416 HSM, 416 HE, 375 HE, 585 HE...............

Our 416 and 375 HEs are made from our 585 brass,
And 416 HSM are made from BMG brass...

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

The heaviest 550 gr for Extreme ELR probably be best 8 to 1 twist , in 416 caliber bullet,
and 500 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, he is with 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,
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 testing with. It is big long REM style action that can take our 416 HSM, ED

I've had no trouble shooting 450 gr. bullets in a 1-13" in a 416 Barrett custom and having them be stable, as per CEB's recommendations for twist rate listed on their website.

That Lazer nose being lighter and thus making

the bullet being longer overall compared to

equal weight regular bullet, the guys say

makes for better longer range accuracy. Ed

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

Ed, I think your products are good, but most of your time has been sent on other forums slamming Trump. I know that you are a democrat,but some of your post are way far left. I think you are probably a good guy, just misguided.
