Just a friendly heads up. US Coast Guard uses .40 S&W ammunition, specifically MK 309 MOD 0 155gr ball and MK 308 MOD 0 155gr JHP. Both loads have crimped primers, believe it or not the USCG is part of the Department of the Navy, ie military. Even though they have power of arrest, LE function, they are still part of the military, thus getting crimped primers. We've got a USCG base here locally and have been seeing the .40 S&W crimped brass on the range they shoot at. Contract has been awarded to Federal Cartridge. Keep your eyes open when sorting brass and be on the lookout for crimped .40 S&W brass now. Should be only Federal headstamps.
