Plastics have long played a role in fire arms, seeing use in everything from stocks to handgun frames but now they're looking to get inside the barrel with polymer-based cartridge casings. Earlier this year PCP Ammunition (Winter Park, FL) launched a line of lightweight polymer-cased ammunition, creating rounds that reportedly offer comparable performance to brass cartridges with weight savings of more than 50% for the case and 25%-30% of loaded brass ammunition.
The creators also claim the new casings solve many of the issues that affected previous attempts at polymer-based cartridges through new patented designs and material selection. PCP says the cartridges can be loaded using standard loading equipment with a wide range of bullets for ground and air tactical units. There are currently five calibers available ranging all the way up to .50 cal.
