What’s so Special about the 300 PRC? With several .30 caliber cartridges already firmly set in the minds of rifle shooters, the venerable 300 Winchester Magnum is one example, why develop a new cartridge? At the request of the US Military, specifically the U.S. Special Operations Command (SOCOM), the ammunition industry was asked to develop a cartridge that would give snipers a 50% hit probability at 2,000 yards. The .300 PRC was developed by Hornady as the solution to meet this stringent requirement.
Achieving optimal aerodynamic performance. To accomplish the goal, Hornady developed the 300 PRC to “take advantage of long, heavy for caliber bullets that are capable of delivering the highest levels of accuracy and aerodynamic performance.” Currently, Hornady has 225 gr. Match and 212 gr. Hunter loads available, both using proven ELD technology. Common, magnum speed rifle powders are used and result in extremely consistent velocities and increased barrel life compared to most currently available magnum cartridges.
