context_page_description: The RML 25-pounder gun was a British rifled muzzle-loading light siege gun and gun of position designed in 1871. It was intended to be an intermediate gun between the 16-pounder and 40-pounder Rifled Muzzle Loading guns. It was part of a series of guns designed after the British military reverted to rifled muzzle-loading artillery until a more satisfactory breech-loading system than that of the Armstrong guns was developed.
context_section_description: The gun consisted of a central toughened steel "A" tube surrounded by two wrought-iron coils. Rifling was the "Woolwich" pattern of three broad grooves, with a uniform twist of 1 turn in 35 calibres (i.e. in 166.25 inches).
  They were mounted on semi-mobile field carriages, with limbers which enabled them to be moved and mounted in either field fortifications or permanent fortifications.
  The guns used black powder charges in silk bags to fire three types of ammunition – common shell, shrapnel shell or case shot. A copper vent towards the end of the bore of the gun enabled friction tubes to be used to fire the gun.
