US Army 8-Inch Rifles in Martinsville, Virginia
US Army 8-Inch Rifle in Martinsville, Virginia
Two US Army 8-Inch Muzzle Loading Rifles are displayed outside the Old Henry County Courthouse in Martinsville, Virginia. These two guns were originally cast as 10-Inch Rodman smoothbores during or just after the American Civil War. In 1885 they were converted to 8-Inch Rifles at West Point Foundry. The conversion significantly improved the accuracy and hitting power of the old cast iron guns by boring them out to 13.5 inches and inserting a steel rifled sleeve of 8-Inches. Shot weight went from about 125 pounds to 180 pounds. With a propellent charge of 35 pounds, the converted guns were capable of penetrating 7 inches of iron armor at 1,000 yards.
