ABSTRACT:
Improved small arms ammunition comprising a conventional primed cartridge case and a hollow projectile in tubular geometric form is provided according to the present invention. In accordance with the teachings of this invention, the hollow projectile in tubular geometric form is characterized by a nose of circular cross-section expanding back to the main body of the projectile. The main body of the projectile includes a rotational band about at least a portion of the periphery thereof and is backed by a pusher disc and obturator to seal off the central core of the projectile so that propulsive force may be imparted thereto. The tubular projectile is lighter than its comparable conventional counterparts, exhibits gyroscopic stability and is capable of being fired at higher muzzle velocities and producing less recoil than that associated with conventional small arms ammunition while at the same time depositing a great amount of kinetic energy upon impacting the target.
