10GA FH info.Fed factory hollowbase slug is .025" smaller than
10ga bore. I bumped it up to the .775" size, by expanding
hollow base. With 7383 that gave another 150 fps.Fast starting
shotgun powders expand base better than much slower 7383.
The Federal factory load has 120gr of wads/seals about 1.4"
long. Better to replace with much more slower powder,
getting better velocity, still at low shotgun pressures.Ed

Look real close at the bases of these
cases. What do you see. Comments...Ed

Rings on the first two?

Correct- You get the cigar. Those
are 12GA FH we(Rob,John,myself)
built,or ""invented"" on the left.
Nothing is ever new I guess.The ones on
the right may solve source problem.Ed

Threaded case adapters or TCA's!-Rob

Giving a 16 year old a cigar? Come on...

And the ones on the right are not turned
cases either but high strength drawn
cases.Ed

Here goes. I was going to have John do a bunch
of rims on 12GA FH cases from my supply of brass
like before. Well he sold business couple weeks ago and
is going to hunt and fish, and other fun stuff.
Hence the picture above of those cases. The three on
right appear to be drawn high strength cases.I got them
fired and when resized in my 12GA FH dies they are exactly
same as ones we built.And the rim is tough like drawn case
as it didn't bend like turned rims coming out of press.
They after sizing are 3.850-3.860" long, my chamber is 3.900"

They have a long bmg diameter electric primer, like an oversize
shotgun battery cup primer. They may be a source for other
12GA FH guys wanting to build, but can't get brass easy.

You've seen my postings on the 8ga kiln guns, well different
companies have versions that are used for bomb disruptors,
for disabling bombs, IEDs, etc. They use short heavy barrel
mounted on tripods, wheeled robots, trailers etc. They fire
them remotely, with different projectiles.They are just little
cannons like the kiln guns. A lot of them are
12ga 3.5" plastic case operated with energies up to the top
3.5" load I listed earlier in the thread, 5800-6000 ft lbs.
Another company has 3.5" plastic wit over 9000 ft lbs.
These cannons have no extractors, they use knock out rod.
So the 25k pressures don't matter, they hammer plastic ones out.
One company called Proparms uses this brass case that santa sent
me three of. There are many hundreds of bomb squads operated by
police, fire dept, FBI, ATF, state homeland security,in N America
with these little cannons and company doesn't take back cases
for reloading.Also used all over the world even by military.
That company calls them their 20 mm Neutrex. Please talk to
your fire, police, etc friends and see if we all can round up
a bunch.Has to be thousands empties out there as on the net
I read of them getting used a lot and practiced with, much
more than live fire. These are not state secrets as these
disruptors as they are called are all common knowledge
if you know what to google. These brass ones been
around for 20 years I hear,and in UK they used little
cannon deals to diffuse, blowup, blow apart
and disarm bombs since the 60s. There they are called
pigstickers....interesting!!!!...Ed

In 10GA NEF 110gr 4227 got 765gr slug
to 1800, ejected ok. If it was a really
heavy barrel it could do more.Using the
7383 surplus at 150 gr, don't even have
to resize to fire 3 times. The 28GA FH
done and testing in next couple weeks.Ed

Fired 28GA FH-- Cases extract easy.--It is
in bolt action Enfield. With 550gr jkt slug,
full load 150 gr of WC-860, got 1900 fps.
This will be slowest load and powder.
In picture is 3.25" brass 28ga cases, regular
28ga plastic case, jkt slugs, a 458Win
for comparison.Regular cases work also.Ed

28ga cases are made by Rocky Mtn Cartridge,
Barrel is rifled with 4 grooves, 1-22 twist.
You could do one on Savage 210.Another
shotgun bolt action that would handle it
with little work, heavy barrel, is the
395-495-595-695 bolt action Mossberg.
Just show that 28GA FH isn't puny, here is
picture of it next to a 505 Gibbs.Ed

its "unheard" of today ...

Ed!! Are you using a solar flare for a strobe in your photos or what?!?!? You're killing us! If that's a film camera try using a blue filter to neutralize all that yellow light.

Cases look good. What does RMC charge for those cases?? Let me know if you need a short run of 28 GA slugs.

