What Primer in MK 248 Mod 1

What Primer do they use in the MK 248 Mod 1 ammo ?

Fed 215 Match are Fed 210 Match?gun)

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.

In the Specs page I found they stated Large Rifle Primer Nickle........I guess Fed 210 Match .......

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
