Projectile for hand and shoulder weapons and a cartridge fitted with said projectile
First Claim
1. A cartridge comprising a non-deformable projectile for hand and shoulder weapons having a body and a nose, said nose having a base adjacent to said body and a free end, said body being fitted into a cartridge case filled with charge powder, the longitudinal cross-section of the said nose being defined by two lines which are concave when seen from the exterior and symmetrical with respect to the axis of the projectile, the tangent to each said concave line forming with the axis of the projectile an angle which is larger near the base of the projectile nose than at the free end of said nose, the value of said angle being equal at a maximium to 90°
- at the base, said body being cylindrical and being provided with an axial cavity, said cavity being open at the end remote from the projectile nose and filled at least to a partial extent with the charge powder in said cartridge case, the volume of said cavity and of said cartridge case and the mass of charge powder contained in said volumes being such that said projectile has an initial velocity which is substantially two to three times higher than that of a conventional projectile having the same caliber and fitted in the same cartridge case.

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.
