FIELD: blasting.
SUBSTANCE: method is proposed for production of spherical powder for a sport hunting cartridge 30 CARBINE (7.62x33), including preparation of a powder varnish in process of mixing 1 wt part of nitrocellulose jointly with diphenylamine, technical carbon or graphite and dissolvent - ethyl acetate in a water medium, dispersion of varnish into spherical particles and removal of the dissolvent from powder elements in process of heating due to thermal exposure of the system from the coolant in the reactor's jacket. Nitrocellulose is a fine-grained non-moderated pyroxilic powder of VTM type with an expired warranty shelf life and a ballistite powder of NBl or NBpl types with an expired warranty shelf life.
EFFECT: invention provides for required ballistite properties of spherical powder in a sport hunting cartridge.
