<p>A frangible projectile comprising a core (96) formed from one or more metal powders incorporated into a metal jacket (10). The metal jacket is initially cup-shaped with an open end (14) and a closed end (16). The surface (20) of the closed end (16) of the jacket which faces inwardly of the volume of the jacket is indented and stressed over substantially its entire area in accordance with a pattern of indentions (22) which enhances the frangibility of this closed end of the projectile when the projectile strikes a target. Upon the projectile of the present invention striking a relatively hard target, the initially closed end of the jacket, which now has been indented and stressed, disintegrates into minute particulates, each of which loses its momentum rapidly such that these particulates fall harmless away from the target.</p> |
