Here is simple outline of what we did-

Made super strong 12ga long brass case to
take heavy slug loads...10,000 ft lbs energy real easy

Made heavy barreled strong 12ga guns to shoot them,
by using heavy barrels, beefing up actions, adding weight,.

Researched how to use regular strong guns with brass
and plastic cases to get twice the power out of a 12ga.
Using 2.75", 3' , 3.5" chambers.

Found heatreated hardened slugs that will take the speed and
deliver the power to the target.

And now designing falling block action for big case.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

For you big bore collectors.Here is
a gun that make good buckshot
deer gun. Use big buckshot.If
your into collecting cases - Maybe
get some for collections as the guys
who ordered them, didn't take them all.
There is a whole bunch of the Tula 4bore
cases at Rocky Mtn Cartridge Co.
This was the run we had made for the
Tula 4bore pumpgun. It's a 3inch 4bore
case. 20 bucks single case, shipping and all.
The price of brass and machining is twice that.
Here is pic of the gun it went into.Ed
