FIELD: chemistry.
SUBSTANCE: invention relates to preparation of pellet powder for large-calibre machine guns and 30 mm air guns. The method involves preparation powder varnish in an aqueous medium in the presence of 1 pts. wt pyroxyline 1 Pl or powder mass, 8 … 10 pts. wt water and 2 … 3 pts. wt ethyl acetate, dispersing said varnish onto spherical particles with addition of 0.5...1.0 wt % protective colloid and 2.0...3.5 wt % sodium sulphate with respect to water to the dispersion medium, followed by removal of solvent.
EFFECT: method enables to obtain pellet powder with particle size of up to 2,5 mm.
