A cartridge (1) comprises a cartridge case (2), which is closed at its rear end and contains a propellant charge (3) and a primer (7). The tip portion of the cartridge case defines a socket (4), which accommodates a full-bore projectile (5). The tip portion (2b), terminates adjacent to the nose of the projectile in an end face that is normal to the axis of the cartridge. That tip portion has an outside peripheral surface, which tapers with a substantially concave contour toward said forward end face. To provide a cartridge (1) which can easily be manufactured and can reliably be fired and can be gas-tightly inserted into the chamber of the firearm, the tip portion (2b) is formed in its rear end portion with a peripheral annular groove (6), which is open to the interior of the cartridge case and which contains the primer (7).
