ABSTRACT:
The invention relates to cartridged ammunition, particularly blank ammunition, having a cartridge shell (3) and a projectile (2) placed therein. A propellant chamber (4) accommodating a pyrotechnic of a propellant charge (5) is disposed in the cartridge shell, such charge being ignitable by an ignition device (13) also containing pyrotechnic material that generates propellant gases that act on the base (8) of the projectile and propel the shot out of the cartridge shell. In order to prevent the pyrotechnic charges of the propellant charge and/or the ignition device from self-igniting at high ambient temperatures, particularly in a fire, thus tearing apart the cartridge shell and projectile and being flung away, an inert, meltable material is mixed into the pyrotechnic charges of the propellant charge and/or the ignition device. This material has a melting temperature that is lower than the self-ignition temperature of the pyrotechnic charge with the lowest ignition temperature and, upon melting, phlegmatises the pyrotechnic charges of the propellant charge and/or the ignition device.
