585 HE --- Super Strong --

If you've followed our work in the 12ga FH thread you've seen
our 585 HE cartridge and its development. We have barrels
of cases and more coming.

We have put it in all kinds of guns, and tested it with 650gr
bullet over 3000 fps as heavy load to test the brass, and also
for lighter game like deer and hogs and target fun we found
that some of 440gr- 540gr 58cal Minie bullets work great

First picture shows it next to 505 Gibbs, it has same overall
loaded length as a Gibbs. Holds up to 190gr ball powder.

Next pic is a barrel of cases

Third representative of types of guns we have it in.Ed

We get concerns about recoil. Guns are weighted a little, thick pads,
can be ported, use moderate loads, they shoot nice...And moderate
loads still much faster than 577NE. And can be had without costing a
years pay. Most local users(only 1 in 10000 hunters go Africa) can
shoot lighter .585 Minie bullets, which load for about 95 cents each,
once you have cases. Folks can get 100 cases, dies, barrel
to put in something for 750 bucks..Ed
 
Yes it is perfect for a #1. The few #1s ever done in 577, they had
to relieve metal behind the action shoulders that breach block
rests against because of rim. Ours don't have to and the #1s
extractors I've seen work better with belted than rimmed.Ed

Case doesn't need special made shellholder, number 31 RCBS fits fine.
It is a straight belted case that holds up to 190gr of doublebase powder.
Powder need not be like charcoal, IE, really slow powder, as necked
needs. So it has effiencies of 37-39%, where necked cases are
about 29%. Here is one done in a Savage..

The loads tested at high pressures about 65,000 psi, when extracting, the
weight of the bolt after opening pulled cases out. We've fired moderate
loads in singleshots that we mono-blocked barrels into and the cases fall
out after firing. Here are couple a nice singles with 585HE in them.

Cases are made super strong, in the same factory run as the super
high pressure Cheytac cases. The base of our case is same size ahead of
belt as Cheytac/Gibbs bases. Done with same cups and draws, just uses
a different header, bunter, and sizer. Here is picture of the one we made
and the factory one sectioned showing the strong built inside corners.
These are not balloon head junk cases.

We and CH4D have die sets, Manson makes reamers, and we have some.
Reamer specs all set and the chambers made with them, the cases
extract at the highest pressures.
Here is pic of one we set with 585HE in a Greener GP.Ed

What is the parent case? If there is one...

Looks like itd be a perfect case to neck down to .375 and have a LR hammer. Probably get more MV out of that than a .375 CT.
 
I made first ones from straight, long, basic Nyati brass,
This was brass that had not been trimmed so I was able
to make a long straight belted case. There was a Nyati clone
made by GMA that I got basic cases for also.

The base of case ahead of the belt is same size as Cheytac
and Gibbs, so Bertram was able to make cases from same brass cups
and use the same tools for the case draws and just had to use
different belted header to finish cases at the end of the process.
Works out well as he doing these cups and draws steady. Ed
 
WE get asked about whether the 585HE is a DD due to being
over 50 cal, and no it is not, as we applied for and got a
sporting cartridge exemption few years ago.

First picture is base view of cases new and old. On the left is
4 new ones that come with no headstamp that I stamped,
and the 6 new ones in the middle has a 585 stamp.
We got a barrel full without stamp and guys can wildcat
them and put their own stamp on..

Second is side view with some in # 31 holders.No special
holders needed. .Notice how uniform belts are on the new
shiny ones. Dark ones are ones I made years ago.

Third is one with AP bore rider bullet in with others
behind. Maybe make a great long range target cartridge.
Got a guy setting up one with long heavy barrel for that.

wide meplat CEB bullet..Ed

In the pictures above you see the older first cases I made from Nyati
cases and other cases that were Nyati clones. These were straight basic,
long, untrimed cases, so I could get the longer case we wanted.

We get asked about the process of doing it and here is picture sketch
showing original case, a case with the start of a belt step, and finally
a case after it is swaged and sized. Note the belt diameter ends up the
same as the base diameter of the original brass. These cases we made
years ago was how we got the 585HE started and tested and some guns
done. This process can only work with original cases that have a thick
corner radius to leave plenty of thickness ahead of the belt. In doing this
process with different wildcats we have found cases that wouldn't work.

Now these cases have a diameter that works with regular bolt guns,
without extreme machining on the bolt, as opposed to 577NE and Trex.
Here is picture of a case held in a Ruger bolt, for example..

And our case is large enough capacity to get the power, without being an
oversize, soft case. Thicksided cases relative to size of the case are much
harder to harden the heads and the lower body back up to proper strength.
because of the extreme annealling needed, in the drawing
and heading operations in the manufacturing process.
Our cases are made with same cups and draws as the ultra high pressure
Cheytac cases, and our real high pressure tests show they perform with
no extraction problems.

Here is picture of a O/U I had top barrel sleeved with smooth tube, and use
the 585HE in it with lightweight, hollowbase Minie bullets. Shoots about as
accurate as foster slugs in a 12ga. Bottom barrel is 3.5" 12ga smooth.

Some more info- For guys in other countries you can get cases
from Bertram in Australia. I can send die sets. There is a guy
in AUS that has a reamer I sent him.

We have experimented with black powder type of loads and the
Minie bullets, The Minies we use are the ones measuring .585".
Also for reduced loads with lesser amounts of powder we found
that 24ga wads work perfect in the case, like in this picture.

585wads24.jpg


WE did couple guns in smooth barrel to test hollowbase Minies.
Found that they work for shot in our case. Holds 3/4 oz of shot.
Put a 24ga card on top and glue it in.

We even got one in good ole NEF, with a 585 barrel monoblocked
into it and gun weighted, with thick pad. Guy in TX got one also
and there is video on ytube-- URL below-- Ed

We have a guy who is working toward getting the 585HE cases into
Canada, for guys there to be able to get them from him..

Our case works for black powder type of loads using .585" Minie
Bullets also. Here is picture sectioned case with 4 Pyrodex 54 cal
pellets stacked behind a 440 gr Minie Bullet.Goes over 2500.
Can be loaded with 3 pellets and 24ga cushion wad.

Here is an innovation in a 585HE Falling Block we did. It's in a
one piece thumbhole rifle stock. Nice to handle and shoots heavy
loads a comfortable as a weighted bolt action gun. FBW brand.

Here is a bunch of barrels we have, the wrapped ones are slow
twist just for guys doing 585HE guns to use Minie bullets for
deer, hogs, target, and plain ole fun Using black or smokeless.

Here is picture of one being done by a guy on a big Enfield with a
nice figured Walnut stock. It is weighted and has a thick pad.
Being done African style with thick barrel and integral front sight.
You can see a bunch cases in background shelf.--Ed

Hooray the first batch 585 barrels from McGowen has got here, more
will be built.They are the regular 1 to 20 twist barrels, and we have 14
that are profiled and polished, and 3 others that are straight blanks,
1 to 20 twist. And 6 slow twist barrel blanks for guys doing mainly
Minie bullet guns, and bunch smoothbore blanks...Pics soon.

Here are couple more pictures of the gun guy is doing with nice stock.

Here is picture, 585 FBW falling block with Hogue Knoxx Compstock.
Helps reduce recoil in this lighter gun. Ed

Since you had Bertram make your brass, do you have their contact info? I can`t find an email directly to them.
