A projectile designed to be fired from firearms. The projectile has a generally conically shaped jacket having a forward tip, rear base, a body portion, and a central axis. The jacket is formed of a first metal. Located inside the jacket is a generally conically shaped penetrant which is formed of a second metal. The penetrant is formed with a forward tip, a rear base, a body portion, and a central axis. The tip of the penetrant is positioned substantially adjacent the tip of the jacket with their longitudinal axis being aligned. Finally, a core, which is formed of a third metal, fills the jacket and is located about the tip, body, and base of the penetrant. The third metal has a hardness less than that of the first and second metals while the second metal has a hardness greater than that of the first metal. This arrangement causes the projectile to disintegrate upon striking a target with the penetrant breaking through the jacket and the core causing them to expand and decelerate while the penetrant retains its shape and continues to pass through the target. The rear portion of the jacket body includes a shoulder defining an enlarged radial portion which extends along said body to the base. This enlarged radial portion comprises that area of the casing engaged by barrel rifling when the projectile passes through the barrel. The shoulder is located to generally be aligned with the base of the penetrant.
