    The information from the crane website does not specify. I would venture a guess that it is the GM215M Magnum since Federal has the contract. You might try the GM215M mag primer and the GM210M LR primer and see which gives a lower extreme spread. If the 210m does you might have to increase powder to attain the same velocity.

    220 MK
    H1000 @ 77.7
    FC military brass


    very hot round........better at 77.0 with CCI BR-2 primer

    The military doesn't care if the brass is reloadable, only the performance.

    Yes the MK 248 Mod 1 I heard production was put on hold due to excessive pressures.
    Same problem they had with MK 118 LR and RL 15.

    I run 77.1 of h1000 which is hot enough for me
