12GA Rifle From HELL--

[hubel458]

The 80 gr 4759/600gr Dixie slug loads, 3" plastic
cases, with wads and roll crimp, can be used in
modern, alloy steel, smooth barreled, 12 gauges.
A little experimenting and the Dixie being hollow
base can be as accurate as other hollowbase or
brenneke or foster slugs, only
with much more power.Ed

Outside diameter of Dixie slug?

Sorry if you already posted it.

This man deserves the Congressional Medal of Honor.

My NEF is on it's way.
I intend to use Gorilla glue to reattach my retnas .

Let's team up with some support in the way of material, tools, etc.

Has anyone noticed the NEF supply drying up lately?

My hat is off to Ed. Long live his outstanding experimenting spirit.

I don't think so. The MoH is for bravery under fire exceeding all expectations.

However, a Peter Capstick Trophy for cartridge development would not be amiss.

Thanks guys- The Dixie slugs are .729" .And there are
some others that are advertized for smooth also.
And along with Dixies experimenting other
companies are making a few of them heavier than the
traditional one ounce as well, as well as the
lighter sabots.One of the greatest satifactions in
all this has been taking plastic cases and getting
much more power that the factory loads and making
a roll crimped slug load that looks as nice and
professional as those factory loads.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.

Hi Ed:
Have you had a chance to experiment with other powders in the NEF with plastic hulls?

Also, if you were to machine slugs out of copper or brass, would .725 diameter work, or would .729 be the only way to go?

 

[Snappy_13]

think its big enough?

 

[hubel458]

We have tested some turned, brass, Bridger slugs, 750
gr hollowbase and heavier ones. .729 dia, as that what most
rifled 12ga barrels run.Other rifle powders, were RE7,
RE15, H110, H2227, 4198 etc. Thes all need starter
powder like Blue Dot, We tested Blue Dot, 800 hi-skor,
HS-5, Hs- 7 and few other different
shotgun powders and could not get velocity without
pressure peak going too high. Ed

 

[hubel458]

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

Double pumper 870 big bore. 20 shots.
BE Real neat with rifled barrels, and our
4759, plastic case slug loads,
In classifieds on here.Fires both
or one at a time.Ed

 

[mugsie]

You can stay at home with that gun and still hunt in africa, all you need is a spotter over there to adjust the elevation and windage!

 

[hubel458]

I will be posting more research on this thread
about other powders in 12ga plastic cases,about the
12GA FH loads, about scaled up falling blocks, my 700HE long
belted case, and the 28GA FH.Here is picture of
some other cartridges I have with some of mine.
1st= 408CT, 2nd- T-rex necked to 416- 3rd- 600OK
4th- 510HE, 5th-585HE, 6th-700H 3.25, 7th-12GA FH,
8th-700HE. Last most powerful. Ed

 

[hubel458]

For you big bore collectors.Maybe
get some for collections as the guys
who ordered them, didn't take them.
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

 

[ilcylic]

Dang that's cool.

I think I want one.

 

[hubel458]

ilcylic-Are you referring the 4 bore pump or the cases
for it. It really is a nice large bore gun.Ed

 

[hubel458]

Here is picture of first breech block
model that is finished for the
falling block scale up model.
You can see the hammer and trigger
mounted in the back.Ed

 

[hubel458]

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

 

[hubel458]

Rocky MTN is making me some
3.25 in 28ga cases. They are good to 38k psi.
That will get 550 gr out at 2500 in
bolt action.A regular 28ga gun may get to
2000, depending on how heavy barrel is.
Get a NEF Ultra cut off leaving breech section
for monoblock and have 28ga rifled barrel
made and screwed or soldered in monoblock.
And being able to hold 38k to match brass,
That would get 2500 fps loads.Ed

 

[hubel458]

There is a possibility that we can take big
spanish doubles in 10/12 ga and rebarrel to 28ga
now that there are .550 barrels around. Put them into breech section of barrels like monoblock doubles are built.
They'd be heavy enough barrel to shoot powerful 28ga
slug loads in the brass cases. Ed

 

[hubel458]

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

 

[hubel458]

Here is picture of the first falling block
model of aluminum, with a roughed out
stock to see how it looks. Action is a
rough model. It shoulders nice, and
lever is inlet into pistol grip,
so you can't get banged up
fingers with the big cartridges it is designed
for, like levers that stick down at the
guard.Ed

 

[hubel458]

Tis stock is of modern big bore layout.Older
styles with more drop at heel can be used.
Comb is uphill a 1/4" at back from comb front.So
it won't hit the face. The front of comb can also
be whittled back and more curve added to top of
the grip, if a longer tang is wanted for the
tang mounted ladder sights.Ed

 

[hubel458]

Thr rear top of action will have recess for mounting
any length tang needed. Also lever can be straightened
for pld style straight grip stocks. Ed

 

[hubel458]

Here is pic of action model with lever open
and the breech block down. Also the action
will have a slot in the rtop rear for a
top tang of whatever length you need.Ed

 

[hubel458]

Info about the toggle link. It is up inside
the breech block, and quite short,and that
allows the overall height of the action to
be relatively compact, for the huge
cases we plan on using.But yet the top
part of the breechblock is solid for
great strength.Ed
