The temperature coefficient of a gun propellant could be reduced by applying an appropriate surface coating material. The burning rates of those propellants do not very strongly depend on the propellant temperature. It is a good method to increase the muzzle velocity of gun ammunitions by utilizing the permissible maximum pressure in the gun barrel independent of the propellant temperature. During this study, properties of surface coated propellants were confirmed by results in tests of a closed bomb and 40mm Gun firing, and confirmed that production of coating propellant could be possible.
