Mushroom cartridge for hand held firearm - has soft material caseless nose with blind hole in tip housing metal ball

摘要

The cartridge for a hand-held firearm has an outer brass case (18) at the rear, holding the explosive charge (19), and an inner cup-shaped section (13) at the front, holding a caseless portion (11) of soft material, formed into a rounded nose, with a blind hole (35) inside its tip housing a metal ball (14). On impact, the soft material is formed into a mushroom shape, and the ball is released. Alternative designs have the blind hole deeper or shallower, and tapered or restricted at the outlet. These are combined with other variations such as channels (15) around the soft nose, or double holes to hold more than one ball, one behind the other, also gas discharge holes. These special features may be used in combination.
