Abstract

A full metal jacket hollow point bullet is disclosed which has the jacket extending fully within the hollow open front end of the bullet. A plurality of radial slits through the jacket within the hollow front end extend from the axis to the mouth of the hollow front end. These slits form prongs therebetween which project outward upon upset of the bullet in soft tissue.

a malleable metal body symmetrical about an axis therethrough, said body having a recess in one end forming an open cavity having a mouth and a pointed apex centered on said axis;

a metal jacket over a major portion of said body completely enclosing said one end and said recess, said jacket extending fully into said one end, said jacket in said end having a plurality of radially spaced slits forming petals therebetween in said jacket extending only from said pointed apex to said mouth, said petals each having a hardened transition region about said mouth and a pointed prong terminating at said pointed apex, said transition region being harder than any other portion of said bullet jacket and said body.
