U.S. 3-inch Ordnance Rifle

The Yankee Three-inch rifle was a dead shot at any distance under a mile. They could hit the end of a flour barrel more often than miss, unless the gunner got rattled. This tribute was grudgingly given by a member of Lumsden’s Confederate battery while it was entrenched during the battles around Atlanta in 1864. A new forging and welding methods brought new promise for wrought iron. A pile of wrought iron rods 7/8″ X 7/8″ X 4-1/2 feet were welded together to form a mandrel. A long bar 3/4″ X 4-1/2′ was wound spirally around this by revolving the lathe, three successive layers were thus applied to the mandrel, each layer spiraling in a direction opposite of the previous one. A thin layer of staves was applied to the outside, and a plug driven to form the breech. Welding heat was then attained and the mass was rolled out to the length of seven feet. Trunnions were welded on and the gun was bored and rifled from the solid. The 3-inch Ordnance Rifle was the second most common rifled field gun found in the Union and Confederate armies. With a 1-lb. propellant charge, the 3-inch rifle fired a 9.5-lb. shot to 1830 yards at five degrees elevation. The 3-inch Ordnance rifle was probably the most popular field piece of the war. Our version is cast solid and then deep hole gun drilled and choice of a rifle liner (like the original) or a smooth bore liner is available.
