Re: 585 HE -- Barrels of Cases --

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.







Here is picture of 585HE with 700gr HP CEB bullet and 750 gr
wide meplat CEB bullet..Ed

Re: 585 HE -- Barrels of Cases --

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.



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.
