In response to a request from the Office, Chief of Ordnance, and as a result of subsequent telephonic contacts with that office, tests have been conducted at this arsenal on various multi-layered assemblies of 17.5 ounce nylon duck. On the basis of resistance to perforation per unit weight the subject material, layered in an assembly equal in weight per unit area to .44 in of steel, is superior to all other fabrics tested at this arsenal to date with the possible exception of Nylon parachute cloth. As compared with Hadfield manganese steel of the quality currently procurable under Specification AXS-1170, this materials ballistic limit is about 300 feet-per-second lower under impact of projectile G-2 cal. .22, 17 grains and about 175 feet-per-second lower under impact od standard cal. .45 ball ammunition.
