7×64mm
German hunting rifle cartridge / From Wikipedia, the free encyclopedia
The 7×64mm (also unofficially known as the 7×64mm Brenneke, though its designer's name was never officially added as a part of the cartridge name) is a rimless bottlenecked centerfire cartridge developed for hunting. As is customary in European cartridges, the 7 denotes the 7 mm bore diameter and the 64 denotes the 64 mm (2.5 in) case length. The 7×64mm is a popular hunting cartridge in Central Europe due to its 11.95 mm (0.470 in) case head diameter and 84 mm (3.3 in) overall length allowing it to easily be chambered in the Mauser 98 bolt-action rifle that was once standard German military issue.
