Some guys in 12ga like to use the Magtech brass cases
but the cases being brass the sides are thinner than
plastic, and that makes loose fit in 12ga chambers.
And cases expand a lot with heavier loaded slug
loads, are harder to resize, wear out quicker.
But I found that .750 hollowbase 10ga slug fits
those cases and still chambers in regular 12ga.
chamber, it isnt a sloppy fit.

So If you have a 12ga smooth barrel with full length
backbore job, of .850" bore or bigger you could use
the Magtech brass and .850" size 10ga hollowbase slugs.
Now these .850" slugs won't go in a 12ga plastic case
and chamber in regular 12ga chamber.And you do not
fire them through 12ga regular size barrel.

Brett in MN used the a BPI AQ slugs in his full length
backbored 12ga and got fair accuracy as he said the wads
under slugs expanded a lot for a decent fit.
The 10ga slug shown in the 2.5 inch Magtech is 800 gr,
and .850" diameter. These cases will take magnum
pressure so you can get good speed, for what this short
case can hold.

It is too bad they don't make 3" and 3.5" versions.
These 2.5" cases are easier to find and much less than
others, so if needing brass ones you can rig up guns
to work with them. To build a new barreled gun in actual
12ga size, IE .729" bore, you'd make chamber to
minimum specs so cases don't over expand.
In the picture are 2 10ga slugs on right, like in the case,
and 2 12ga jacketed slugs and one 12ga lead slug left.ED

Here is the ytube URL again for our guy
shooting 585HE in his NEF----By mid summer we plan on a
pickup truck load of more 585HE cases coming in.

Here is good simple system with big hollowbase slugs to stop
the skirts from deforming, I found that dense dow foam works
good, I was using glue gun but dow foam is easier, Just cut
plugs out of foam sheet and force into the base. Make a tight
fit, use spot of glue inside, glue that is for foam....
Trim off the foam flush..In picture is 10 ga 900gr slug.

How we get good 24ga plastic seals with protusion on
top that fits up inside 58cal Minie base, same bore as 24ga
and our 585HE. I get the 24ga seal by cutting apart the BPI
24ga Brush wad, getting two seals out of each.Works great
in plastic case giving a shorter column than other seals and
wads, so we can get in enough of our 4759 for good speed.
The 24ga idea is getting nicer all the time with
the variety of cheap 58cal slugs, and good 3" brass cases,
drawn cases, we didn't have to wait to get made.
And all kind of guns we can use, bolt 395 Mossbergs, single
shots of all kinds, Autos,, pumps. bolt action Savage,
even 1887 Win and Greener MKIII, bolt action JC Higgins. .

Here is picture Khan auto we setting up 24ga FH, it is 3.5"
model, has a 12ga barrel to change with. Being 3.5" it
feeds/ejects through lengthened port 3" brass 24ga cases we
made from 577NE brass. We rework back of the bolt for
slightly longer stroke.Ed

Here is picture of 24ga cases, loads; and some slugs and seals.
Brass cases are 3", plastic cases are 2.5". Brass 3" can be loaded
to match 577NE power.

12GA FH- Hairy Shotgun/Rifle- - General Shotgun Discussion

Here is of 24ga in an 87 Win, just test gun of mine. Uses same barrels
as our 585HE, This one has slow twist for Minie bullets.Our guys
have got supply of regular and slow twist barrels.

12GA FH- Hairy Shotgun/Rifle- - General Shotgun Discussion

Here is picture of the first 585HE done and shooting in Australia.
It is owned by the poster, 'tankhunter' on the AR forums.
Built by his smith who has a reamer.
Guys there can get cases from Bertram, and there will soon be three
reamers there. There is a company there now making 585 barrels,
Allan and Grant Swan. in Redbank, Queensland.....Ed

Finally got back to forums.Been busy with 24ga FH and 585HE
and getting 585 cases made, as many as possible...

We are now working a bit with 24ga FH and here is picture
of it with our 585HE case. Both use same bullets/slugs, same
bore barrels. Main use difference, 24ga FH easy setup in break
actions and 585HE in bolt actions and falling blocks.

12GA FH- Hairy Shotgun/Rifle- - General Shotgun Discussion

Picture of non-discarding 585/24ga sabot cup I found that holds
458 bullets and slugs tight. It had hammerhead type slug in it that
was pulled out and they wouldn't stay in tight. Sabot was a loose fit
in 20ga, made for 20ga, but small, so I shrunk the bottom rib,
fits perfect, super tight, in 24ga and 585HE. Fits real tight to give
good resistance for good ignition.

12GA FH- Hairy Shotgun/Rifle- - General Shotgun Discussion

Here is another 24ga/585 sabot that holds .452" 45cal pistol
bullets. Made by Hornady for 58cal ML. With 250 gr bullet in 585
will go about mach 4.

12GA FH- Hairy Shotgun/Rifle- - General Shotgun Discussion

Here is easy way to weight plastic stocks with hollow butts, use rubber
coated computer mouse balls, weight comes out perfect without being
too heavy if using that much lead.And coating keeps them quiet, and
we hold them in with piece dense foam under butt pad....Ed

First AUS buffalo killed by 585HE. By Tankhunter with his Ruger #1.

