High Quality Content by WIKIPEDIA articles! The Model 1867 Remington rolling block rifle was the first rifle using metallic cartridges to be adopted by the Swedish and Norwegian armies. Nominally it had a caliber of 4 decimal lines, but the actual caliber was 4.1 Swedish decimal lines or 3.88 Norwegian decimal lines (12.17 mm), and it fired a rimfire round with a 12.615 mm (.497 in) lead bullet. The 12.17 mm caliber was chosen because the Swedish army had approximately 30,000 new muzzle loading Model 1860 and breech-loading Model 1864 rifles in 12.17 mm caliber in stock, rifles that were suitable for conversion to Model 1867 rolling block rifles. With the exception of the first 10,000 rifles and 20,000 actions (for conversions of older rifles), which were made by Remington in the US, all Model 1867 Remington rolling block rifles and carbines were made under license in Sweden and Norway, by Carl Gustafs stads Gevarsfaktori and Husqvarna Vapenfabriks Aktiebolag in Sweden and by Kongsberg Vaapenfabrik in Norway, with the two Swedish manufacturers producing about 80% of the weapons.
