Target/ELR 375 HE..

[hubel458]

About 416 cal bullets............The heaviest 550 gr for Extreme ELR probably be best 8 to 1 twist , in 416 caliber bullets,
and 500 gr 9 to 1, and 470gr 10 to one, Barrels I have 10 to 1.
Now a novel idea is to lighten rear of bullet with small shallow hole drilled in base, might do better long range.which would allow 10 to one barrel stabilize the heavier bullets for ELR.
Have hole maybe 2/3 size of tail end of boat tail...Some going to have to try it to see if it is accurate. Ed.

About 416 cal bullets............

The heaviest 550 gr for Extreme ELR probably be best 8 to 1 twist , in 416 caliber bullet,
and 520 gr 9.5 to 1, and 470gr 10 to one, Some barrels I picked up are 10 to 1.......

Now a novel idea is to lighten rear of bullet with small shallow hole drilled in base, might do better
long range.which would allow 10 to one barrel stabilize the heavier 550 gr bullets for ELR.
Making bullet nose heavier makes it more stable in flight, needing less spin,
like our hollow base 585 cal minie bullets only need 48 to 1 twist, or less
while out regular 585 bullets need about 24 to 1 to stabilise them..............

The winner of the King Of 2 Mile shoot last week was using 416 Barrett with a 1 to 10
twist, with a 500 gr CEB Lazer bullet, ...Robert Brantley, with Manners Stocks....

Paul Philips was third with a 416...

GOOD NEWS-- There is now an importer and seller of our 585 HE brass getting set up here,
in US, hopefully will be in stock, few weeks........ http://bertrambrass.com .. .. Caleb Hallet..

Have got another intermediate size action besides the Montana PH our guys working on,
to do speed testingwith. It is big long REM style action that can take our 416 HSM, ED

 

[hubel458]

Experimental intermediate size action with the Montana PH, for comparison.

It is an experimental action for our 416 HSM, to do our speed testing with

and get a better action than Cheytac size actions, for bigger case ELR use,

without going all way up to more expensive, huge actions.

It is big long round style action that can take our 416 HSM, almost

1.6" diameter and .800" bolt, with locking lugs nearly as big as most

BMG actions.... ED

 

[hubel458]

Here is picture of the bolt from the experimental action,

with our 416 HSM case in it. Note the amount of the

base size of locking lugs, the amount of area on the bolt...ED

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..

Here are various sizes........


16ga-- .810" rim,

20ga-- .760" rim,

24ga .725" rim,

28ga .680" rim....

 

[hubel458]

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..
