4. Polymer-Cased Telescoped Ammunition
Using high-strength polymers rather than conventional brass cases, polymer-cased telescoped ammunition marks a major development in ammunition design. The telescoped form reduces total length by up to 30% by embedding the projectile totally within the casing. More small weapon designs and better feeding dependability are made possible by this combination. Although structural integrity under harsh conditions is maintained, the polymer construction lowers weight by up to 40% relative to brass-cased ammunition. Furthermore enhanced by recent advancements are the storage stability and temperature resistance of the ammo.