If you use closeup on picture, you see loaded round on the buffs hide

next to the 585HE Ruger #1.... A nice heavy barreled gun..Ed

12GA FH- Hairy Shotgun/Rifle- - General Shotgun Discussion


I put the 585 in a Savage 112, lots of room lengthwise, figuring out an
extractor is a problem, but then got a look at the savage 212, the 12 ga
one with big diameter bolt and locking lugs. Its locking lugs are bigger
than the lugs in a big PH bolt action. So one day will do one
on a Savage 212, and adjusting extractor to fit no problem...Ed

Here is picture of 585HE 100 cases loaded, CEB solid nose bullets
and hollowpoints. This bullet is a turned solid with wide meplat
or wide hollowpoint. .

12GA FH- Hairy Shotgun/Rifle- - General Shotgun Discussion

Here is picture of triball loads that fellows like for deer and hogs,
and just general tear em up fun, with using BPGS seal to improve
sealing under what are heavier loads. The balls are .600" and
315gr. each. The wadcup is a TUPRW123 that Precision sells.

12GA FH- Hairy Shotgun/Rifle- - General Shotgun Discussion

I need a bunch of empty 3.5" 20ga plastic cases.


Our 585 caliber is modern bolt action continuance of the 577 Nitro
Express rimmed case, that many big game hunters like, usually
set up in double rifles. It has an interesting history, from the old 24ga
size to 577NE, to 585 Nyati with G&A picture of Ross Seyfreid
shooting one in a Ruger #1 under recoil knocking his shooting glasses
off, to the Trex of internet fame knocking guys over with recoil,
to our 585HE the strongest yet.

The 577NE is an offshoot of 24 gauge caliber paper cases, only they went
eventially to brass cases. Back in the 1860-70s, starting first with short
cases and black powder, cases built like shotgun cases, called the
577 Snider, then going to coiled brass cases, still with black powder,
then on to drawn brass cases, called 577 BP Express. then to 3"
and other longer cases with smokeless. The Snider started out with a bullet
of .570" diameter and through the progression to the 577NE bullet
diameter ended up at .585". This general bore diameter of cartridge guns
and muzzle loaders, it is really interesting on how they developed
and were used by military and then hunters over the years. The Snider
was necked down to make the 577-450 , a military round used all
over the British Empire, by the tens of millions.

Bases of both 24ga and 577NE are about the same. Now we have made a
24ga FH, a slight regression to earlier times, by taking 577NE brass, and
reducing rim diameter to 24ga specs. Two minute job. And
stamp the caseheads 24 ga.

For shotgun upgrading in power and range, It is all about increasing
the power in easy to find brass cases, stronger actions, and finding
reasonable price rifled barrels. Same barrels we found for 585, work for 24ga.
The 577NE brass we make 24ga drawn cases from, for example are
about a third the cost of 600NE brass, or getting turned 24ga cases made.
We could use 24ga thin cases but they are a pain, expand way too much,
with slug loads which makes resizing without crumpling cases a problem.

Info about the power in types of guns normally set up with 24ga FH,
break actions, bolt shotguns,etc. In thin brass 24ga case, 440gr slug
goes 1500, with about 2000 ft lbs, that's in a 2.5" Magtech brass case.
Now using the better, heavier 3" brass we got, we can increase speed
to 1750 fps increasing energy 50%, going to 2000 fps about doubles
energy. And going to 2300 which good brass holds ok, in heavy barrel
gun, gets us near 2 1/2 times the energy. About 37-40,000 psi which the
actions hold in this smaller diameter case, compared to 12 gauge size.
So makes relatively smaller bore shotgun, 24ga, with 458WIN power.
.Perfect with Minie bullets. Perfect for deer and hogs, bear, etc.

Great for slug hunting in shotgun only areas. We mark barrels 24ga
and cases 24. A decent case that is complimentary to our 585HE....Ed

Guys asking about using 585 CEB bullet in our 12ga super
sabot. Here is picture, We just took off the bottom band and couple
middle bands on the CEB and it fit perfect in our 12ga sabot,
which uses .575" slugs. Hollowpoint one pictured 700gr in the
sabot loaded in brass case. Can be used in plastic case with a
special made hollowed out long roll crimper.

12GA FH- Hairy Shotgun/Rifle- - General Shotgun Discussion

Getting some more interest in our 585HE.
An application for our 585 HE is for guys with old military 14.5mm
PTRDs, to use our case with chamber insert. In many places 14.5
cases are scarce, real expensive, as well as most 14.5mm cases
being steel are not the easiest to resize/reload. Our case sizes
like regular cases and can be easily reloaded many times.

And a PTRD with almost a 5 foot long barrel could get 650gr
spitzer bullet to about same speed the 14.5mm gets a 900 gr using
3 times as much powder. About 3300 fps. Or get a 900gr at 2800.
Great possibilities for fun shooting. For tactical use in a place
where it would be useful to reload in the operations field, where
steel cases are scarce. 100 of our cases do over 2000 reloads.

