Abstract: An offensive charge intended for the manufacture of a cartridge for firing with a firearm does not contain lead. It is made of multiple projectiles (10), in which the projectiles are formed of at least two substantially spherical pellets (5) connected to one another by a metal connecting wire (6) of fixed predetermined length, the pellets being made of an alloy containing tin and antimony. A cartridge containing such projectiles, and a method for the mass-production of these lead-free projectiles are also described.
