Had question about locking RMC cases onto
lead slugs, as they don't crimp into the
grooves well as sharp bend works thick
mouth. First I resize tight and slightly bell
mouth.Insert slugs which take a little pressure.
Then I use a die with slightly more
taper and swage the mouth into slug, like
the fit you get with bottleneck cases.
Same deal works with our long cases made
from BMG brass.Ed

Preliminary testing with VV N-110 powder shows
it works with small primers like the 4759 powder,
in plastic cases. Perfect ignition like the 4759.
Starting loads are 60 gr min like 4759 for good
ignition,600gr slug. In 2 & 3/4" plastic full load is 75gr
with card and 1/4" cushion wad.In Nef 24" bbl 1700fps.
In 3" plastic 87gr, card and 3/8" wad, 1800 plus.
In RMC brass case. 100gr, card and 1/2 wad 1900 plus.
All running same safe pressures as 4759 lab tested.
So that is two powders that are slower than shotgun
powders, and much safer to work with for regular
primers, giving at least 20% more velocity. Ed

Along with the two slower than shotgun powders, IMR 4759
and VV N110 that ignite reliably with shotgun primers,
that are easier to load for slugs, in heavy bbl can
get 20% plus more velocity, I've found another. It is
IMR 7383 $3 a lb surplus. Tested plastic 3" cases, perfect ignition with regular primers. 8 types of cases,600gr slug
starting load 100gr. Full load 140gr giving 1800 fps plus
in 24" bbl NEF.With loads halfway between start and full
didn't even have to resize to shoot again.Full load just has
a card wad under slug in 3" plastic.Wad just tight on
charge, as no extreme compression of powder needed.
Will do heavier slugs and
RMC brass cases. Ed

Tested 730g with 7383. Perfect ignition.Extracts easy.
130gr gives 1650 plus fps in 3" plastic.
Tested 800g slug with 7383 in plastic.Works good.
Have question about different cases and dies.
The RMC cases use a shotgun primer, thus they have
a real thick base. They are not a thin headed,
balloon headed case, and RMC makes sides thick
enough for regular 12ga wads.
But in a break action the 3" plastic cases
with our 4759, VV110, 7383 loads are close to RMC in
power. Can buy a hundred plastic for price of one RMC.
3.5" chamber 12ga with plastic is as good as RMC for 3"
And if I shot RMC in Savage to get more power,
which I could do as far as the firing process,
the expansion above the base, due to being a turned case
would make extraction stiff, causing extractor to
damage rim. A turned rim will not take what
a drawn one will. Rcbs set should do RMC easy.Ed

This thread is a great read. NEF also has the 20ga Ultra Slug Hunter, a rifled heavy barrel. Have you done any work on a 20ga FH? I did notice a mention of a 28ga FH.

Keep us informed. I have a better understanding of how this are developed from my reading.

hubel458 · « **Reply #65 on:** June 08, 2007, 07:32:31 AM »

Nothing on the 20 gauge. If we did we would get 3.5" brass
cases from RMC. And use some hardened lead slugs.
We tested 870gr hard slug with 7383 in 3"
plastic. Over 1500 fps in NEF short barrel.
I wish it had a longer 32" barrel..........
The folks at 50 Cal suggested we write up a
piece on the 12GA FH. Interested in what we
did to make hairy cartridge using 50 cal brass
adapted to the 12 gauge shotgun platform.
A job for Rob to do? His wild idea has been
viewed about 400,000 times in the forums
we put it in.Ed

d_hiker · « **Reply #66 on:** June 08, 2007, 09:58:14 AM »

It shows how much interest there is in the subject. And it has been an educational experience in understanding the internal workings of a firearm. I now know more about how different factors effect the pressures involved.

Again, thank you for the information.

still waiting for the 28 ga fh never sell the 12 ga fh seen them on another site going for 50+ a round I only want to be a local that is well to help this along ,would love to fire that gun someday and still want a 28 fh Your friend ................John

Found another powder that works with small
primers in plastic and RMC cases, w/600gr slug.
It is IMR 4227. Ignition perfect, same load
levels and velocities as 4759.

Powders slower than shotgun type, that ignite
properly with small primers(shotgun-lg rifle);
we found 4759, VV-110, 4227, 7383 surplus,
the latter a slow powder that also works
with real heavy slugs Ed

hubel458 · « **Reply #69 on:** July 07, 2007, 07:19:43 PM »

Pressure tested 7383 with heavy powder load.
870 gr with 128 gr of 7383-- All that could
be put in REM plastic and keep length to what
would feed from magazine of a 3" gun,
after it was roll crimped with tool in drillpress.
1513 fps-- 14700 psi. That is a slug 50%
heavier than factory Buckhammer at little
faster speed and at little less pressure.
Ignition perfect, cases fall out.
Love that $3 a lb powder.Ed

Finally able to make the
longer barrel improvement on
the 1887 12ga levergun.......
Rifled and heavy and 31"
long. After many months finally got
a barrel.Ed

hubel458 · « **Reply #71 on:** July 22, 2007, 08:45:50 AM »

With NEF. Plastic cases, roll crimped slug
in drillpress. 82gr IMR 4227 1650 fps,
with 730gr, 78 gr 4227 with 800gr, 1600.
Expansion on cases show little more pressure
as full loads of 4759 and 600gr.
Ignition perfect with small primers.
Ejects cases fine. Burns clean.
Got a GEHA bolt 12ga to put a heavier
rifled barrel on to test. Ed

