Abstract
A telescoped ammunition round including a plastic case having a cylindrical casing, a front end cap and a rear end cap, the front and rear end caps being fitted at front and rear ends of the casing. The round further includes a projectile, a propulsive charge and an ignition device disposed within the casing. Sealing means are provided to form a gas-tight seal between the front and rear end caps and the cylindrical casing to prevent escape of propellant gases generated from the propulsive charge. Importantly, axial retaining devices are included to prevent longitudinal movement of the front and rear end caps before firing, and allow movement thereof after firing, wherein the end caps are not completely separated from the casing after ignition of the propellant charge.
