<p>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.</p> |
