ABSTRACT:
The invention is a firearms projectile having an improved petalling action upon impacting a target. The projectile includes a slug whose head is separated into petalling elements by fins of a softer material than that of the slug, the head defining a central recess from which the fins radiate. The slug has a core therein which is forwardly and rearwardly tapered and is configured to assist the outward movement of the petalling elements after the projectile impacts. The cylindrical walls of the projectile provide a limited, controlled degree of longitudinal support to the petalling elements and the projectile includes means to force the cylindrical walls outward and away from the petalling elements once impact begins.