Tested 870 gr in NEF with our long
brass case with big primer.I have NEF
with extra hammer spring for big primer.
Got 2000 fps and still able to extract case.
Would do little more, extractor needs
to be wider and set up positive.
Used 260gr of WC-860 and MagPro.
Could use RL-22, Rl-25, Retumbo, etc.
That's 7700 ft lbs.. I get 600 gr slug to
2300 plus in NEF, long case. so you can go
light or heavy.Ed

hubel458 · « **Reply #74 on:** August 15, 2007, 06:01:53 PM »

More testing with 4227. Greg got little over 1500 fps in
3" plastic with 870 gr slug using 74-75 gr of 4227.
I did the same. This compares to much lighter
REM Buckhammer slug, we have more speed. Almost all
the way through 5 ft bundle hardwood boards.
I have Mossy 695 as well as GEHA 12 gauge
to put heavy rifled barrels on. And my 87.
Will be checking Mossy 395
for a guy who wants to put on
a heavy barrel.Here is pic of 695 bolt action
Mossberg with dinky barrel and the heavy long
rifled barrel for it. Ed

Very cool stuff!

My interest is in the 28 and maybe even a 24 ga (.58 caliber). I'm currently "fakin' it" with .58 bullets in 28 ga brass cases.

My interests are in SxSs in these "FH" cases.

Great read. Looking forward to more.

tested in NEF 3' cases, Alliant 2400 with
small primers, Fired ok at 75 deg but when
case cooled there was majority of misfires
and squib loads. Don't reccomend it..
Here is picture of Mauser 12ga bolt action
GEHA next to a heavy barrel like I will put
on it Make a good slug gun.Ed

We tested 3.5" plastic cases in NEF, small
primers. My chamber is lengthened for our
long brass case, so they work fine.....
With 600 gr slug, 105 gr of IMR 4227,
got 2100. Same slug, 180 gr, 7383 surplus,
got 2100 fps. That's 5800 ft lbs from
plastic shotgun cases.Ed

hubel458 · « **Reply #79 on:** October 20, 2007, 06:16:18 PM »

Here is the Enfield I reamed out to feed 12 gauge and BMG
size cases. I added two rear bolt locking lugs, one the huge bolt
handle and another added that locks in rear bridge. The front lugs
still contact on their top 40 %. This is concept from earlier shown
Mauser shotgun conversions, where they were made from 98
Mausers, giving a bolt action 12ga.This one is chambered for
my belted 700H 3.25" case, as a load developement test gun.
Loads up to 825 gr at 2500 so far. Ed

What are you going to put that big 8 bore in? Enquiring minds want to know!

billy_56081 · « **Reply #84 on:** October 26, 2007, 02:08:41 PM »

I don't know what caliber that biggest one is bot I bet it started life as one of those 20mm Vulcan rounds that I fired tens of thousands of in the army.

hubel458 · « **Reply #85 on:** October 26, 2007, 06:34:08 PM »

It is the 8GA From Hell, a real cartridge. 4.3 inch long
brass case. 8 ga shorter plastic case, plan on in same chamber.
The brass kiln gun case isn't as long as mine. Where do
you find the rare 8 ga brass kiln gun cases.
Looking now for guns or actions and barrels. I make it
from 20mm Suzy brass(20mm Hispano Suiza), by putting
on a 8ga size rim and reshaping like we did 12GA FH.
We made our 4bore out of the Vulcan brass(It's fatter)...Ed

hubel458 · « **Reply #86 on:** November 05, 2007, 05:25:22 AM »

8ga, we gonna do a couple, first one a test
gun in an Enfield with rear locking lugs added.
All locking is in the rear, it is not exactly like
my 700HE one,as both lug seats gone in the
front like a Mauser 12ga shotgun.
May have a way to get barrels 'fast'---
fast being like 2 weeks, from the time I
have money to do it. And only about
150 bucks each.......Am working on it.
In pic you see long case sticking out of
the action, a couple 8ga plastic cases, a
couple of the 8ga kiln slugs, 3 oz and
hardened. Am looking for a slug built like the
Federal 10 ga one that has rounded nose and
hollow base, that fits bore tight, for smoothbore.
The barrels I am working deal on will be smoothbore.Ed

Got an 8ga barrel blank being made now,
will be here end of the week.Found this
info on plastic 8ga kiln gun loads, they
load a frangible 710gr slug at 2300-
for 8300ft lbs, load 1275gr hard slug to
1700, 8100 ft lbs. We will outdo those easy
with our non-shotgun powder loads, in
a heavy barrel. We setup an Enfield for 8ga.
In the 87 long barreled gun we will be testing
Breneke slugs. Guys are reporting good accuracy
in smooth and rifled barrels. The pictured barrel
on 87 is smooth and we will see how the
slugs in pic stand some speed.Ed

hubel458 · « **Reply #89 on:** November 30, 2007, 08:11:16 PM »

Tested 35" smooth barrel in 1887. Got couple
1 oz foster slugs over 2400, with 110gr
of 4227. 3" plastic case, regular primers.
This is a heavy barrel for that type of load,
don't do this in your 12ga skinny barrels.
The 28GA FH cases on the way.Chambering
bolt gun for it now..Ed
