Remington Rolling Block is a family of breech-loading rifles that was produced from the mid-1860s into the early 20th century by E. Remington and Sons (later Remington Arms). The action was extremely strong, and could easily withstand the increased pressure of the new smokeless powders coming into use by the late 1880s.
These rifles were made in a variety of calibers, both rimfire and centerfire, including the 12.17x42 mm rimfire, 12.17x44 mm rimfire and 12.17x44 mm rimmed centerfire Swedish and Norwegian cartridges, .43 Spanish (11.15x58mmR), .50-70, .40-70, .45-70 and later in .22 caliber. Later models were produced in .30-06 Springfield, 7×57mm Mauser, and 8×50mmR Lebel.
