    Here is sectioned 585 HE case in the middle, we first made from

    another case, years ago before we had factory run of brass and

    it had perfect thickness on the sides and inside corrner.

    We could fire them many times without sides thinning..

    First case is factory run of our 585 HE, 3rd is case that is too thick

    of sides and sticks at high pressures..


    Here is pic of our factory run cases necked down to 375 and fired 4 times

    at high pressure on the right, with unfired case on the left. Our case is not

    perfect but does work...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
