Product Improvement Test of Cartridge, 81-mm, M374 with Modified Ignition - Propellant System and Reduced Bourrelet.
Abstract
A product improvement test was conducted on an 81-mm cartridge, M374, which mated a modified ignition system (XM285 ignition cartridge and small-hole boom) with waterproof (Celcon/silk) propellant bags. Various tests were conducted to determine if the modifications provided moisture protection without introducing undesirable side effects. A slight velocity degradation resulted when the test round was subjected to the rain test; however, no extremely short round (less than 80% range) occurred.
