FIELD: chemistry.
SUBSTANCE: invention relates to production of pellet powder for small arms, particularly for 12, 16, 20 calibre smooth-bore hunting weapons. The powder contains pyroxylin, diphenylamine, graphite, ethyl acetate and moisture. The starting material is a mixture of pyroxylin with nitrogen oxide content 212.5-213.5 ml NO/g and pyroxylin with nitrogen oxide content 205.0-210.5 ml NO/g. The surface of the powder elements further contains vaseline oil which forms a moisture-proof coating which prevents penetration of moisture into the powder elements.
EFFECT: invention reduces hygroscopicity of pellet powder, as well as powder charge and muzzle pressure upon firing.
