MK 248 MOD 1 .300 Winchester Magnum Round

I stand corrected the correct primer was Fed 210 Match and they do not crimp the primers.

I suggest the Berger 230 OTC load ........I changed from the 220 MK to 230 OTC.

Very Happy

Yes they did halt production of the MK 248 mod 1............way too hot, hard on throat and even after firing could not reload the brass due to primer pockets to loose.
