The RML 16-pounder 12 cwt gun was a British Rifled, Muzzle Loading (RML) field artillery gun manufactured in England in the 19th century, which fired a projectile weighing approximately 16 pounds (7.3 kg).

The gun was rifled using the system developed by William Palliser, in which studs protruding from the side of the shell engaged with three spiral grooves in the barrel.

A flat surface was machined on top of the barrel for a clinometer to be used, enabling the gun to be levelled, or to provide an alternate method of indirect sighting.

[1] A number of different fuzes could be used enabling shells to either burst at a pre-determined time (and range), or on impact.

[2] It remained in front-line service with the Royal Artillery until the late 1880s when replaced by the 15-pounder Breech-Loading gun.

In 1906 the 1st Shropshire and Staffordshire Royal Garrison Artillery Volunteers took them to their annual camp in Bare, Morecambe.
