Abstract:
Hollow point bullets and methods of manufacturing such bullets are herein disclosed. The disclosed bullets include a monolithic core encased by a metal jacket. The jacket includes a plurality of v-shaped channels formed on the inner surface of the sidewall of the jacket. The core includes a conical recess formed therein and a cavity in communication with the conical recess. The cavity formed in the core may have a cross-section shape defined by a plurality of points spaced equidistantly about the circumference of an imaginary circle. A plurality of stress risers may be formed in the core, each stress riser extending from the cavity to a v-shaped channel in coincidence with a point of the cross-section shape of the cavity.
