Trailboss and super light bullet, be big fun.

Here is a few of the variety of bullets we found or know about
to 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. .

Here is a picture of the first 585HE to be done and firing,
in Australia, owned by the poster, tankhunter on AR forums.
Fellows there can get cases from Bertram. I can send
dies and reamers.And can get dies from CH4D.
There soon will be 3 reamers there.
And now a company starting to make 585 barrels there.
I have about 17 here, so no waiting here.
Allan and Grant Swan. in Redbank, Queensland...
allanswan at uplink.net.au.

WE have cases with plain heads if guys need some for
wlldcatting, necking down, and they can put on their
own headstamp.Ed

We've put some of the 585HE bolt guns in composite and Hogue
stocks, and they are rugged for extreme weather. And they
don't break under heavy loads. Prices are nice and they have
aluminum pillars and/or aluminum bedding blocks.
And with their hollow butts very easy to add weight to take up
recoil. If lead and epoxy added to a complete fill of the hollow,
too much weight, so I found a nice cheap substitute.
We now using rubber coated mouse balls that we have bunch of.
They are steel with rubber coating, and the right weight.
They add just the right weight and and wedge in good.
And won't rattle with coating, and we hold them in tight with
a piece of dense foam under butt pad.

We get asked about how much speed potential we have. And
we start by mentioning cases can hold 190-200 gr of ball powder
with the bullets loaded out longer. And we have those heavy
powder loads with 650 gr jacketed bullets, in the Enfield
pictured I use as one of my test guns.

And more fun shooting, using a pistol grip on one of the
585HE falling block test guns. Real heavy loads try to spin us
around like a weathervane.. Ed

A related case to our 585 is the 24ga FH that has 3" chamber and
brass cases reworked 577NE cases, that we reduce the rim down
to .720"... the 24ga size rim...We make minimum chamber so that 24ga
plastic cases, 2.5" long just fit. And min chamber cuts down on a lot
of brass case expansion, which the wears cases out.
The barrels are same bore barrels as our 585 and the hollowbase minie
bullets work great in it, the ones that are .585", 440gr to 540gr.
Makes hairy 24ga gun for deer, etc. Be useful in shotgun only areas.
Guys on GB sells the .585" minies. And the brass cases, we don't have
to wait for them to be made.

Here is what 585HE barrel and its monoblock look like before
screwing the barrel in.This one was 585HE, but process same if
monoblocking in 24ga FH...Ed

Here is picture of 585HE with 24ga FH ...585 the longer one.
Both use same bullets/slugs, same caliber rifled barrels.
Different easy usages, 24ga FH is an easy setup in break
actions and 585HE in bolt actions and falling blocks.

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
someone pulled out, and they wouldn't stay in tight after pulled.
Supposed to be for 20ga, But this sabot was a real loose fit
in 20ga, though made for 20ga, so I shrunk diameter of bottom rib,
fits perfect, super tight, in 24ga and 585HE brass cases. A press
in tight fit gives good resistance for good ignition. real tight fit.

Here is a 24ga/585 discarding sabot that holds .452" 45cal pistol
bullets. Made by Hornady for 58cal Muzzle loaders..
With 250 gr bullet in 585HE, hopped up load will go about mach 4.

For ease of getting actions in stocks, I like composites.They are
strong. come colors, many can be painted with tough finish paints.
Usually need weight added for big bore use. But not too miuch..
An 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

 
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 100 cases loaded with CEB solid nose bullets
and hollowpoints. This bullet is a turned solid with wide meplat
or wide hollowpoint. .

Here is pic of a Enfield with a jeweled and polished bolt, going
to be 585HE. In the back, Bolt jeweling and polishing done by the
great craftsmen, Bob Snapp, years ago.

Picture comparing unfired and fired cases showing our tough cases
One on the left fired with 650gr at 2400 and base above belt
didn't hardly expand, Sized the top and reloaded/shot again.
And AHC will make guns now with our 585HE for any wanting
super top quality guns.They have some cases to give to guys
as a sample to show guys the case. Ed

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

Here is a different look at 585 sabots holding 458cal bullets.
Sabots hold leafd as well as jacketed.

Here is a long turned streamlined bullet in our 585.

 
Anyone wanting to import barrels, actions, cases, etc into Canada from
here can work through Prophet River Firearms in Lloydminster, AB.
The here being the US, as well as our group with barrels, dies, cases,
and McGowen with .585 barrels in stock, CH4D with 585HE dies
in stock, gunshops with # 31 shellholders.
And later few retail outlets setup with cases in stock... . Ed

Hubel458... I have been following your work for a few years on a gun forum I used to be a super mod on, and I am still impressed. Nice to see it's all coming through for you; wish I could afford to shoot something like that often. Boss lady would kill me!

