PMC's Bronze Handgun is manufactured with the same quality and dependability built into their premium grade Starfire ammunition. All PMC cartridges must pass the rigorous inspection of the electronic powder check station. If the propellant in any cartridge varies by as little as two-tenths of one grain, the system stops, and that cartridge is discarded. Ammunition is brass cased, boxer primed, fully reloadable, and 100% clean burning and non-corrosive. These valued characteristics run throughout their entire line. Battle Packs are used as a secondary form of waterproofing for your ammunition. This is great for storing or caching your ammunition for future emergencies or time at the range. Stack these in your basement or bury them at your cabin. Either way, the Battle Pack has you covered.
