12GA From Hell in a break action--

[hubel458]

Here is picture my NEF, soon to be, 8ga gun.
It weighs 15 lbs. The hollow butt and hollows
in the forearm are weighted. It has a neat recoil
barrel ring I added so forearm stays put.
It has internal brake on barrel that I picture
earlier in thread with the porting holes.
Second picture is a Lyman 520 gr slug on the right
that we are testing . They go in regular 12ga shotcups,
and many folks have good accuracy with them, even
in smooth bores. They are hollowbase nose-heavy
design. These are the ones you cast your own.
And there are guys casting some for sale.
You see two in wadcups on the right.
On the left is my prototype of the Lyman
style, of 900gr for our 8GA FH. Going to get a
mold made. The base of it will fit the 8ga shotcup
used in the kiln gun loads, and the front will be our
smoothbore 8ga size, .832-835". I designed this
as the flat ended kiln slug without a hollow
base and heavy in the front, wasn't designed
to give 100yd accuracy in a smoothbore. Ed

The picture is some aluminum cored jacketed slugs

RG made, weighing 385 gr. Full .730" diameter, hollowpoint,

and one I filled nose with glue gun. Fairly streamlined. 3600 in

the Savage with our long case..Slug is nice and long,

1.22" HP and 1.4" with plastic I put in the nose.

In Nef with RMC 3.5" brass case 2700, 3.5" plastic 2500. Ed

Any exspansion testing on those HP's?

[hubel458]

Not yet, just chronoed a few, It is zero to ten here and looks
to stay that way for rest of the winter.

RIP on AR forums been testing starter powders loads, with
shotgun primers,with Blue Dot starter and HBMG main load. And
I just tested some variety of ones myself.
Doing some testing with starter powder, 15gr Blue Dot, with
slower powders that fill the cases with minimum wads.
Tested in 3.5" RMC case in NEF with shotgun primer,
with 36" added to barrel.Remember I have extra foot of bbl.

These 4 top loads expanded case, where I check it, just above
thick base section to .811" from .807" resized.

1000gr jacketed, 230gr HBMG, 1800 fps, 7200 ft lbs,
with 1/8" card and 1/4" felt wad.

715gr jkt, 270gr HBMG, 2200, 7600 ft lbs, 1/8" card.

600gr Dixie, 250 gr Retumbo, 2400, 7600 ft lbs, 1/8" card.

385gr jkt AL core, 250 gr RL25,2900, 7200 ft lbs.
This is faster than lighter loads in NEF, using 4227 powder.

Now the starter powder loads, which a few guys like, increase
powder speeds so that HBMG acts like RL25. In first example,
with 1000 gr in RMC case you couldn't use 230gr of RL25
as that would expand RMC brass too much and stick the case.
A few guys have found that slow powder, with starter
powder is easiest for 1000gr and heavier loads.

On another note, I've heard around the grapevine that if
enough of us ask for NEF to make available a 12ga Ultra with
a 28" rifled bull barrel that they would do it.Start calling
folks, maybe do some good. Just tell them these new sabot
and fullbore slug loads need more barrel to get the velocity
out of them. 1-866-776-9292. Ed

Here is picture of 28GA FH brass case with the 350gr
Lyman cast slug. It is the slug you cast to use
originally in 20ga shot cups, for slug hunting.
It is nose heavy and will work in smooth bores.
Brass 3.25" cases from Rocky Mtn Cartridge. It
will work in NEF/H&R 28ga modern break action guns
that cost 150 bucks, 26" barrel, you lengthen chamber
for the brass case. Good hunting loads would
be 2000 fps and the gun with a little weight added
and good pad would handle it fine. Had a few guys ask
about 28ga slug shooting, here is away..Ed

[hubel458]

Here is a double projectile load that would make a
good defense load. Two Brenekkes doubled up in RMC
case in the NEF. 85 gr of 4227 pushing 2 one
ounce KO slugs about 1600. Bottom slug has seal.

Also found a way to adapt extra slugs to 10ga. A
515 gr Lyman slug originally for use 12ga wadcup,
but now a way to use them in my NEF break action
10ga, by using thickwall 10ga BPI steel no slit wadcup
shortened and Lyman bottomed out in it, so it
is like a discard on impact sabot slug. Like Lightfield
and Hastings. I shaved the bottom diameter of Lyman
so it would fit tight. Similar deal for 16ga using BPI 16ga
no slit heavy shot cup and 20ga Lyman. Now we have it
so that the 2 Lymans can fit 10,12,16,20,28 ga....Ed



PS- I ask all of you for a favor. Would you please go
to the thehighroad.us forums, join in and support them.
The owner has had original Highroad domain stolen from
him and he is in court to get it back. He is in
the right and if you folks show up it will give moral support.
And if you can stand it until court rules stay away from
the first highroad and ask your friends to do the same.

