Non-expanding, deep-penetrating bullet has a lead core enclosed by a strong metal jacket. It provides smooth, reliable feeding in all types of semiautomatic handguns. All PMC cartridges must pass through rigorous inspection at an electronic powder check station. This station accurately measures the propellant charge in each round. If the propellant in any cartridge varies by just two tenths of one grain, the system stops and that cartridge is discarded. No other ammunition manufacturer can truthfully assure you greater uniformity and reliability. Per 50.