RNS has a variety of slugs that I think
I'm going to try a couple of later when
I redo the backstop.Got to help him use them
up. Only use softs and cast now.The
cases were 5 bucks each, price of
brass going up may be more now.
The camera is juat a digital computer one
and we use flood lamps and neon lights.
No blue filters on it.Ed

Here is picture and info on Royal
Arms' site for hopped up 12ga loads,
used in little cannons for bomb work.
Anyone got any of these fired that I could inspect to see how they are built.ED

Here is picture of the new Ithaca rifled barrel
slug gun for the pumpgun guys. Quality,over
1100 bucks; They'll be swamped with orders.
This one willl handle our heavy plastic case
loads and hot saboted loads. Ed

I like the Savage 210 so I'm putting
a 700 barrel on one and chambering for
my 700H 3.25 case. Working on it now.
Should get the same energy levels as
the 12GA From Hell case in same action.
In pic is 700H case in the action. Ed

Did little testing of 28GA FH between
storms. Best powder so far to keep pressures
down, and good velocity with turned cases
is RL-25. 140 gr -- 2100 with 550 gr
bullet. Very good energy for 28 ga,
5400 ft lbs. And cases fall out.No base expansion.
I had it faster, but the base of turned cases
expand too much just ahead of rim, even though
they extract very easy.Ed

impressive

Rob

I see you are from Vegas

I am in town for the SHOT show, but would lve too see that monster,

Please give me a call USA Mob 8178051839

Walter- What is your backup gun? I know if
you see Rob's you will like it.Ed

Hello

At the moment a 450 Rigby

But I know this is going too blow my mind

28GA FH research. Guy on other forum suggested using 54cal
rifled barrels for 28ga as they are easy to get. I looked into
it and did some testing. It is ok as long as you keep bullet
about 400gr as most 54cal barrels are not super alloy.
And everyone with 28ga wants slugs and there is no slug loads
from factory, and to reload the heavier bullets we shouldn't use
these barrels. But there are couple dozen 54cal bullets out there
stocked all over the gunstore shelves, in weights from 300 to
450 gr. There are heavier but for 28GA FH on deer 400gr is
graet. I tested the 405 gr copper plated Powerbelt brand, with
velocities from 2300 to 2800 plus fps. That's 6500 ft lbs.
The 54cal slugs load tight in the RMC 3.25" 28ga case fine by
sizing top a little tighter. Bullet obturates to fit .550 bore
as bullet is hitting target straight. A lot of 54cal barrels
go from 530 to 560. 54cal slugs range from .534 to .560"
There are different sizes of 28ga barrels and chokes,
so some where there is lighter 54cal slug that fits..
And with light slugs the pressure limits with the MRC brass
match top muzzle loading pressures, so these barrels will work.
And great thing is the 54cal barrel guys ain't allergic
to making long barrels. I've shot one MRC case 15 times and
still going strong...Ed

28GA FH testing. 405 gr in 2.75" plastic case
got 1400. Tested the Great Plains 54cal
lubed slug, runs from 2200 to 2700. It is
by Hornady and its front band actually measures
.550" and hollowbase. They hit target straight. Got a bunch of 415gr hollowbase coming that
are 548" from Dixie Gunworks. Only 26 cents each. All will work in plastic or long brass
case. I found another .550 bbl and coming, and
it will go on a Mossberg 12ga bolt action
for the second 28GA FH to test.. Ed

Tested the 415 gr hollowbase slugs in 28GA FH long
brass case. These are ones that Dixie Gunworks sell
that they call their Sharps .548" slug. They all run
about .008 bigger than that so they make perfect tight
fit for .550" barrel, and I used a good lube on them
in the grooves. They are a little harder alloy slug than
the Powerbelts or Great Plains The 28ga shellholder
for our Lee, Lyman, Rcbs presses , we use, is from
RCBS for regular metallic press rams. For 28ga dies
Hollywood made some for metallic presses.Also for
sizing for bottom 2/3 of the brass case you can cut
top off of the 500J die.The slower powder loads don't
even have to have the bottom half sized, which
is great for a turned case. If we had drawn brass cases
we could get 11,000 ft lbs, in the Enfield, which we
don't really need for deer. 4-6000 ft lbs ok/deer ..Ed

How similar is this round to the .729 Jongman's?

