    Here is picture of thick 375 case sent to me, with thick sided trex case, and our HE case,
    The thick 375 case is .050" bigger OD base, but inside is no bigger than HE cases..
    These thick sided 375s stuck for the guy using them, when loaded over 44,000 psi....

    Got guys asking and doing it, to do 416 HSM case for BMG actions, so leaving rim same,
    as the original bmg rim, so will neck them, fire form to the longer shoulder, like the others.
    Base a little bigger, Shoulder same diameter, same 30 degree slant, neck will be same..

    Inside of case still has close to same shape, volumne within 3 % as ones we slimmed down more.
    Some want to use bmg actions and can't wait for intermediate actions, or already have bmg action.
    And they are really getting interested in the complete line of 416 CEB bullets now being done
    clear up to 550 gr...

    So there will be 3 versions, one for actions .750" bolt, one for .800-.850" bolt,
    And one for bigger bmg bolts. The ones for BMG called 416 HSM2 ..

    Here is 416 HSM guy working in a Montana PH, in a heavy thumbhole target stock. Ed

    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..

    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

    What may have started out as wildcatting for shotguns has evolved into wildcatting for rifles that kill at both ends.

    I personally was wildcatting for big bore rifles for
    many years before getting into 12ga FH, many years
    before the internet.. 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 action and .800" bolt, with locking lugs nearly as big as most

    BMG actions.... ED

    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..

    Here is link to guy doing special 585 HE in the EU,

    Good pictures............www.585he.cz

    We tested intermediate action with a 700HE barrel we had here.

    Just temporary to test strength. 1000 gr over 3100..

    Action worked fine.. Ed.

    In 416 HSM got a 415 gr long target bullet 3800,

    with plain barrel, no brake, on intermediate action,

    Our 416 HE gets same 415gr bullet to 3300.Ed
