<p>There is provided a lead-free small arms projectile (10) that deforms on impact with a target to rapidly dissipate the momentum of the projectile (10), minimizing penetration of the target. The projectile (10) has a jacket (28) that surrounds a first core (12) located in a rearward portion (30) of the jacket (28) and a second core (20) located in a forward portion (32) of the jacket (28). This second core (20) has a low yield strength and a tensile strength to yield strength ratio such that on impact, the first core (12) compressively deforms the second core (20), causing the seond core (20) to expand laterally outward from the target, increasing the surface area of the projectile (10) and dissipating the momentum imparted by the projectile (10).</p> |
