Abstract: The invention relates to a cartridge of a firearm, comprising a cartridge case implemented in the manner of a bottleneck case for receiving a projectile, wherein the cartridge case has an overall length (L3) of 37.50 mm (1.4764?) to 40.50 mm (1.5945?), preferably of 38.50 mm (1.5157?) to 39.50 mm (1.5551?), particularly preferably of 39.00 mm (1.5354?), and the length of the case neck—case neck length (L3-L2)—is selected such that the ratio of the diameter (G1) of the projectile (8) to the case neck length (L3-L2) of the cartridge case is between 1.19 and 1.36, preferably between 1.26 and 1.36, and particularly preferably between 1.26 and 1.27. The invention further relates to a cartridge chamber, to a combination of breech and cartridge chamber of such a firearm, and to a firearm.
