Abstract : This invention relates to an improved ammunition propellant composition and method for reducing gun member wear erosion flash and cook-off through use of an additive comprising a mixture of a super water absorbent starch modified polyacrylonitrile which has been subjected to alkaline saponification and water. The wear reducing additive is preferably formed into sheets which can be used with propellants selected from the group consisting of bagged propelling charges and cartridge cased propellants.