Another application for our 585 HE is for guys with the 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 in a PTRD with almost a 5 foot long barrel can get 650gr
spitzer bullet to the same speed the 14.5mm gets a 900 gr using
3 times as much powder. 3300 fps. Or get a 900gr at 2800.
Great possibilities for fun shooting. And tactical use in a place
where it would be useful to reload in the operations field, where
steel cases are scarce. A 100 cases do over 2000 reloads.

I like Enfields to put our 585HEs in, for reasonable cost guns. .
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, one on the right . Something even a novice
like me can do.....

A lot of guys are crazy about CEB bullets. Here are light 450gr
ones in our 24ga FH. The hollowpoint can range in weight 450gr
to 700gr.. The 24ga FH is nice complement to our
585HE for the shotgun only deer hunters... 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. That sabot is one made for ML, but
with .452" bullet in it is a real tight fit in brass cases, to stay
in place and give good ignition. A 250 gr bullet would go about
mach 4 with a top load..



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" ..The 5th, 6th,
7th blanks on bottom are straight 1.375" 585 regular twist blanks.
One in paper wrapper is slow twist 585 barrel...Ed

Have you had an actual pressure test done on your heavy loads, or any other loads for that matter?

Since you are working with CH4D, and they are located here in Ohio, USA, did you see about getting this round approved by the ODNR for whitetail deer in Ohio? As of now, the biggest rifle cartridges allowed (must be straight walled cases) are the .50-110 and the .500 S&W. We can use slugs up to 10 ga. and muzzleloaders up to 10 ga., which are basically 775 caliber.

Our friend Brian from the far north went to Africa with his 24ga FH he did in
a NEF break action and got 3 nice buffs with it. Good job.


Our 585HE, 700HE and the great 12ga FH are now in the new COTW book
published in Oct, now out for sale,




We now have our target 375 HE cartridge, made by necking down our 585 HE.
The other couldn't make enough 375s, so we started our own. It has different
shoulder taper, length, neck length, improved over the other one...Got a bunch
guys doing it, most into the 2 mile shooting venues, We're making cases,
testing, reamer prints at reamer guys, we are getting guys going. King of 2 mile
shoot last year really got the interest booming for 375 necked from our case,

Here's how we size and seat 375 HE, a simple die, a 1" die, no huge dies needed
A die we can make with resize reamer from reamer guy, a regular die body,then
pass on to the next guy, one reamer can make whole bunch of dies for folks.

I do primer work separate, not in the press.That way I can clean pocket, check
flash hole,....... SO First with lock ring set, I size cases.

When coming back out of dies with case, we notice the case still well centered,
held straight, when it is down as far as the length of the 375 HE neck... IE
the sides and shoulder corner still supported tight. About .35" down.

So we put washer or another lock ring on, same thickness as neck length,
below original lock ring, screw down tight tight in press,

Dies had a 5/8 x 24 thread in top, had powder fill bushing and other stuff same thread,
reamed out from bottom to set bullet height, with ram, case,and bullet up,

After priming, loading in the powder charge, we carefully start(boat tail makes it easy)
bullet in case by hand, slide up in die, into holder, raise ram to to top, bullet seated
perfect. Die can have different thread in top as long as big enough to hold seating
bushing of some kind , that can be made from many items.

These target bullets held in by strong neck tension, no crimping needed, and notice
bullet point will get no marks or dents, fast, easy, no 380-500 buck special dies.
Bushing centering bullet on ogive is very accurate.

OVER 900 375HE cases piled behind presses getting done. About 600 on another
bench nearly ready. Small batches in shelves.And we will do more.

All 375 info, prints, specs, pictures, load data, etc, is public domain, worldwide,
for any target, hunting, etc, use..Ed

Here is picture of one of 3 buffs our guy from Canada got in

Africa with our 24ga FH he did on a NEF, in 2nd picture








Here is the neck die setup, with insert stems/plugs for the top that

are set in .020" steps to make our 375 HEs shown behind

from our 585HE cases. 900 cases behind and 600 on

another bench, mostly done, and 600 started elsewhere,

We also made a hydraulic form die, 375 HE test gun, starting with

lighter bullets, for example got 340 gr to 3700,

Will test up to 400gr We will find top speeds and powders needed

to get that, and have info where to get powders. Reamer prints are

at reamer guys, all prints and info is public domain... Ed

Could you please tell me a little more about that Greener rifle you had a photo of? My first reaction when I saw it was that you were doing something with a Martini-Henry action, but I could not find the lever to work the action. Looks intriguing.
