The invention relates to a
projectile body for a firearm, in particular for a handgun, for forming a composite
projectile, in particular a hunting
projectile, with a projectile axis, wherein the projectile body has an outer surface, a front and a rear and is accelerated along the projectile axis towards the front by means of a
gas pressure acting on the rear for firing at a target and is driven with the front along a firing direction through a
barrel of the firearm towards the target, wherein the outer surface bears against an inner side of the
barrel during firing and seals the
gas pressure, wherein a joining receptacle is arranged on the front.wherein an active element can be mechanically fixed to the projectile body by means of an engagement of the active element corresponding to the joining receptacle by bringing the engagement of the joining element into contact with the joining receptacle along the projectile axis. The invention further relates to an active element, a projectile, a
cartridge, and methods for manufacturing a projectile and a
cartridge.
