From Wikipedia, the free encyclopedia:
"6.5x55mm or 6.5x55mm SE (C.I.P.) (also known as 6.5x55mm Krag, 6.5x55mm Swedish Mauser or 6,5x55mm Mauser) is a rifle cartridge developed in 1891 for use in the new rifles then under consideration by the Swedish-Norwegian Kingdom. The two nations had independent armies and the normal procedure at that time was for the respective governments to use the same ammunition and then purchase small arms of their choice. Norway adopted the Krag-Jørgensen rifle, while Sweden adopted a Mauser rifle design
Early ammunition was loaded with a 10.1 gram (156 grain) long round-nosed bullet (B-projectile) with a muzzle velocity of 700 m/s (2300 ft/s), while later rounds used a 9 gram (139 grain) spitzer bullet (D-projectile) with a muzzle velocity of 870 m/s (2854 ft/s).
The 6.5x55mm cartridge is highly esteemed as a hunting round in Europe, Scandinavia, and North America. It is used for harvesting most kind of game including elk, moose and brown bear in Sweden and Norway, while in Canada and the United States it is used for taking deer and other medium-sized game. Sportsmen who favor the round laud the combination of low recoil coupled with the cartridge's inherent accuracy and superb penetrative qualities.
European rifle makers including Sauer, CZ, Steyr and Mauser offer sporting rifles chambered for this cartridge, as does the Finnish arms manufacturer SAKO/Tikka, while ammunition manufacturers such as Norma, Lapua and Hornady offer loadings of the 6.5x55mm round that are designed for use only in modern hunting rifles that can tolerate higher chamber pressures. These modern loadings should never be used in older military rifles."
