585 HE -- Cases In Production --

[hubel458]

.....


It is possible rig up holders for many types setups.,

About shellholder supply for big cases,

RCBS and others make slip in holders for shotgun cases

that can work or reworked for big rimmed rifle cases...

Here are various sizes.......

16ga-- .810" rim,........ 20ga-- .760" rim,....

24ga-- .725" rim,....... 28ga .680" rim....

Ch4d and Buffalo Arms also have these larger shellholders...


We fireform the 416 HSM with 65 gr of medium speed

surplus powder, with rest of case filled with farina

and grits mix, with a play dough plug in the neck.

It is loud, so we shoot it into big container through a barrel size

size hole, so the sound is muffled, so it doesn't deafen us..


It is great getting more companies making 416 caliber bullets,

long target and bore rider bullets. Ed..

Wonder if a PTRD with 5 ft long barrel is stable enough

for ELR , rebarrel to 416 and use our 416 HSM, 500 gr bullet ....

.Here is up north guy using 585 HE in a PTRD with inserts,

Light load.....Inserts are in the shape of the 14.5mm case....

20mm Vulcan is a big case that works ok, without having

the sides made too thick...They have thinner sides

than smaller cases guys are getting that have the sides

made too thick and won't extract easy or work with high pressures.


Here Barnard P Cheytac bolt that would do for our 416 HSM..Ed......

Got guys doing various 416 HEs..

One just built a 416 HE, just been testing it a few days..

And using 168gr of HBMG 475 gr CEB, tested it, in good

conditions, 2 shots at 1800 yards and was within

a 1/4 of minute accuracy...A few shots at shorter ranges

had same accuracy. Ed..

The fellow that set up our 416 HE in an ELR rifle

And have got 460 HSM specs setup, the impetus for that is some
asking about one and new great line of 458 bullets CEB now has.

It will hold more powder than the 416 HSM and will get
a 572 gr as fast as 416 HSM gets a 475gr.....Ed..

You got a sponsor for powder?

[hubel458]

We already have the real slow powders we need, most of

them needed are the real slow military surplus ones.We have good supply.

Double base ball and extruded; and single base extruded... ED

The guys that did the super accurate 416 HE did another
416 HE that has an 8" longer 42 inch K&P barrel..

Used a Stiller action and same load with 475 gr bullet, as in
first gun and and gained about 200 fps with good accuracy.
3065 fps. Tested 2 groups of 3 and less than 1/2 min moa.

And loads they used are not the highest speed loads
the cartridge is capable of....Here is print with specs for
the 416 HE reamer chamber ....Ed....
