Introduced to the shooting world in 2018 by Hornady, the PRC in .300 PRC stands for "Precision Rifle Cartridge". This new cartridge features a .532" head diameter, a 30-degree shoulder and unlike previous generations of magnum rifle cartridges, has no belt. Coupled with long, heavy for caliber VLD target or hunting bullets and relatively fast twist rate barrels, the .300 PRC ushers in a new era of .30 caliber performance. Mfg: Peterson Cartridge
