Re: 585 HE -- Barrels of Cases --

I used tang action77 magnum and a MkII mag action.
Rim .654".. The RSM is best.
Savage will work have figure out a different kind of extractor.
Savage has more room like the Enfields and MRC PH.

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.

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

Awesome thread Hubel ! I always amazed at your ingenuity .
I do think the 585 HE with a 650-700 gr soft nose or mono metal expanding bullet at 2100+ fps would be ideal for those 20' or closer fights with a big and mean brown bear in extremely dense brush like we have in Southeast Alaska. . Could that velocity be got from a 20" barrel?
In an 11 lb rifle how is the recoil compared to a 500 A-Square ??

Also. Have you seen the new Richardson+Roberts action? . Matt Roberts is a friend of mine and wants me to have him build me a rifle on one of their actions. I think the largest size they make would fit the 585 HE nicely.

2100 with a 650gr easy to get from short barrel, you can get

2700 if you want with 650 gr in short barrel.

at 2100 recoil in 11lb gun be moderate.

I haven't seen that action, can you post info and pictures about his large action.


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

Re: 585 HE -- Barrels of Cases --

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

Also now lower Michigan shotgun only area is being allowed to
use short pistol cases in rifles, like Indiana, so if folks want big power with rifled
barrel, good accuracy, go a 24ga FH with rifled barrel , long brass cases.
Why lose power, just do a hairy 24ga... With good brass cases..Ed