Here is 12ga prototype cushioned base sabot I put
together to show how heavy of powder seal
and heavy cushion base that is needed. That
eliminates the blowouts and damage that was
happening to sabots unless I put a card
under sabot. Just used a Brenekke seal/cushion
base, epoxied to bottom of sabot. Even fired one
and it got out the barrel and 437gr slug hit
target straight. Ed

Some 8ga experimenting and info. The 8ga chambers
I have are set up to fire the regular 8ga
size cases, and also REM kiln cases with bases
turned smaller, where the extra short basecup
is formed over the inside cup.Just reduce to the
diameter that it chambers ok and regular case
doesn't expand very much fired in same chamber.
This idea came from UK 8ga hunters that found
it was easier to get kiln cases. Now the other
case in 8ga available is the WIN kiln case and
ones I've seen are only single thickness basecup,
but they have the step formed in them to match
the kiln case belt size. Now you can't turn them
down any to fit my chamber, BUT you can swage
them down .012" in a die with a lttle lube on the
basecup. Examining them they do expand much more
than the doubled up REMs.I fired REMs 4-5 times
with bases expanding .002", the WIN I did
expanded .005" in one shot.Easiest to use
heavier built REMs as they are only 70cents
primed and good for 4-5 shots,
no resizing, with semi-hairy 8,000 ft lb loads.Ed

I glued up 3 of 12ga prototype sabots. At 25yds( the 50yd range
is in the water and snow) And the three with 437gr .512"
slugs I did one 2" group with peep sights and bad eyes.
Running about 2400 fps from RMC case in the NEF 12GA FH
Shot 3 of my 28ga FH with Lyman 360gr at 2100, from
the Enfield 28GA FH, and got same size group.Real windy
when testing . Going cold and ready to snow again.
Shot a 600 grain Dixie hardened heatreated slug, in Savage
in our long case at 2900 though two-- 1/4" steel plates with
2" of wood between them. Made big hole.Ed

[hubel458]

Before it got cold again got little more testing done.
I shot 8ga Lyman 900gr wasp-style slug out of
the Enfield at 2350. I made it from heat treated
lead REM kiln gun slugs, and it went through 6 foot
of hardwood slabs in my backstop. Hit target square,
behind chrono, which is great from smoothbore.
It is hollowbase and seems very stable.And real hard.
I shot 3 shot group, with 12ga 525gr Lyman, in 87
smoothbore long barrel levergun, At 25 yards they
all made hole like cloverleaf. Used 3.5" RMC brass, with
Lyman in a WW12-114 shotcup, going 2100.Now my
87 smooth barrel is .722" at muzzle, .726" at breech,
so it gives tight support to shotcup and Lyman slug,
for fairly accurate load.....Ed

Here is picture of one of RIP's NEFs 12GA FH, with
a Vias brake installed. He had smith ream out a
50cal one to let 12ga slugs pass through...Ed

[hubel458]

Here are some results( had 1 nice day) with 8 gauge and
10ga light slug loads of my testing. I call them my real
big bore varmint loads. A 770 gr slug in 8ga fired in
Enfield at 2400 all 3 shots nearly touching at 20 yds.
A 515 gr Lyman, NEF 10ga at 2400, same tight group
at 20yds. Lyman is originally for 12ga, but is fit in
10ga thickwall BPI shotcup cut off and slug glued in so
it is like a impact discarding sabot. Both smoothbores.

Smaller varmint load. NEF rifled 12ga with RG's 385gr
aluminum cored jacketed HP slug at 2700, 2 overlapping
and one half inch away, using RMC 3.5" case. Here is pic
the 3 slugs for comparison. First is 770gr in 8ga wadcup,
second is 515 Lyman in 10ga wadcup, third is the
12ga 385gr HP with aluminum core. Ed

[hubel458]

Here is what a 600gr super hardened Dixie slug
at 29-3000 plus does to two mild steel plates with
2" wood between them. Fired from our long case
in the Savage.Two plates are soft mild steel.
In hole nice and round. Out, in back plate jagged.
Anyone interested in the 12ga Encore
with 3.5" chambers, that I tested loads in,
it is on Gunbroker..Ed

[hubel458]

Here is my 12GA FH Savage 210 with thumbhole
stock, I put on in place of first one that cracked.
First one didn't break as such, just got crack
on the side where there was couple knots.
Along with weight and heavy barrel, handles recoil
great. It is a Boyd and came inleted for Savage
112, and I re-did inleting to fit 210 and
heavy barrel,and got rid of monte carlo
outline, and added full height thick pad.Ed

Really enjoy reading about what your doing. Keep up the good work.
