1. A petalling projectile, comprising:
- a front end;
a rear end;
a central longitudinal axis;
a core centered on the longitudinal axis;
means for allowing petalling of the core away from the axis during the core'"'"'s penetration into a target, the allowing means including means for retarding petalling at initial impact of the projectile with the target;
the allowing means further including acceleration means for enhancing subsequent petalling of the core after initial target penetration by the projectile, the acceleration means including a stem extending along the axis from the front end to the rear end, the stem fixed to the core before the initial impace and axially loosening from the core after the initial target penetration, the acceleration means further including a radially inwardly deforming wall at the rear end, said stem and said rear wall formed as a single one-piece element of the same material throughout, said stem having a smooth outer surface over substantially its entire length, said stem and said rear wall being of a harder material than said core.

Abstract
The invention is an improved partially jacketed projectile intended for small arms use. The projectile includes a central stem integral with a rear wall of the projectile, the rear wall in turn being integral with the partial jacket. A core surrounding the stem and encased by the jacket is softer than the material forming the stem, rear wall and jacket. The jacket retards core petalling during initial projectile impact whereas the rear wall configuration enhances petalling when the projectile achieves subsequent target penetration.
