  • Projectile for hand and shoulder weapons and a cartridge fitted with said projectile
    Patent number: 4572077
    Abstract: A projectile for hand and shoulder weapons has a cylindrical body and a nose, the longitudinal cross-section of the nose being defined by two concave lines which are symmetrical with respect to the axis of the projectile. An internal cavity formed within the projectile body and open at the end remote from the nose is at least partly filled with charge power which has been introduced into the cartridge case. The initial velocity thus imparted to the projectile is higher than that of a projectile of the conventional type and of the same caliber.
