585 HE -- Cases In Production --

585 HE ---Tested 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
under bullets...

Next pic is a barrel of cases..

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

We get asked 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. Great for target fun, hogs, deer, etc... Cases
last forever. We can load to any power level we need or want.
Folks can get 100 cases, dies, barrel to put in something, 750 bucks.

Asked about #1, And perfect case for the Ruger #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 big rimmed.
Ours holds more powder, cases built for extreme pressures.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

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

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

Here is picture of the barrels from McGowen, with other barrels.
We got most of the McGowens profiled and some straight blanks.
Others we have are the slow twist and smooth...In back some
of the cases and die sets.



Here is picture of an Enfield and a BBK in Hogue recoil
reducing stocks. These stocks are the rubber coated with
the easy to grip, nice pistol grip..Have Mcgowen 26 inch barrels,
1 to 20 twist, barrels are heavy profile and taper
to .980 inch at the muzzle.



Here is a visual comparison of why I really like Enfields and
Rugers for big bore work. An Enfield on the left.... Lugs
built much stronger, simpler to put barrels in actions,
without the wall in the middle of front reciever. Easier
to shape breaches to feed big cases, so they don't hang up.
Left lug longer and forward, simpler to do bolt faces to hold
bigger cases...Ed

Here is picture of 585HE in a Montana Rifle Co. PH action.
The double stack mag for the 505 Gibbs they make works ok.
The Enfield in the Hogue stock above is done and gone.



We also had guy show us how the case can work for a
high energy subsonic, real high energy for subsonic
1600 gr at 1050 fps. 400 ft lbs. The 585HE Whisper
Anyone with some way overbore 14.9 mm necked
cases on huge actions, can make case inserts for
using our case to fire subsonic And still fire 650gr or 750 gr
at high speeds. Can't get 14.9 Russian cases, use ours in
same gun with inserts.




Break action I like, we did on a CBC by mono-blocking a 585
barrel, set up especially for Minie bullets of 440 to 540 gr.

You can see from above posts I like Enfields and here is picture
of how we set up action for long case and a singlestack magazine.
We open bottom of action for length and use a lip type magazine
insert to feed cases single stack. And lips are springy so we
can load from the top.



Here is the second gun I did years ago in the 585HE, an old style
Ruger 77. And at that time I used the cases I made myself and
they work great in the gun, high pressure loads, and extracted
easy like the new ones from Bertram.



Here is some math to show why I really like really big bores.
There is term called Average Barrel Pressure, which is the average of
all the pressures in a barrel, from the start where you have highest,
called peak pressure. to the lowest at the muzzle when bullet exits.
For high powered rifles average barrel pressure run 15-18000 psi.

There is a formula that can be used to get Average barrel pressure
fairly close if you know the muzzle energy.

We multiply ME times 12 and divide by barrel cross section x length.
We simplified it to get the 12 figure, It is inverse of the bore dia x 5
For the 585 it comes out about 10

Example a 458Win usually loaded to 5000 ft lbs, say in a 24" bbl.

ABP = ( 5000 ft lbs x 12) divided by (.17 sg in x 24") = 15,000 psi

Now you see there isn't a lot of room for big gains, as it would take
peak pressures damaging to brass and gun, to get say 50% increase.

Now example of 585HE in the 26" bbl we like, say a 7,000 ft lb load,
a real moderate load in this case. Could use 10 in place of 12,
but kept it all simple

ABP = (7000 ft lb x 12) divided by (.27 sg in x 26") = 12000 psi

The bigger bore allows for a much larger potential,
a 50% gain is easy to do.Ed

Here is a few of the variety of bullets we found or know about, we
can use in 585HE, about a third of them, from 440gr, to 750gr,
to 1200gr, to 1600gr.



Here is picture of what 200gr powder, in a case that had
the powder settled, looks like.



We now have more 585 new straight blanks giving a total of 9
basic blanks, with long ones for guys setting up target guns.
And a bunch more of the profiled barrels are being made now
to go with new ones we got left. One which went on this BBK
pictured, 3 on Enfields, one on FBW, one Ruger, 2 in PHs.
Guys have used 5 of the new slow twist barrels. Ed

There is a guy and his smith in AUS that has a reamer for the 585HE.
And maybe another firm there that can get a bunch reasonably priced
barrels imported in from the US. Our Mcgowen barrels are high quality,
hand lapped, and only half of what getting them in from other places cost.
Here is part of stuff that the guys have to work with..



Here is picture of the Mossy 390 action, after I'd set up for the 585HE.
Just to see how good the action is, and I have since set barrel back
and made it into a 24ga FH. Just makes an easy to work with test gun.
Being both use same size bore, and in 24ga with 3" chamber I can use
577 brass for 24ga cases, using same Minie and jacketed as 585HE.
58CAL IN ALL FORMS is where it is at, so to speak......Ed



PS-We have longer barrels now for target work including real heavy ones
of 1 5/8 inches, that some guys are working on getting bigger actions
set up to use them in. .
