Patent

CA 2322411

The invention relates to ammunition suitable for firing from a side arm comprising a cartridge adapted to fire a projectile (6), the cartridge case (1) having at one end a portion (3) of reduced diameter, i.e. a bottleneck cartridge, the projectile (6) being held in the said portion (3) of reduced diameter (D), wherein the ratio of the external diameter (B) of the cartridge case (1) at its widest point to the external diameter of the projectile (6) at its widest point is such that when the projectile (6) is fired into a target, high velocity wounding is caused. The invention also relates to a gun barrel (10) through which the ammunition can be shot, and a gun comprising such a barrel. The projectile (6) has a diameter of 5.56 mm (0.224 inch). The length of the cartridge case (1) lies between 17 and 25 mm, its maximum diameter at about 9-12 mm. The cartridge case may be made from a 0.40 Smith and Wesson (S & W) cartridge case.

L'invention concerne des munitions adaptées au tir avec une arme courte comprenant une cartouche adaptée au tir de projectile (6), cartouche dont la douille (1) comporte à une extrémité une partie (3) à diamètre réduit, c'est-à-dire une cartouche à épaulement, le projectile (6) étant maintenu dans cette partie (3) à diamètre réduit (D). Le rapport du diamètre externe (B) de la douille (1) au niveau de son point le plus large, au diamètre externe du projectile (6), au niveau de son point le plus large, est tel que le projectile (6) tiré dans une cible présente un pouvoir vulnérant de projectile à grande vitesse. L'invention concerne également un canon d'arme (10) à travers lequel on peut tirer les munitions et une arme comprenant un tel canon. Le projectile (6) a un diamètre de 5,56 mm. La longueur de la douille (1) est comprise entre 17 et 25 mm et son diamètre maximum entre 9 et 12 mm. On peut fabriquer la douille à partir d'une douille 0.40 Smith et Wesson (S & W).
