PMC has been providing high-quality ammunition in the United States for over 40 years, the Bronze line of ammunition continues the tradition. All PMC cartridges must pass through the rigorous inspection of an electronic powder check station. This station accurately measures the propellant charge in each round. If the propellant in any cartridge varies by a tiny amount – just two-tenths of one grain – the system stops and that cartridge is discarded. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.
