Still testing 8ga I have setup in the Enfield.
It has a long smooth barrel. Those 8ga
heavy plastic cases are great. Fire them 4 times with
no resizing. Here is pic of slugs used in 8ga..
One and two are 1015gr hollowbase. Three and 4 are
875gr hollowbase. On four the cushion base is cut off
so I can use card wad and have more room for
We got our RMC 3.5" brass 12ga cases. These are turned
cases using shotgun primer. They have nice thick base,
and a good radius in the corner. Got a Brenekke OK 437 gr
slug to 2800 fps, a 540gr Hammerhead slug to 2450. got 600gr
Dixie to 2300, the 715gr RG jacketed to 2130, and a 1400gr
Darwin to 1400 plus. Tested in NEF. Shot one case 15 times
and still going strong, tight primer, with loads running about
20- 24,000 psi.I have pics of cases soon, and we also will
test these brass ones and 3.5" plastic in 12ga Encore
Here is picture of RMC 3.5" cases with variety of slugs,
locked on wad slugs and sabots. There are 3 of our long cases
in back for comparison. The RMC turned cases have shotgun
primer. Case # 4 has 437gr slug in BPI SABOT( finally hard sabots
in 12ga for reloading), #5 437gr Brenekke KO slug, #6 540gr
Hammerhead slug, #7 600gr Dixie hard slug, #8 RG's 715gr
jacketed, #9 750gr solid brass. Ed
Here is picture of a 12ga hard discarding sabot you can get
for reloading, the BPI. From Ballistic products. In picture
is sabot with a 437gr Hornady Great Plains 50cal slug I put
in it. Also the 410 gr and 385gr Great Plains work.
Finally able to load your own instead of paying 3-5 bucks
each for loaded rounds.You can use the 500 S&W bullets also
as well as shorter 50 cal blackpowder slugs... Ed
Been testing the Encore with the Nef loads. Barrel breech is
one inch same as muzzle, where the NEF is 1.200".
It has dovetails cut out in bottom of the barrel for
the nuts for the forearm screws. ... At the bottom of dove tail
there is only .060" thickness. Before reaming had back one fill
welded as it was where the taper for the forcing cone ended up
with 3.5" chamber. I load it with 10 gr less powder than the NEF
on all different slugs and weights. Like the BPI sabot in 3.5"
plastic in NEF, 437 gr slug, 120gr 4227, 2400 fps, and in Encore
110gr 4227, 2270 fps. In 3.5" RMC brass case, same sabot/slug
in NEF 140gr 4227, 2600+ fps,Encore 130gr 4227, 2500.
The Encore is now 12 lbs, with hollow in butt and recesses in
forearm with lead shot.In pic you see NEF And Encore with RMC
brass cases started in chambers. Ed
See what's possible, original Savage 210 action/stock
the one I have our long case in. You can lengthen
magazine in the plastic stock for up to 3.5" RMC brass
cases, also 3.5" plastic cases. And you can open up
bottom of the action to match, and the other things
I did on the port, bolt travel, etc to feed cases.
I did mine with heavy wood stock in singleshot.
Using original plastic stock you weight the hollow butt.
Trigger assembly on these is back to leave space for this.
In picture you see stock original and stock mag longer.
Second picture is a 3.5" brass case and slug overall
length 3.7", in longer magazine. Brett in MN, who did this
first used the regular follower and mag spring ok,
it feeds ok for him. .. Ed
Info to help loading BPI sabots in plastic,ok to use plastic
overwad over powder, but should use cardboard card and
nitro wads above that below the BPI sabot. Sabot doesn't
tear up and accuracy much better. Personally I use
cards over powder and nitro wads, And with used cases
roll crimping onto the thin edge of sabot is uneven, so with
my used cases I set the sabot and slug to right height and
just redo the 6 point star crimp real hard, and the middle of
all the crimp sectors set right on the flat nose of the slug
in the sabot. I also do the same with RG's 715gr hollowpoint
with the crimp sectors right on the hollowpoint in used cases.
Roll crimping holds RG's slug in ok but its taper of the ogive and
smoothness it doesn't open crimp all the way around when
fired. The star crimp set slug at same height so you can get
the same amount of powder. With RMC brass these are not
problems but with brass to get good feeding from mag rounding
front edge of mouth helps. Sectioned picture of RMC on right
next to our long original case to show how well it is built
thick and strong. One of cases has 20 firings, still good..Ed
What others are doing hopping up loads and experimenting.
