Fullbore target rifle (TR) is a distinctively British and Commonwealth of Nations shooting discipline that evolved from Service rifle (SR) shooting in the late 1960s, and is governed by the rules of the National Rifle Association, UK (NRA).
To level the playing field as much as possible without stifling progress, and to make it possible for riflemen of all budgets to compete seriously, the rifle or all its component parts must be 'readily available in quantity'. This stipulation also keeps faith with the longstanding traditions of the NRA that the rifles used in competition should be of a type that, if necessary, could be readily used for homeland defence.
Fullbore Target Rifle involves prone position single shot precision shooting using 'iron' aperture sights at 'round bull' targets at distances from 300 to 1000 yards, with each shot being carefully scored and analysed. The usual calibre used is 7.62x51 NATO.
Fullbore Target Rifle Shooting has been established formally in the United States and is administered by the National Rifle Association of America NRA
Annual National Championship is currently held during September at the Wittington Center, Raton, NM
