long rifle, m/38 (Model 1938) short rifle and m/41 (Model 1941) sniper rifle and the Ag m/42 semi-automatic rifle. The Swedish Mauser arms had a relatively tight 200 mm (1 in 7.87 in) twist rate optimized for stabilizing the relatively long heavy bullets used in the Swedish 6.5×55mm military service ammunition. It was also used in several light, medium and heavy machine guns such as the Schwarzlose, Browning BAR, Kg/1940 Light machine gun, Bren Gun, Browning M1917, Browning M1919 and FN MAG. The FN MAG was eventually returned to its original 7.62×51mm NATO chambering when the Swedish armed forces switched to that cartridge as its standard rifle cartridge for communality reasons following the adoption of the Heckler & Koch G3 in the early 1960s. Danish service In 1946 Denmark made a standard cartridge with two different bullets. The 6.5 mm skarppatroner m/46-ru had a rundspids (round tip) bullet (like the Swedish projektil m/94) for use with Danish Krag rifles by the Home Guard. The 6.5 mm skarppatroner m/46-sp had a spidsskarp (pointed tip) bullet (like the projektil m/41) for use in more modern firearms like the Swedish Mauser. Sporting use The 6.5×55mm cartridge is highly esteemed as a hunting round in Europe (particularly in Scandinavia), and North America. It is used for hunting most kind of game including moose in Scandinavia, while in most other countries it is used to hunt 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 due to the high obtainable sectional density. Despite its enduring popularity amongst a devoted niche of American sportsmen, U.S. rifle manufacturers have, for the most part, ignored the cartridge. As of 2014 there were at least four mainstream American arms manufacturers, Thompson Center, Barrett Firearms (Fieldcraft), Remington (Model 700), and Ruger producing a sporting rifle in chambered for the 6.5×55mm. European rifle makers including Blaser, CZ, Sauer & Sohn, Steyr, and Mauser Jagdwaffen GmbH offer sporting rifles chambered for this cartridge, as does the Finnish arms manufacturer SAKO/Tikka, and Japanese manufacturer Howa, while ammunition manufacturers such as Norma, Lapua, Prvi Partizan, RUAG Ammotec, Remington Arms, and Hornady offer loadings of the 6.5×55mm round that are designed for use only in modern hunting rifles that can tolerate higher chamber pressures. Finnish powder manufacturer Vihtavuori warns modern Pmax piezo pressure loadings should never be used
