Firearms and ammunition

A combination of a self-loading sidearms gun barrel and ammunition, said gun barrel having a chamber at one end so shaped and dimensioned as to receive said self-loading sidearms ammunition comprising a cartridge and a projectile, said projectile having a limit velocity that is not less than 518 meters/second, the cartridge case having a substantially cylindrical first portion of a first diameter, a substantially cylindrical second portion of reduced diameter, and a conical portion intermediate the first portion and the second portion, the projectile being held in said portion of reduced diameter, and the cartridge being adapted to fire the projectile, wherein the length of the cartridge case is less than or equal to 26 millimeters, wherein the ratio of the external diameter of the cartridge case at its widest point to the external diameter of the projectile at its widest point is such that, when the ammunition is fired through the barrel, high velocity wounding is caused when the projectile hits a target at at least the limit velocity, wherein the ratio of the external diameter of the cartridge at its widest point to the diameter of the external diameter of the projectile at its widest point is greater than or equal to 1.4 to 1, wherein said projectile is jacketed, and wherein one end of said chamber enters into a rifled barrel of a diameter corresponding to the diameter of the projectile.

Self-loading sidearms ammunition comprising a cartridge case and a projectile, said projectile having a limit velocity that is not less than 518 meters/second, the projectile having a substantially cylindrical back end, an opposing substantially pointed tip end, and a circumferentially extending jacket wall extending between the back end and the tip end of the projectile, the projectile further having a longitudinal axis, wherein a portion of the jacket wall proximate the tip end of the projectile curves inwardly toward the longitudinal axis of the projectile to form the substantially pointed tip end of the projectile, the cartridge case having a first portion of a first diameter, a second portion of reduced diameter, and a conical portion intermediate the first portion and the second portion, a portion of the projectile proximate the back end of the projectile being held in said portion of reduced diameter, and the cartridge being adapted to fire the projectile, wherein the length of the cartridge case is less than or equal to 26 millimeters, wherein the ratio of the external diameter of the cartridge case at its widest point to the external diameter of the projectile at its widest point is such that, when the ammunition is fired in a weapon having a barrel, the projectile exits the barrel at a muzzle velocity sufficient to strike a remote target at not less than 518 meters/second, and wherein the ratio of the external diameter of the cartridge at its widest point to the diameter of the external diameter of the projectile at its widest point is greater than or equal to 1.4 to 1.
