Abstract

A subsonic cartridge (10) that enables a conventional automatic or semiautomatic weapon (36) to fire a projectile (30) at a subsonic velocity and cycle the weapon (36) to eject the spent cartridge case (12), without the sonic report characteristic of supersonic projectile (30) velocities. The cartridge (10) includes a case (12) having a tubular shape with an open end (16), an oppositely disposed head (18), and a bore (14) therebetween. The head (18) of the case (12) includes a primer cavity (22), a web (24) separating the primer cavity (22) from the bore (14), and a flash hole (26) through the web (24). A primer (28) is stored within the primer cavity (22), and a projectile (30) is disposed within the bore (14) so as to close the open end (16) of the cartridge case (12). A charge cavity (34) is delimited within the bore (14) between the web (24) and the projectile (30). The charge cavity (34) is sized and shaped to contain a limited amount of propellant charge (32) that propels the projectile (30) from the cartridge case (12) at a subsonic speed.
