1. A cartridge for arms used in military sport games, said cartridge comprising:
a cartridge case having a cylindrical body;
a propellant charge;
a tagging projectile; and
a primer cap,
wherein the cartridge case includes a nozzle intended to direct a portion of gas flow at the tagging projectile, said nozzle being fixedly provided in the body and positioned between a primer cap portion of the body and an opposite, mouth portion of the body,
wherein through holes to output the gas flow are made in the cylindrical body on a side of the primer cap, said through holes located downstream of the propellant charge, and
wherein a total area of the through holes is greater than an area of a minimum cross-section of the nozzle whereby a lesser gas flow is directed at the projectile via the nozzle and a greater portion of gas is outputted via the through holes.
