Development of a 20mm Plastic Frangible Projectile.

Abstract

This report describes a program to develop, fabricate, test, and subsequently deliver a quantity of 20mm plastic frangible projectiles designed to replace current monolithic all-metal target practice projectiles. The projectile comprises a stack of steel wafers excapsulated within a plastic shell and is designed to disintegrate upon target impact. Presented in the report are the fabrication and test of several different projectile configurations, the design and fabrication of an automatic nose and body mold, and the delivery of 900 assembled cartridges and 100 projectiles. At the completion of the program the projectile evolved is capable of being fired from a standard 20mm Mann barrel at standard muzzle velocities (on the order of 3300 fps). In all cases the projectiles break up on impact. (Author, modified-PL)
