ABSTRACT:
A rifle or handgun bullet having a base and a leading end of ogival shape extending for a portion of its length is divided into a plurality of sections by parting lines extending radially from the central axis and terminating a short distance from the outer wall, whereby the sections are joined by relatively thin webs at their outer edges. The parting lines extend longitudinally from the leading end through at least the ogival portion to as much as 90% of the length of the bullet. Upon impact with a lubricious target the sections separate from one another and from the base, i.e., the portion into which the parting lines do not extend. The bullet is fabricated in a two-stage operation, first forcing a punch longitudinally into a cylindrical slug of malleable metal contained within a die, and then compressing the slug radially inwardly to force essentially all air from the spaces formed by the punch, thereby and forming the ogival leading end.
