6.5×55mm Swedish
The cartridge was developed in a joint Norwegian and Swedish effort starting in 1891 for use in the new service rifles then under consideration by the United Kingdoms of Sweden and Norway.The two nations had independent armies and consequently the normal procedure at the time was for their respective governments to use the same ammunition and then purchase small arms of their choice.Thanks in part to its relatively roomy case which was designed for loading long, heavy 6.71 mm (0.264 in) bullets, and a 12.2 mm (0.480 in) diameter bolt face, it has proven more successful than other first-generation smokeless-powder military cartridges of similar bullet calibers, such as the 6×60mm US Navy, 6.5×54mm Mannlicher–Schönauer, 6.5×53mmR Dutch Mannlicher, 6.5×52mm Carcano and 6.5×50mm Arisaka.[14] In 1990, a specification was introduced along with the Scandinavian target rifle by the Scandinavian shooting associations DDS, DFS and FSR with the designation 6.5 × 55 mm SKAN which tightened up the original tolerances (minimum and maximum dimensions) of the 1893 design standard, added a slightly longer chamber space for the neck for increased safety with untrimmed reloads, and increased the pressure rating.While the 6.5×57mm and 6.5×55mm both require a long-action receiver, the shorter .260 Remington being (based on the .308 Winchester cartridge) can be fitted to a short bolt-action format.Other 21st century cartridges, like the 6.5×47mm Lapua and the 6.5mm Creedmoor that have entered the market also are able to provide similar performance to factory 6.5×55mm ammunition.Despite this finding, the Swedish weapon-historian Josef Alm repeated the rumor in a book in the 1930s, leading many to believe that there was a significant difference between the ammunition manufactured in Norway and Sweden.Otherwise its measurements is almost identical to the original standard except for a slightly longer chamber space for the neck by less than a millimeter.6.5 mm sk ptr m/94 prj m/94 was the standard service ball cartridge up to the early phase of World War II and Norwegian occupation by Germany in 1940.Sweden, which remained neutral during World War II, decided during the early 1940s to develop a new ball projectile for the 6.5 mm m/94 cartridge intended for sniping and sharpshooting, specifically for weapons such as the m/41 sniper rifle.Swedish blanks or lös patron were loaded with bullet shaped wooden projectiles that were painted red.It was used in a dedicated rifle grenade launcher based on the Remington m/67-89 (originally chambered for 8x58RD) called Krevadkarbin m/16 (blast carbine m/16).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.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.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.[34] 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 380.00 MPa (55,114 psi) Pmax piezo pressure loadings should never be used in the Krag–Jørgensen or Swedish Mauser or similar older rifles.Because 6.5 mm (.264 in) bullets have relatively high ballistic coefficients, the 6.5×55mm has seen success in long range target matches of 300–1,000 m (328–1,094 yd).The Ackley Improved family of wildcat cartridges is designed to be easily made by rechambering existing firearms, and fireforming the ammunition to decrease body taper and increase shoulder angle, resulting in a higher case capacity.
