12GA rifle From Hell--

[hubel458]

Here is information and reason for keeping and milling
the rim guides back for controlling case feeding on longer
cases.Rim guides are angled in from the sides of the opening
toward back. As the bolt pushes top case in the mag forward the
back of case and rim comes to where the tapers widen out so
the case then slides up in front of the bolt.I'm fixing up my
2nd Savage I have set up for my second 700H 3.25" belted case.
Just to see how it will work and along with other guys
doing it, get the info out to people.
This work on the stock/action can be done in a vertical
mill or good drill press. To use 3.5" plastic the opening on
the action and magazine needs 3.25", for 2.875"" brass 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".The 730 gr flat wide nose slug protrudes 1/8".
You also have to widen and smooth the ramp going into the
front bridge so case lifts smoothly on the way into chamber.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

[hubel458]

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

[hubel458]

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

[hubel458]

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

[RagingBullPa]

can it be converted for concealed carry, it would make a heck of an assault weapon, but that would be more fodder for Osama Obama and his Clique of anti-gun rejects, to which you can add Caroline Kennedy to

[hubel458]

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

[RagingBullPa]

are these puppies legal in all states, you know New Jersey and New York , and Massachusetts most likely not i believe they are some of the worst as far as gun regs go , but there are probably worse , its a shame too such a nice piece of hardware

[hubel458]

Wherever they have deer/hog/etc hunting allowing
shotgun calibers, rifled barrels are legal on any that
I know of. Here in MI and Midwest rifled is ok.
As far as power, there is no limit I know of on
what power a shotgun caliber puts out.Ed

[hubel458]

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

generates a bit over 3000ftlbs of muzzle energy but falls off dramatically because of lack of ballistic coeficient properties and the accuracy depends on the rifling but it isn't impressive to me at all compared to the rifles i own and shoot, but it would be nice to say i own one just for conversation and the ooo's and aaaahs heard when you pull it out at the local range oops forgot can't shoot shotguns or slugguns at a public game commission range unless it is designated for it in pennsylvania most are but some aren't, and many people are just being idiots would cry and complain anyway , but it would be the center of attention

[hubel458]

If you can load to get 50-100% more energy, helping
for better kills on deer/hogs, and accuracy(not 1000 yd kind)
gets game at 125 yds, and speed falls off fast at longer
ranges for safety in crowded, built up areas, you have
accomplished what the shotgun only hunting rules were
set up for. Safety. But yet hunter adds to that
better kills. Around here the crowded/built up areas have
biggest numbers by far of deer. Ed

[RagingBullPa]

just plain common sense not safety , you don't need a cannon to shoot deer they can be killed with a bowand arrow or atlatl, marksmanship thats the key , best shots i know are pennsylvania woodchuck hunters or several of the long range shooters from my area right here in northeastpa, in texas caliber of choice is a224caliber texas trophy hunter round, marksmanship kills , singlesnipers put the fear of God into entire companies with Markmanship, but i agree for close encounters and for safety the urbanites should use the sluggun i wouldn't want one of them guys taking a pot shot at me especially if i was traveling through A ChicagoIllinois suburb with my truck with McCain - Palin Stickers on it that i forgot to take off
