ABSTRACT:
A small caliber non-toxic penetrator projectile has a first core and a second core tandemly aligned and enveloped by a jacket. The first core has a hardness greater than the hardness of the second core that has a Brinell hardness of between about 20 and about 50. The hardness of the second core is significantly higher than the hardness of lead and when the first core strikes a target, the second core resists compressive bulging. As a result, more kinetic energy is transferred to the first core rather than diffused along the surfaces of an armored target. The more efficient transfer of kinetic enables the use of lower density second cores, such as annealed copper.
