DEEP GROOVE PROJECTILE WITH LEADING CONVEX SURFACE FOLLOWED BY ABRUPT ANGLE SURFACE

Abstract

A firearm projectile is provided to promote a yaw effect on material entry by the projectile and to enhance wound channel formation on entered material. The firearm projectile comprises an elongated body, having a surface formed as a surface of revolution. It further consists of an ovoid forward portion and a cylindrical rear portion.

Claims

1. A firearm projectile comprising: an elongated body having a surface formed as a surface of revolution; the elongated body having a generally ovoid-shaped forward portion pointing in the direction of projectile travel; the elongated body having a rear portion having a forward-facing face attached behind the generally ovoid-shaped forward portion; and the generally ovoid-shaped forward portion having a reduced diameter portion adjacent to the rear portion.
