Field Artillery No. 3
12-Pound Rifled James
This bronze gun was converted from a six-pound smoothbore to a 12-pound rifled gun at the beginning of the war.
Charles T. James of the Rhode Island militia developed a projectile
that could be used in any cannon specifically rifled for it (15
lands and grooves).
In actuality, other ammunition was often substituted.
The range at 5 degrees elevation was 1700 yards (one mile equals 1760 yards).
It used solid shot, shell, and canister. The tube weighed 886 lbs.