Brett in MN uses a Mossy 835 12ga smoothbore turkey gun, but
it is backbored 10ga size all the way out to end and has 10ga size
choke, and he uses 12ga AQ 441gr slug with locked on basewad, from
BPI. Using top rib bead sight only he can hit a pail 5 times in a row at
70 yds.Amazing accuracy for overbored barrel. He uses BPI X12X seal
plastic wad, two 1/4" white felt wads, thin card then the AQ slug,
with 65gr of Longshot getting 2200 fps. 3.5" new cases with
roll crimp.......I asked him check it with a scope on it sometime.
NFG from Greybeard and Shotgunworld with pump Mossy and 18.5"
with slug barrel. He gets a 525gr Lyman over 1800 fps with
80gr of 4759/4227 powder. Hard alloy mix Lyman and shot one through
17" of pine. Shown in the pic below it mushroomed to .800" and only
lost 8gr weight. It is a wasp waisted slug that is shot from a 12ga
regular WW12 shotcup. The skirt of the slug collapsed into the underside
of the nose. Many guys say that these are as accurate as most
other stuff used. He used 3" plastic, PGS wad over powder and
WW12 wadcup with slug it. He cuts wadcup petals back to length
of the Lyman.In pic on left you see the Lymans with hollowbase up
and the shape of it when starting out.
Ok I am going to get Lymans to test and Longshot to test.
Got to see if the Longshot will get further up in velocity
than Blue Dot. Ed
Here is a Savage 210 with bottom of action opened up
toward the back, to take cases with 3.5" overall length.
Slug Warrior on Shotgun World did it. Is similiar job the
Brett in MN did, but he made his opening 3.7". I measured
mine and they can be opened to 3.95". They also milled
the rim guides back for controlling case feeding on longer
cases.Rim guides are angled in from the sides of the opening
toward back. This work on the stock/action can be done in a
mill or good drill press. To use 3.5" plastic the opening on
the action and magazine needs 3.25", for 3.0" brass if long loaded
3.5", if 3.5" brass about 3.7", if 3.5" brass long loaded, 3.95".
By long loaded I mean a slug like the Dixie 600gr that protrudes
up to .4"...Ed
We get asked about putting brakes on the NEF Ultra.
There is the concept called the internal brake that works
nearly as good as expansion brake, with less back noise.
Rob on AR did a couple with bunch of holes in the barrel
in the end with the last 1.5" bored out .025" where holes
go. Also many want more velocity in NEf and I added on
a barrel section to mine. Combining Ideas we add smooth
9" section of bore extension, that is same as groove diameter
and 1.5" end of that for internal brake. Eight 1/8" holes
top and same 45 degees to each side.And we have over
a 100 fps in velocity gain. And with card or wad behind load
it will seal pressure going from rifled section to smooth.
And these types of holes won't bother wads or sabots.
My extension is a foot longer and gets 150 fps extra.
No need for brake in mine as the gun is 17 lbs with extra bbl.
Here is Rob's two he fixed up, and is shooting.He has
them reamed out longer for long 3.85" case, weight added.Ed
Here is a picture of porting holes in a 10ga NEF
heavy long smooth barrel. Bbl 30" and 1.080" muzzle
diameter behind the screw in choke area. This come
with slightly extended screw in choke and is first
10ga with long barrel as heavy as my NEF 12ga FH
short barrel was.. OR the short NEF 10 gauges
with heavy barrel..It came with full and mod chokes.
The other 10ga I tested earlier, only .960" at muzzle.
I cut choke off and put it back in leaving the barrel
an open bore for slugs and leaving an area 1.2" long
for an internal brake to drill all the holes in like
Rob did with NEFs in his picture. Now the 1.2" long
area where holes are is bigger than needed for 10 ga
so a reamer in the making will solve that and solve a
major big bore project for me and others who asked
me about using the short NEF 10ga for upgrade, which
I didn't encourage putting all that work on a short
barrel gun, with the amounts of powder that will be
burnt in....are you ready.......THE 8GA FH.......
I have 8ga FH loads tested in reworked Enfield.....Ed
More info on the heavy barreled gun we plan on
making 8 gauge from. Nef SB2 103, 30" barrel,
regular stock. 220 bucks. 100 bucks for shop to
ream out to 8 ga smoothbore. Needs the 80 dollar
thumbhole stock. Nice deal for a modern 8ga, using
heavy duty plastic 3.3" long cases. I fired 6-8000
ft lb loads in one I made on Enfield, 4 times reloaded
without resizing cases.
