The 6mm Creedmoor is the little brother to the very popular 6.5 Creedmoor. It has similar ballistics to the .243 Winchester, but its shorter length allows long, heavy bullets to be seated in the magazine. This caliber is an excellent choice for hunting, but its popularity was gained as a competition cartridge. Some of the new competitions, such as the Precision Rifle Series, require a lot of shooting and this cartridge is light recoiling making spotting hits and misses easier for the shooter. This brass features a Small Primer pocket and small flashhole for use with Small Rifle Primers allowing loaders to squeeze more velocity and pressure out of the cartridge without primer pockets Mfg: Starline
