About 250,000 Model 1842 Springfield single-shot muzzleloading smoothbores were made before 1856, at which time the US Army began rifling some of them. About 14,000 were converted by 1859. The .69 caliber rifle was found to be less accurate than the new .58 caliber rifles, however, and further rifling was halted.