Damn Ed,are you shooting them in the hoof?
Hit em anywhere else and there ain't nothing to eat.

Roger QSL

With the Jongmans they put a small shoulder
on BMG case and used 12ga size bore.
And minimal taper to the sides to shoulder.
On our 12ga From Hell we put a rim on BMG
case and left sides straight. More taper to the sides which makes for easy extraction
if you run high pressures. Both cases are
full length. My 700HE has a belt, straight
sides, and .700" bore. It is I feel the
best of these or any other in that range.

We will shoot them in the tail. I did that
once with my 458HE, 400gr at 3200 and tail,
the base of the tailbone came off, killed
instantly, like down as hit by a freight train.Never wiggled. And upset bullet hit
second deer through lungs/heart with same
results.That was one I aimed at.I don't
like to hunt, wound and track....
I like to shoot and kill instantly. The
hunters in my spere figure if critter falls
within 30 yds they are as good as guys on
tv hunting shows doing similiar. Well that
is crap to me. I don't like it. Ed

I looked at the Jongmans and rejected the concept almost immediately.-Rob

Here is picture of a jacketed hollowpoint
12ga slug a fellow is going to make for us.
We hope to have tooling set up this summer we plan on. Next to it is a 600gr Dixie hardened
slug. First ones he will probably make will
be about 700-750 gr.Ed

The hollow pointed slug above can have a
light plastic/rubber nose for streamlining for
better BC, for 2-300 yard shooting.
In the 87 Win Levergun, smooth barrel,
long barrel, using brass RMC 3" cases,
1 oz Brenneke KO slug to 2700 with 4227
powder. Shotgun primer. I will be getting
some 3.5" RMC brass that he will put a special
longer corner radius in, to allow faster loads
with less case expansion and easier resizing.
Should get same smoothbore slug to 3000 and resize
easier also. With shotgun primer able to use VV110,4759,
4227, and you WON"T have to rework hammer
or firing pin to do big primers. And will be able to get
600gr Dixie slug about 2300 in a heavy rifled, with
shotgun primers. Will make things simpler for
ignition, use present hammers/firing pins springs,
and getting cases done, all ready to size and load.ED

Can I get one of these in a H&R topper with a tasco scope?

Shouldn't do the hopped up loads on the Topper
as it has the SB1 frame, you need the 12ga
Ultra Slug Gun on the SB2 alloy frame.
The Model/Part number will have SB2 in it.
And they come with scope rail. They have 3"
chambers and a smith can lengthen the
chambers to 3.5" very easy.Ed

Cool; I'm on it!
Seriously though, sounds like it would be great fun from a mounted gun from the back of a pick up truck for jack rabbits! Damn!

Big carniverous jack rabbits, and a smoothbore
second one mounted with big shot load, like a
punt gun for geese. A punt truck instead
of a punt boat.Hahah.. Ed

Yes, exactly! I like the way you think!

Santa sent me 9 more PROP cases used in little
cannons for bomb disposal. In pic, 2 on the left
are our originals, next 3 are resized PROP
cases, exactly matching ours, and then 9
to be resized. Ed

Here is picture of the Enfield bolt,
showing the 2 rear lugs I added.
The huge bolt handle base is 3rd lug.
Bolt handle needs polishing.This one
will be in the action for the 8GA FH.Ed

Here is picture of the 4 slugs I've used in
the 28GA FH load developement in the
3.25" long brass case and they
also work in the plastic cases. Ed

THE 8GA FH BELLERED TODAY. It is in Enfield I rigged with
rear locking bolt lugs. 32" barrel, tested 3.3" plastic cases.
Cases are the REM kiln gun cases. With the double cup base.
I shaved base a little so that chamber will fire these as well as
regular 8ga plastic. None of the firing today expanded base cups
at all, so they are real strong cases. Started testing to check
ignition with shotgun primers and to see if cases are any
good. Starting with a 110 gr mouse ball, wad under it, and 150 gr
of Blue Dot, about 5000 fps.. Gun didn't even recoil.Then a
410 gr one at 3000 fps, Then a 770 gr hollowbase slug in a wadcup
up to 2000 so far with 180gr of 7383. Barrel is smoothbore. 832"
bore at the muzzle. Ed
