    Our 585 HE could be called a 15, It is close,

    most time you make the cases fit available bullets

    and specific uses that some diameters have

    an advantage for, in guns of a certain weight...ED

    That looks like too much fun for my shoulder, though it's nice to see the anti-tank rifle making a comeback

    They are neat old gun to have fun with..

    Guys are still having trouble with various cases with too thick of sides. The thick sided case have enough brass material to thin up sides and stretch them way out to 4 or
    more inches,,And they'd work with proper slow powders, we are working on a 458 HSM experiment, with case holding 400 gr ball powder under the bullet. ED

    I guess economy isn't an option with a case using 400 grs. of powder.

    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.

    There are some getting cases built thick and having extraction

    problems at high pressures, using regular speed powders. Don't work..


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

    The thicker brass doesn't springback as much?
    Makes sense I guess, just never would have thought of it as a problem.
