20-pounder Parrott rifled muzzleloader
Common name: 20-pdr. Parrott
Description: The largest rifled field artillery piece in common service, the 20-pounder Parrott was made of cast iron with wrought iron breech reenforcement. It was an accurate but not wholly reliable weapon - it gained a reputation for sometimes bursting at the breech after prolonged firing. Because of its high weight and reputation for bursting, it was largely replaced by 10-pounder Parrots and 3-in Ordnance rifles after Antietam.
Confederate versions of the Parrott Rifles were built by the Noble Brothers Foundry and the Macon Arsenal in Georgia.
Employment at Sharpsburg: There were at least 22 20-pounder Parrotts in Federal Batteries at Antietam but none known to be in Confederate service at the Battle. Find units equipped with these.
Ammunition Used: solid bolt, case, common shell, cannister
Manufacturer: West Point Arsenal Where made: Cold Spring, New York Maximum Range: 1900 yards Barrel/Tube Length: 84 inches Bore: 3.67 inches Weight: 2925 pounds
Other notes: Weight figure is for gun carriage (1175 lb) + tube (1750 lb).
Max range is for 2 lb black powder charge behind a 20 pound solid shot at 5deg elevation.
