In this study, we performed combustion improvement test to reduce propellant charge weight of 40MM high-velocity grenade. Throughout the research, We have been varified Closed Bomb Test(CBT) is more reliable method for predicting Internal Ballisitcs than 5.56mm rifle tests. With improvement of propellant manufacturing process, we confirmed similar level of propellants charge weight to the U.S. 40MM high-velocity grenade. This paper suggest quality and safety improvement of 40MM high-velocity grenade, using Closed Bomb Test evaluation method.
