The targets we use in competition are the NSRA 2510BM/89 pattern, this 10 bull target is shot from the prone position (lying down). One shot is fired at each aiming mark and the maximum score that is possible is 100 (known in the sport as 'a Possible') The spot in the centre has no numerical value and is only used as a tie-breaker.
The 10 ring is the innermost white circle (smaller than a five pence piece) and these cards are scored using 'outward' gauging i.e. the outer edge of the shot hole that touches a scoring ring counts the lower, not the higher value. These targets are supplied by the NSRA and used for national and regional competitions.
The round nose of the .22 bullet punches a clean hole in to the target enabling them to be scored accurately by means of a plug gauge which has a flange the exact diameter of the bullet. The gauge is a push fit in the hole, which closes up after the bullet has passed through the target.
