Traceable Frangible Projectile

Abstract

A frangible projectile useful in a round of gun ammunition wherein, upon striking a target, the projectile selectively disintegrates, leaving intact at least one portion or appurtenance of the projectile which is recoverable for purpose of identification of rifling markings thereon and / or other analysis.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 60 / 949,101; filed Jul. 11, 2007.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not ApplicableFIELD OF INVENTION[0003]This invention relates to the tracing of a spent bullet (projectile) to the gun from which the projectile was fired. More particularly, this invention relates to the traceability of a frangible projectile to the gun from which such frangible projectile was fired.BACKGROUND OF INVENTION[0004]Traceability of a spent projectile to the gun from which it was fired is a major factor in criminology. Commonly a projectile designed to be fired from a gun comprises a soft metal jacket housing a frangible core. When such projectile is fired from a gun having a rifled barrel, the rifling internal of the barrel imparts a “signature” to the outer surface of the jacket as the projectile moves through and out of the barrel. In a fully frangible pr...

AI Technical Summary

Benefits of technology

[0012]The disintegration-limiting factor may take on several forms, but in each form, the projectile is designed to disintegrate upon striking a target, such disintegration commencing at the leading end of the projectile and promulgating toward the trailing end of the projectile. Such limiter factor may be formed integrally of the jacket and / or may be in the form of an appurtenance supplied to the frangible core of the projectile. Such limiter factor effectively either retards or halts the promulgation of disintegration of the core and resultant intact survival of at least an appurtenance or a portion of the projectile disposed proximate the trailing end of the projectile, resulting in preservation of an intact recoverable portion of the projectile having rifling markings thereon.

Problems solved by technology

However, these fully frangible projectiles do not leave intact any portion of the projectile which is useful for identifying rifling markings thereon, if any.
