A new nitroguanidine propellant which is ballistically and physically superior to standard M15 propellant and requires 50% less final mixing time has been developed.nThe new propellant has been found to have better ballistic uniformity than M15 over a wide range of test conditions; its temperature and pressure dependence are significantly less; and it produces less flash and is at least as smokeless as M15 propellant.