12GA FH- Hairy Shotgun/Rifle- - General Shotgun Discussion

I like Enfields to put our 585HEs in, for reasonable cost guns, the
actions once sporterized are one of the longest for long cases. .
Here is inexpensive way to fancy up the Enfield Bolt handle by
cutting the dogleg part of the old handle off and welding on
inexpensive contoured handles I found, one of which is like
Ruger 77 handle, the one on the right . Something even a novice
like me can do.....

12GA FH- Hairy Shotgun/Rifle- - General Shotgun Discussion

A lot of guys are crazy about CEB bullets. Here are light 450gr
ones in our 24ga FH. That hollowpoint can range in weight 450gr
to 700gr depending on how much we cut off the back..
The 24ga FH brass case is nice complement to our 585HE,
for shotgun only deer hunters that want a .585" caliber,
and easy to find big bore bullets.... Ed

For lightweight plinking, deer hunting, etc, in 585HE as well as 24ga FH
here is picture of 58cal Hornady sabot that holds .451/.452" light
bullets 225 to 300 gr. A way to shoot targets economically. Low recoil
but a big bang and satisfaction. A 250 gr bullet would go about
mach 4 with a top load..

12GA FH- Hairy Shotgun/Rifle- - General Shotgun Discussion

Here is what 585 bull barrel, target blank looks like, 1 5/8" OD and 32" long.
It'll go in heavy action of some kind. 4th one from the left. The one in yellow
sleave on top, is a heavy contoured one with muzzle of .980". we got a
bunch of them and so does McGowen.

12GA FH- Hairy Shotgun/Rifle- - General Shotgun Discussion


Here is picture, nice cast bullet I like for the 585HE and 24ga FH.
It is .585" diameter and 650 gr and these particular ones are a
hard lead alloy, plus they've been heatreated. They are about as
hard as copper jacketed softs pivtured. These in .575'' size would
work in our 12ga sabot..

12GA FH- Hairy Shotgun/Rifle- - General Shotgun Discussion

But to penetrate good and do great damage to game or target they
can be fairly soft lead and hollowbase like Minie Bullets. Here is picture
of timber drilled through with .585 soft lead Minie from 585HE.
Picture is the back of 6x6 timbers where Minie bullets came out.

There is couple 585 videos on Swann Gunsmithing's Facebook site;
Of our 585HE in first Ruger #1, that was done in Australia.It was set up
for the poster Tankhunter on the AR big bore forums. That gun killed the
first AUS buff, killed by a 585HE, that I posted picture of above. You can
go direct to the page and click on the videos to watch the test firings..

Here is picture our 585HE in a Montana PH action in a MPI stock, with the
style of a CZ stock and metal will be finished with a Gun Kote finish.

Here is picture of a 585HE we did in a Mauser 98 as a
singleshot test gun. We used a composite stock we
adapted to fit action. Weighted to 12 lbs.
Enfield in back, you can see it is longer.

The 12ga FH isn't the first wildcat case built on BMG brass, it was preceded by
target rounds like the necked down 338 Talbot, the cut off 700 DKT for big game,
necked down to .416 and . 458, and more, but the following one was way
before them, in my favorite rifle caliber, for .585" bullets.

One of first modern era 585 caliber wildcats, since WW2, the 575 Miller-Greiss Magnum,
was first mentioned in the fifties, It was made from BMG brass shortened to 2.70" long
and necked up from 50 cal to .585". But actually if cut off first, it would be annealed, necked
down to hold 585 bullet. Fairly sharp shoulder.

They rebated the rim quite a ways down to .618" to maybe fit 98 Mauser bolt.
Maybe used a special hogged out, reworked action. Listed as
shooting 750gr bullet about 2400 fps. It holds about 150gr of ball powder under
a 750 gr bullet, maybe little less than 3" 50cal spotter case, where our 585HE holds
180gr under a 750gr'.

We made one for experimenting on a full length BMG case.With rim left same as the base
and would need a BMG or PH sized bolt and action. I'm glad to be a big bore wildcatter,
and happy to be in the company of big bore nuts, old and new. Years ago when guys did
big wildcats on BMGs, they took what was available, full length BMGs to rework, and but
maybe back then they could have used the 3" BMG spotter case, by shortening the neck,
if they could have found couple barrels full.

But it takes a lot of work to reform and shorten cases that much like M&G, with the multiple dies,
multiple annealings, and case trimming and extreme reworking of regular rifle actions,
which is why I like our 585 case, simple and straight, any regular, long bolt action, or
falling blocks, break actions, etc, a 585 good for dozen or more heavy loadings,
and moderate loads, last forever..

For our 585HE , made it a size, actually new belted size, to fit regular size, long bolt guns,
(not BMG actions)that didn't have to be used from tripod so to speak, and could be put in a favorite
gun of many, the Ruger #1, other falling blocks, without taking metal out of the feed trough.
To get the same and/or more powder space as a cut back, really shortened, BMG case, like M&G,
wildcatted to 585, or other short cases, we made longer case and worked with guys
with a group buy, to get a factory run made. A miracle. We thank all gun nuts for the help.

Here is picture from the great site, cartridgecollector dot net, of the M&G Mag .Ed
