The 10-pounder Parrott rifle, Model 1861 was a muzzle-loading rifled cannon made of cast iron that was adopted by the United States Army in 1861 and often used in field artillery units during the American Civil War. Like other Parrott rifles, the gun breech was reinforced by a distinctive band made of wrought iron. The 10-pounder Parrott rifle was capable of firing shell, shrapnel shell (case shot), canister shot, or solid shot. Midway through the war, the Federal government discontinued the 2.9 in (74 mm) version in favor of a 3.0 in (76 mm) version. Despite the reinforcing band, the guns occasionally burst without warning, which endangered the gun crews. The Confederate States of America manufactured a number of successful copies of the gun.
