 RML 6.3-inch howitzer

The RML 6.3-inch howitzer was a British rifled muzzle-loading "siege" or "position" howitzer/mortar proposed in 1874 and finally introduced in 1878 as a lighter version of the successful 8-inch howitzer that could be carried by the existing 40-pounder gun carriage.By 1880 the RML 6.3-inch was superseded by a longer 6.6-inch howitzer with higher muzzle velocity.
