The Ordnance Society (https://ordnancesociety.org.uk/) has some unique artillery surveys on our website already, and we have just added another: a Worldwide Survey of British Rifled Muzzle Loading Guns. It includes many different variants of RMLs from the UK and all over the world and has 175 different guns listed. Most of the guns are linked to an excellent set of photos on ‘Flickr’.
An example:
11-inch Rifled Muzzle Loader Gun of 25 Tons Mk II
RGF No 30 1872
Only seven Mk I were made; the Mk II was adopted in 1871 and was constructed to the same design as the 9 in Mk IV.
It has 9 groove rifling (as do the 12 & 12.5 in guns); it fired a 548 lb projectile using 85lbs powder and could penetrate 13 in of armour plate at 1000 yds and 12 in at 2,000 yds
