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.

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
