The British Army officially adopted the breechloading Martini-Henry rifle in 1871, and it served valiantly throughout several wars, but it was not without issue. The main problem with the Martini-Henry was that it was single-shot, and thus made redundant almost as soon as it was adopted, thanks to the advent of the magazine-fed rifle. It was withdrawn from service in the late 1880s and replaced by the 10-shot Lee-Metford, the predecessor to the Lee-Enfield.
During its service lifetime, however, some attempts were made to convert the Martini-Henry into a magazine-fed rifle. Being a breechloader, this was difficult - but it proved possible. Charles Greville Harston of Toronto managed to create a spring-loaded magazine that would feed rounds into the breech of the Martini-Henry, thought the user would have to keep the rifle steady to avoid cartridges accidentally falling out. Another design incorporated a rotary drum magazine that fed rounds into the breech through gravity. Ultimately it was more convenient to adopt an entirely new rifle than to convert every existing Martini-Henry.
