action. Real nice. In picture is along brass 12ga case with one
of Rob's 2000gr bore rider, solid, streamlined slugs. Ed
finally in a bmg size action. It is barrel
I locked onto an I-beam and got testing and
load developement done over the last couple
years. Max load about 23,000 ft lbs.
It weighs 27 lbs, laminated thumbhole stock,
a max size pad, weighted butt, a reinforced
wrist, recoil barrel ring on front of stock.Ed
that would handle out 12GA FH and my 700HE.
That outside hammer looks great. From a magazine
article in Very High Power...Ed
this fall, It is 12ga bore rider design Body is Aluminum, and it
will have a heavy 50 cal insert in the nose made from tungsten
or similiar metals. In the picture he put a 50 cal bullet in for
show. The insert in the nose will be flush with front of the
AL carrier. It should be stable at slow twists and if built
with back and front same diameter stable in smoothbores.
The long lighter tail-end compared to heavy nose insert
will make it stable. Same principle Brenekke uses. This idea
is being explored to try to get superior penetration
from 12ga, with heavy, hard insert in the nose.Ed
that I got rigged up on an action and stock.
Side view shows action with a aperture sight I
rigged up. Also cases. On left is 700H 3.25" case.
Center my 700HE, what the gun in picture has now.
Good for nearly 23,000 ft lbs, we attained in
a work up in testing with the barrel as a test
barrel with screw on testing receiver....Ed
is aluminum, it has a heavy tungsten carbide insert in the
nose. The TC in the nose is about 5 times denser than AL.
Total length is 2.35 inches, weight about 950 gr. The .75" long
insert a real tight type fit. Heat AL, put in insert, cools, locks on.
It is fairly streamlined, yet has wide meplat for penetration
in game. Flat points penetrate straighter in game.
It is hollow inside in the back, behind insert which puts the
center of gravity way up front, it should fly straight even from
a smoothbore. They are fast to make and material
less expense than copper.In pic is a copper and a brass 600
cal slugs for comparison. Dart/slug on right has insert.Ed
ones RG Henson sent. Jacketed 12ga. 715gr hollowpoints,
on the right and in front a jkt 675gr hollowbase.
RG's number 1-770-366-4846. These will be great for
shorter plastic and brass cases as well as long cases.
Other slugs in pic, in the back, left to right
Foster 436gr- Dixie 600gr- 750gr brass- my 750gr hollowbase
brass, and a hollowpoint I put a lightweight filler in the nose
for streamlining..Ed
jacketed ones. If interested in the hp one above
contact him at number above. He has to do a bunch
of them to get ahead to do others.And they will be
a fantastic deer, hog, bear slug. He is in Georgia.
Also, any of you who might want some of the 12GA FH
brass cases made from BMG brass, we have the fellow who
had the idea about the 12GA FH first, Rob on AR forum,
is planning on making them. He has got the machines to do
it now, that we didn't have before. Let me know how many
you are interested in getting, so he can plan and figure
the best price. He has a bunch of BMG cases to start with,
he and I have places to get more.I'm posting this all over.Ed
With 30 inch barrel, long brass 3.85" case, big primer.
Slightly hairy load 290gr RL22--2700 fps. Shot moderate load
of 300gr W-860 -- 2400 fps for 3 shot group of 3" at 50
yards with my bad eyes and peep sights. They shoot nice, they go
into target straight.. Other nice thing the price from RG,
for customers getting in on his first run, $1.25 plus shipping.
That is less than half of what other big bore jkt bullets cost.
Call him for some great slugs. They are great like
the Dixie slugs. Ed
A regular BMG case on the left, and
a straight BMG case on the right, and it
CAME FROM THE MANUFACTURER THAT WAY.
It is primer cartridge for large guns and howitzers.
It is used in those guns/cannons that have powder in big bags.
It is filled with powder and inserted into cannon breach and
when fired sets off the larger charge. On some cannon breaches
they have an automatic feed for these with a huge 40 round
drum magazine. This on is marked IVI 89 C67. IVI is Canadian.
On these breaches it is held by collet fingers for head space
and for ejection.
Ok, there are many thousands more of these out there than the
PROP cases I showed before. We need to find few barrels of these
and have Rob, etal, put on rims.... no annealing.....no fireforming,
just slight resize to 12GA FH. Please help if you know of any.
They would save so much work and time..And even though fired
the bases are perfectly straight, another plus.....Ed
loads.First are 2.75" and 3" factory foster slugs\ for
comparison. 3rd is jkt HP in 3.5" plastic case, 4th in a
3" brass RMC case. 5th in a 3.5" brass case with small
primer, 6th in our long brass 3.85" case, big primer.
