polymer-cased ammunition

Polymer-cased ammunition uses a plastic or polymer material instead of traditional brass or steel for the cartridge case. This design reduces weight, allowing soldiers or shooters to carry more rounds and making handling easier. The polymer casing functions similarly to metal cases, containing the gunpowder and primer, and chambering in firearms. Advances in materials technology ensure reliable performance, seal integrity, and durability comparable to metal cases. Overall, polymer-cased ammunition offers lighter weight and potential cost savings while maintaining the necessary performance standards for military and civilian shooting applications.
