be taken up by the Ruger
style extractor on the left side and a spacer
on the right side. Spacer also acts as a
breech block stop at the bottom of the
breech travel.So to get block stopped at
right position for the diameter of the case
and feed trough, we adjust spacer size.
Ruger extractors from GP changed
a little bit will do.Ed.

Found info an a double that would work
for making 12GA FH. It's a Spanish 10 ga
on an 8 ga frame that we think Stoeger and
maybe others imported years ago. It says
No. 6 HG on trigger guard. It is over 2 & 3/4"
across outside of both barrels, chopperlump
barrel pivots, with heavy locking lugs,
and A purdey style third fastener.Top lever.
Barrels are big enough to use as monoblocks
to screw in heavy 12ga barrels, with same size
threads as my Savage and it being a huge action
could handle same loads as the Savage.Like
12-17,000 ft lbs. Ed.

Here is sectioned action with parts in.
Original action that had defects
that I sectioned down the middle..I
ground out the top to allow case
to set higher, representing a
the taller action that we will
have due to larger diameter cases.
That lever in the picture is the
lever we will use with longer stroke.
Also in the action layout is the
breechblock, hammer, trigger with a
12GA FH in front, all in to check layout.
This lever looks to be easier to fit
and shape to bigger action and stock,
with a good pistolgrip to handle recoil.
Lever shape fits where trigger is better.Ed

This is nuts, The results after hunting with this cartridge would be horrific. There is this guy that i read about who hunts deer with a .50 bmg usually at long ranges...or else no meat would be left.

Hairy results are needed for dangerous game and can be
loaded down for deer and hogs in our
long brass case, similiar to the 4759 loads in 12ga
plastic cases.They are only 25% faster than factory
slug loads, just giving a 150 yd point blank
range. Better than 80 yd range and that 25% ain't
going to disintegrate animals. Ed.

Here is pic of the finished breech block model
for the scaleup action.You can see hammer
and trigger mounted in the rear of the
block.Ed

Another experiment in shotgun/rifle realm is
28GA From Hell. 28ga is .550 bore and with 550Mag
barrels & bullets being made it is a natural. Have one
on bolt gun ready to chamber.Chamber still
will fire shorter cases..Ed

Tested AA2015- VV N130- Norma200- in plastic cases with small primers. They don't fire
dependably. Sqibs and misfires. Have
VV N110 ordered to test.Have had inquiries
about getting our cases shortened for strength
and they want to put in small primer.
They can be adapted with bushing. Ok but
must use 4759 or fast shotgun powders,
if they are used by themselves. Any slower powders, a fast shotgun starter powder
is needed. My testing shows RE-15 with 10gr
of Blue Dot starter is best of all we tested
in slower powders for shorter cases.Ed
