This paper deals with the forming technique of the oblate spherical powder and the feasibility of applying it to the large caliber gun propellant charge with high loading density. The free loading test results in simulated cartridge show that the use of oblate spherical powder could be applied to increase the loading density effectively. The 30mm antiaircraft gun firing test results by using the deterred oblate spherical powder show that the muzzle velocity increases 2.1% more than that of the standard cha...