Here is other project suggested by Boomie
on the AR big bore forum, the 16GA FH.
Cases made by me from bmg brass. Took 5 swagings, and
two turnings on my case spinner lathe.Two Annealings
Got couple cases made, in picture our 3.5" case and factory
16ga plastic case slug load. I'm getting test gun working
now and as for a supply of cases you all will have to
get with RMC if you want to rechamber a 16ga..Ed
Here is picture of my NEF 12GA FH as it is now,
A while back I got tired of short barrel and
added a foot on to it. Used breech end of left over
Savage and a sleeve. Lined up rifling and it has
same twist and number of rifling. Hard way to do
it. No need for rifling, or extra line up work.
Run many loads and it adds 150 fps with VV110,
4759, and 4227 powders. Adds about a 100 with
Blue Dot, and HS 7.
Next one will be done different and easier.
Next one will be a smoothbore add on piece of
groove diameter, 10-12 inches long, make it one
piece, 1 or 1 1/16" threads,about 1.2" diameter.
Threaded 1.5" long on original barrel, and into
add on piece, and will look like a brake and you
could put in internal brake in the end.Ed
Here is picture Stevens Revelation 350 16ga
now a 16GA FH. It got a 385 gr to 2000,
which is good for gun without a real heavy
barrel. I lengthened chamber for the
3.5" brass cases pictured that I made from
BMG brass. Anyone doing this can have cases
made by RMC. Gun is weighted to 11 lbs.
Action can handle more if barrel heavier. Ed
Here is picture of the bolt for my big gun, the 700HE.
It is holding a 700HE long case. The caseholder extraction system
can headspace a BMG rimless case,no belt, so you could
put on a 12ga barrel, straighten case more, from .700 to .729"
and have the rimless 12ga. Could straighten case for a
.750" bore, even to 10ga(.775") with a little thinning of the
top one inch of the case. Experimenting is interesting
to say the least. 700 slugs in pic are 1000gr Woodleigh,
1000gr PA, 825gr Copperhead Custom(CC), 770gr FP CC,
1000gr HP CC, 825gr HP CC..Ed
There is a new heavy barreled rifled slug gun out,
the Rossi Model S12 1230S. It will handle our heavier
loads like the NEF. And it can have chamber lengthened
for 3.5" plastic and RMC brass 12ga cases. Ed
The BPI sabot is tending toward small diameter.
With a .512" slug it measures . 727"---So I run slug
into die and reduced it .020". It is lead, swaged easy.
Shot a BPI sabot with 385gr Great plains slug in 700HE
great big gun pictured above. That Great plains slug
was reduced .020". With 300gr of super fast ball
powder blend in 3.85" case got over 4500.
Using slugs with locked on bases and RG's hollowbase
jacketed slug in 3.5" RMC brass cases in the 1887
Win levergun. RG's 670 gr HB- 2500 . Brenekke KO
435gr- 2700, Lightfield 460 gr- 2600 . Even got
a 385gr in BPI sabot to target straight.Levergun has
34" smooth barrel and with chamber for 3.5" long
cases it is run as singleshot. Barrel is a tight smoothbore
going from .726" to .722". Took out lifter and other
stuff and put in a bottom style extractor I built that
is operated by the lever at bottom of opening
stroke. Then take cases out with fingers, thus able to
handle long cases in a short action.Makes a real old timey,
neat looking, single shot blaster. Also have testing all done
and loads set for 12ga Encore. It is set up for 3.5" plastic
and brass cases for strong loads. I like to sell it to someone
who likes the style. If interested contact me.Ed
Before I posted about testing a NEF in 10ga with
a medium heavy barrel. The newer one is better.
It is the one I showed the ported barrel previously.
I did some 10ga FH testing in that newer, real
heavy barreled, NEF 10ga, that is going to soon be an
8GA FH, after reaming out. The internal brake set up
on the end as shown in picture above works great.
It stopped all of the muzzle rise and cut recoil
Gun now is 14 lbs and has thumbhole stock.
Top load with 3.5" plastic case, 765gr slug,
135gr of 4227, 2200 fps, 8200 ft lbs.Ed
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
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
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
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
