Target shooting by Rifle Volunteers in the National Rifle Association (NRA) matches was primarily with their arm of issue, which in the 1860s was the Pattern 1853 Enfield rifle. Following enquires to the NRA, in April 1861 Captain Edmond H. St. John-Mildmay, the Secretary, sought a ‘definition’ of the rifle. He wrote to Major-General Charles Hay, the Commandant and Inspector-General of Musketry, at the School of Musketry, Hythe (1853-1867). Hay responded and the NRA distributed the correspondence in May 1861 which was published in numerous newspapers of the time. Mildmay’s brief covering note to the newspaper editors, and Hay’s definition follow.
