The cartridged ammunition comprises a projectile (11) and a cartridge case (10) receiving the latter. The cartridge case (10) contains a cartridge (12) limiting a high-pressure space (21) in which a propelling charge (14) is located. The cartridge (12) is surrounded by a low-pressure space (10a) limited by the inside walls of the cartridge case (10) and a part of the base of the projectile (11). At the rear of the projectile (11) a tracer composition (11b) is arranged in a tube (27) which protrudes through the upper wall of the cartridge (12) into the high-pressure space (21). Projectile and cartridge case are interconnected via a rated breaking point (12d). The pressure for expelling the projectile (11) from the cartridge case is supplied by the pressure both in the high-pressure space (21) and in the low-pressure space (10a). Upon expulsion the volume of the high-pressure space (21) is furthermore enlarged when the tracer composition is pulled out thereof. These measures avoid steep pressure peaks in the march of pressure upon expulsion of the projectile. At the same time, approximately the entire projectile volume is available for a service charge.

[ What is claimed:] [1.] Cartridged ammunition comprising a cartridge case for receiving an ignition charge and a projectile disposed in and connected to said cartridge case, the projectile having a service charge and a tracer composition positioned at a rear of the projectile, a cartridge located centrally in the cartridge case, said cartridge having a rated breaking point which connects the projectile to the cartridge, said cartridge defining a high-pressure space and containing a propelling charge, and a low pressure space surrounding the cartridge, said low pressure space being defined by inside walls of the cartridge case and a base of the projectile, said low pressure space being connected to said high pressure space by overflow openings, wherein the tracer composition is received in a tube protruding from a middle of a rear of said projectile and penetrating an upper wall of the cartridge, said tube being mounted in said upper wall substantially in an opening in a gastight and sliding fashion and protruding into the high pressure space, so that the tube is pulled out of the high pressure space to enlarge the volume of said high pressure space after the rated breaking point breaks open.