Top hairy load in long case in Savage, 2900..Ed
the 715 gr jacketed slugs, the 3rd and 4th ones.
They both have same 90gr of 4227, same number of
wads, shoot at 1700 in 24" NEF barrel. 3rd plastic is
3.5" case, the 4th brass is a 3" RMC. Both have shotgun
primers.The 5th longer case is a 3.5" strong
brass one I made from a PROP case, and when I put
in primer bushing, I set it up for shotgun primer. I
will test it with 4227 powder, 600gr and 715 gr slugs.
Also in a couple months Rob, who's idea the 12GA FH
was will be able to deliver the super strong 12GA FH
cases made from BMG brass. And the they will be
headstamped, all done by his CNC machine.Ed
A 14.5 pound Ulti-Mag. The hollow part of the butt is filled with about 5.5 lbs of lead shot and epoxy. Has 4X Sightron in QRW rings. Do 3.5" plastic hulls with the Darwin in it first. It balances on the trigger. Loading the magazine with 4 and one up the spout will add about 1.25 pounds if the 5 rounds are "Darwins," and move the balance point to the front of the triggerguard.
It is heavier rifled 24" chromoly alloy barrel.
Brett in MN has Mossy 835, only with smoothbore barrel and gets
1oz finned plastic tail Ballistic Products slug to 2300 fps,
using shotgun powder.Ed
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
powder.Ed
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
Prohunter..Ed
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
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
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
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.
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. MN fellow who did this
first used the regular follower and mag spring ok .. Ed
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
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
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. Ed
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
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
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
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
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
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
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
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
or are they pretty much like a .950 JDJ... more bang for more buck.
I so far have read through and seen a lot of pretty pictures and a lot of statistics but really haven't gotta a grasp of what these monsters would be good for, that is why i asked why...
And many shotgun only, restricted by law, guys are
using hopped up slug loads for deer and hogs.
Couple guys plan on using long case chambered
guns in Africa.It gets guys big bores without
spending 10- 15 grand.
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.Ed
You can get a Sav 210, put my 700H in it,like I did
and with cost of heavy barrel, stockwork, etc
and be shooting with reloading stuff and cases
included for 1500 bucks.You can lengthen chamber on
a NEF Ultra slug gun and have a 12GA FH for
800 bucks- cases, reloading stuff, etc ready to
go hunting or busting big pails of water.The thrill
of 12,000 ft lb load in the SAvage is like driving
a dragcar for a 7 second 1/4 mile.Ed
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.
I 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
fit in a 20ga shotcup for 20 ga slug hunters, works perfect
in the 28GA FH brass case. It is a hollowbases hourglass
shaped 362 gr slug. No wadcups or wads needed, loaded
right on powder. It is the slug you buy the molds to cast
your own or you can buy them from guys who cast for
sale. I use slow rifle powders in case so no air space,
they fill to the slugs. I got 2900 with moderate case
expansion and it hits target straight on, from a smooth
28ga heavy barrel on 695 Mossberg bolt action.
Other new info on primers. Some of the guns can't have the
firing pins or hammers beefed up easy like my Enfields
With some magnum primers with hard cups you get delayed
ignition if hammer doesn't have perfect hit and high strength.
One test with a small diameter case/bore that any primer will
ignite slow powders fine with good firing pin spring would
show delayed ignition with shotgun battery cup style 209
CCI Mag and 209 Federal Mag primers, and when I tested them
in cases with just the primers, they only put in a small dent
when they fired, but WIN 209, REM 209, RWS 209(used in
Brenekkes, Lightfields, Hastings), dented in much more when
firing just the primer. And with the smaller bore you had fire out
the end of the barrel, so you could compare primer strength
visually. The REM 209 was as good or better than CCI and FED
209 Mag Primers. The WIN and RWS was close behind. We put
the REM in same case/gun where that we had delayed ignition
and it fired instantly, no delay. The two mag primer brands have
the primer insert in cup rounded a lot and little harder metal,
and the other 3 metal cup insert is almost flat and slightly
softer. It is easier to get a better more solid strike and dent.
I always figured mag primers were best in our hopped
up shotgun loads but not anymore. It took a while but I finally got
everything around for proper test. Hopped up loads(regular also)
we have talked about, use REM 209, where the firing pins
and hammers can't be strengthened. Even loads with Longshot,
Blue Dot, Steel, HS6-7, etc.
Hope this helps.....ED
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
