Abstract
With the aim of providing a 6.5 caliber cartridge for rifles having a casing which is suitable for both light and heavy projectiles without impairing accuracy and which results in an increase in the efficiency of the propellant charge, a reduction in the stress on the barrel and breech of the weapon, and the production of shorter and hence lighter weapons, as well as in an increase in the service life of the reloadable casing, a cartridge is proposed which has a reduced length of the virtually cylindrical region of the casing between the casing base and the transition into the casing neck as well as by an extremely flat transition into the casing neck has been developed along with a suitable cartridge chamber.
