<p>A bullet (10) comprised of a jacket (11) of malleable metal having a closed nose portion (13) and a rear end portion defined by a cylindrical wall, the closed nose portion having wall-weakening areas (22) encapsulating a forward core (21) made of a deformable material which promptly deforms, collapses axially, and expands radially to a substantial extent along with the weakened wall area, when the bullet strikes a target. These weakened wall (22) area are in the form of longitudinally extending, deep, internal or external, circumferentially spaced grooves with underlying web areas which are ruptured by the core material. This core is preferably made of rubber, urethane, silicone, or one of a substantial number of plastics, each of which has a hardness within a range of Shore A 20 to Rockwell 122. A second core (23), made primarily of metal or plastic, and preferably softer than the metal of the jacket, is seated, under pressure, behind the nose and within the rear end portion of the jacket.</p> |
