  • Patent number: 9797696
    Abstract: Various embodiments of projectiles are described. In one embodiment, a projectile includes a projectile core having a central recess formed therein, the central recess including a conical recess portion and a cylindrical recess portion. According to certain aspects, the projectile core may include a core base, and the central recess of the projectile core may extend from a leading circumferential rim of the projectile core to the core base along an axis of symmetry of the projectile core. The projectile core may further include projectile fingers each separated by a kerf, extending longitudinally from the core base to the leading circumferential rim, and extending radially apart from the axis of symmetry between an outer periphery of the central recess to an outer periphery surface of the core, and a nylon tip including a spherical nose, a conical taper portion, and a cylindrical anchor pin.

  • Publication number: 20160047638
    Abstract: Various embodiments of projectiles and materials based impact reactive projectiles are described. In one embodiment, a projectile includes a projectile core and a tip. The projectile core may include a core base and a central recess that extends from a leading circumferential rim of the projectile core to the core base. The projectile core may further include projectile fingers each separated by a kerf, extending longitudinally from the core base to the leading circumferential rim, and extending radially apart between an outer periphery of the central recess to an outer periphery surface of the core. Depending at least in part upon the type of materials which the projectile is formed from, upon impact, the projectile fingers and core base of the projectile may fracture apart without a slug remaining. Alternatively, the projectile fingers may bloom out, expanding the cross sectional area of the projectile, and slowing the projectile.
