This report presents results of Phase II testing of a 30-mm steel cartridge case. The steel case was designed for consideration as an alternate to the standard aluminum 30-mm case because of the anticipated increase in projectile velocity and decrease in cost per case. This test was planned to demonstrate performance of the Phase II case design which was necessitated because of case failures in Phase I testing ADTC-TR-76-11. Case failures at the beginning of this test led to transformation of this effort into an investigation of different case designs. A total of 305 steel case rounds fired at the end of the test incorporated the final case designs tested. Of those fired, the optimal as determined by its performance case tested had a lacquer finish and weighed 0.51 pound. Forty-two of these rounds 21 at ambient temperature, 7 conditioned to -65 F, and 14 conditioned to 160 F were fired without failures. Author
