Various numbers of layers of 17-12 oz. nylon duck have been tested with the 34-grain fragment-simulating projectile developed at this arsenal. In accordance with instructions the ballistic limits of several plies of this material, as affixed to a dummy, were determined. In addition similar plies of this material mounted rigidly on a wooden ballistic frame were tested with the same projectile. The results of each series of tests appear in Table I in company with the estimated ballistic limits of good Hadfield manganese steel of equivalent weight pwe square foot.
