The Model 1841 was replaced by the
minie ball firing
Springfield Model 1855, which became the standard issue weapon for regular army infantry, and ultimately the
Springfield Model 1861 and
Model 1863. Large-scale retooling of existing rifles were done to increase the bore to .58 inch to match the standfard round used by the Model 1855. Parts, locks, and stocks left in supply were matched with newly forged 40-inch barrels, and barrels were used to make new rifles of this pattern in .58 caliber. As well as this work being done at Harper's Ferry and Springfield it was done by contractors like Eli Whitney,
Remington, and Robbins, Kendall, and Lawrence Armory (RK&L) of Windsor, Vermont By the time of the
Civil War, the Mississippi Rifle was generally considered old-fashioned but effective. It was carried by some
Union troops up until 1863, though the
45th New York Infantry still used the rifle beyond
Gettysburg. Some
Confederate cavalry and
sharpshooter units continued to use the rifle until the end of the war, evidenced by surviving Confederate ordnance requisitions. The rifle also saw a long use on the western frontier in civilian hands as well as those of first nations. Both parties found it a reliable, accurate hunting and home defense weapon. ==See also==
