Improved Military Rifle (IMR) describes a series of tubular nitrocellulose smokeless powders evolved from World War I through World War II for loading military and commercial ammunition and sold to private citizens for reloading rifle ammunition for hunting and target shooting. IMR powders are coated with dinitrotoluene (DNT) to slow initial burning and graphite to minimize static electricity during blending and loading. They contain 0.6% diphenylamine as a stabilizer and 1% potassium sulfate to reduce muzzle flash.
