ABSTRACT:
The present invention relates generally to small arms bullets and relates in particular to frangible bullets and ordinance which fragments following penetration of a variety of obstacles prior to encountering the intended target zone. The disclosure relates specifically to small arms bullets which have a high likelihood of fragmentation after target zone penetration causing a significant crush cavity following passage through obstacles including clothing, glass, building materials and other structures. The disclosed bullet design is produced in a simple and inexpensive process, provides high accuracy and fragmentation and penetration in a 5 to 15 inch target zone, at either sonic or subsonic velocities, following penetration of shielding obstacles. The bullet disclosed is of a weight and design which will permit operation at sonic or subsonic velocities, without jamming, in civilian and military small arms including automatic weapons. The disclosure also applies to military ordinance and armor piercing munitions where fragmentation following obstacle penetration is intended.
