摘要： The invention relates to a cartridge having a projectile, and a case which is mounted on the projectile from behind and which has a case mouth at the front end, wherein the projectile has a tip, and at the rear this tip merges into a circumferential front guide band which defines the outside diameter of the projectile, and directly adjoining this front guide band in the direction of the projectile base, a circumferential case mouth receiving space which extends in the axial direction of the projectile and in which the case mouth engages is situated in the projectile. In order to reduce the twistless freebore to a minimum and build up the gas pressure early during firing, it is proposed that an exposed portion of the case mouth receiving space extending in the axial direction of the projectile is situated between the front guide band and the case mouth; i.e., the case mouth does not completely fill the case mouth receiving space in the direction of the nose of the projectile.
