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.

1. A cartridge comprising a projectile and a case, a front end of the case having a case mouth, the projectile having a tip and a circumferential front guide band, the tip merging into the front guide band, the projectile having a circumferential case mouth receiving space directly adjoining the front guide band and extending in an axial direction of the projectile toward a base of the projectile, the projectile having a circumferential rear guide band between the case mouth receiving space and the base of the projectile, the front guide band and the rear guide band defining an outside diameter of the projectile, the case mouth engaging the projectile in the case mouth receiving space, an exposed portion of the case mouth receiving space extending in the axial direction of the projectile being situated between the front guide band and the case mouth, and the case mouth not completely filling the case mouth receiving space in the direction of the tip of the projectile. 2. The cartridge according to claim 1, characterized in that the exposed portion of the case mouth receiving space is sealed off with a sealant. 3. The cartridge according to claim 1, characterized in that the tip merges via one or more shapes into the front guide band on the outside diameter of the projectile, in an ogival or conical manner. 4. The cartridge according to claim 1, characterized in that the exposed portion of the case mouth receiving space merges into the front guide band in a concave, convex, or linear manner. 5. The cartridge according to claim 4, characterized in that the exposed portion of the case mouth receiving space merges linearly into the front guide band at an angle of less than or equal to 16 degrees with respect to an axis of the projectile. 6. The cartridge according to claim 1, characterized in that the projectile transitions from a radially lowest location in the case mouth receiving space toward a rear of the projectile, via one or more shapes, in a concave, convex, or linear manner, to the outside diameter of the projectile. 7. The cartridge according to claim 1, characterized in that a receiving space containing a material that produces a tracer upon initiation is situated at a rear of the projectile. 8. The cartridge according to claim 1, characterized in that a borehole, which is coaxial with respect to an axis of the projectile, is provided in the projectile, the borehole being open toward the tip of the projectile, and a projectile core made of tungsten carbide is situated in the borehole, and the borehole is dosed by a projectile tip insert made of titanium, an outer shell of the projectile tip insert being a part of the tip of the projectile. 9. The cartridge according to claim 2, characterized in that the sealant comprises a lacquer. 10. The cartridge according to claim 6, characterized the radially lowest location in the case mouth receiving space is a field diameter or smaller. 11. A cartridge comprising: a projectile including a tip, a circumferential front guide band, and a circumferential rear guide band, the projectile further including a circumferential case mouth receiving space extending in an axial direction of the projectile toward a base of the projectile, the case mouth receiving space being disposed between the front guide band and the rear guide band, and the front guide band and the rear guide band defining an outside diameter of the projectile, anda case, a front end of the case including a case mouth, the case mouth engaging the projectile in the case mouth receiving space, the case mouth not completely covering the case mouth receiving space, and an exposed portion of the case mouth receiving space extending between the front guide band and the case mouth.
