FIELD: weapons and ammunition.SUBSTANCE: proposed charge consists of spherical powder with particle size of 0.4-0.8 mm. Said charge is arranged inside encapsulated case with bullet. Said charge is made of spherical powder elements consisting of nitrocellulose containing nitrogen oxide in amount of 213.0?214.5 ml NO/g, 10.0?13.0 wt % of nitroglycerine, 0.1?0.3 wt % mollite II, 0.3?0.7 wt % of diphenylamine wit bulk density of at least 0.960 kg/dm, 4.0-5.0 wt % of mollite I and 2.0-4.0 wt % of dinitrotoluene retarded from the surface, 0.1-0.3 wt % of graphite graphitised from the surface with 0.2?0.6 wt % of moisture and 0.1?0.9 wt % of ethyl acetate. Weight fraction of undersize 0.8 mm powder and oversize 0.4 mm powder makes at least 95 %. Weight fraction of oversize 0.8 mm powder and undersize 0.4 mm powder makes at least 5%.EFFECT: stable ballistic characteristics.1 dwg, 1 tbl, 5 ex |
