Here is picture of our NEF 12ga FH with Hogue Compstock. It has the
recoiling cam and springs in the hollow butt plus some weght,

Here is a variety of slugs and bullets that fit in the 12ga dangerous
game slug, lock on sabot. BPI sells that DG slug.

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.

And speaking of singleshots a fellow in the Yukon is
just finishing up one in a Ruger #1.And the 24hr Campfire
forum has over a million views of this thread, ..ED

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

Sorry to be away so long, health, getting old, and interruptions.
Here is picture of a lightweight Barnes bullet in 24ga FH.
Guys cut the back off of 750gr bullet off to get 500gr weight.

Image

Here is picture 58 cal Minie slug that's little long on the side for our 12ga
sabot, with the front of the slug above the grooves swaged to fit in
sabot. The swaged front third of the slug fits next to the internal ridge in
sabot and the sabot doesn't bulge out.Just run front into a die
and punch it back out.

And some info about 12ga FH and other hopped up shotgun slug loads,
You know we like to use the rifle, IE slower than shotgun, powders.
We like to use IMR 4759 for some loads and RE17 for others where
we have room for larger charges. Those two powders are ignited ok in large
diameter cases like 12ga, 10ga, 16ga, etc, without needing BMG primers.
But we have always been looking for easy to ignite powders of the RE17
type, when cold, that has a speed between IMR 4759 and the RE17.
RE17 uses different process to put the deterrents in the powder to control
speeds, which allows much easier ignition, compared to big majority of rifle
powders with all the deterrent on the outside.

There are some out there made by Nitrochemie Switzerland, who makes
RE17, RE26, RE33, etc, for Alliant. It's the ' RELOAD SWISS' brand available
for those in UK and Europe, They are called RS 40, about same speed
as RE12, RS 50 & 52, same speed as RE15, RE60 & 62 same as RE17.
Also one ' Vihta Vouri ' powder called TR140 available over there,
that Nitrochemie made..

Many guys can't get IMR 4759 anymore, some can't get RE17.
I'd like to get some of RS 40-50-52 powders or V V TR140
into the states, would really be great help for hairy slug load work.
And guys in UK/EU now can load some real hairy, slow powder, slug loads,
even though not having IMR 4759....Ed
