20-Pounder Parrott Rifle

20-pdr. Parrott
The Parrott rifles were developed by Robert P. Parrott, and patented in 1861. They were easy to manufacture, inexpensive, and accurate. Parrott rifles are most readily identified by the wrought iron, reinforcing band that was shrink-fitted around the breech. The 20-pounder Parrott used shell, spherical case, and canister. While throwing a heavier shell, the 20-pounder's range was not significantly different from the 10-pounder version.
