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.
