The 6.5 PRC from Hornady might seem like a new cartridge, but it has been a long time in the making—since 2013, in fact. The driving force behind its development was George Gardner, owner of GA Precision, who was looking to create a hard-hitting long-range round for both hunters and competitive shooters, particularly those in the Precision Rifle Series.
According to PRS rules, cartridges cannot have muzzle velocities in excess of 3,200 fps. In addition to that restriction, Gardner also wanted to run the cartridge through short-action receivers. These two parameters are why he decided on a 6.5 mm/.264-caliber round.
