Springfield Model 1855

The Springfield Model 1855 was a rifled musket widely used in the American Civil War. It exploited the advantages of the new conical Minié ball, which could be deadly at over 1,000 yards (910 m). It was a standard infantry weapon for Union and Confederates alike, until the Springfield Model 1861 supplanted it, obviating the use of the insufficiently weather resistant Maynard tape primer.
