Impact Testing with the Darts from Calber .50 AP Bullets

Abstract

This report describes in detail a method of testing samples of armor with the darts from caliber .50 AP bullets. Improvements in apparatus and technique have been made since such tests were used with caliber .30 AP bullets, reference (b), for another purpose. By use of the equipment and methods described in this report, 1/2" armor samples may be subjected to high speed penetration by a hardened tungsten stool dart, 0.427" diameter, 412 grains weight, and the impact velocity required for penetration measured to an accuracy of at least 1
