10 metre air rifle is a International Shooting Sports Federation (ISSF) shooting event, shot over a distance of 10 metres (10.9 yd) from a standing position with a 4.5 mm (0.177 in) calibre air rifle with a maximum weight of 5.5 kg (12.1 lbs). The use of specialised clothing is allowed to enhance the stability of the shooting position. It is one of the ISSF governed shooting events included in the Olympic games.
The course of fire is 60 shots within 105 minutes for men, and 40 shots within 75 minutes for women. During this phase a maximum of 10 points are awarded for each shot. The top eight shooters follow this with a final 10 shots – each scored to a maximum of 10.9 – with the cumulative score determining the winner. The maximum of 10.9 is derived from an additional set of 10 rings within the center 10 point circle, increasing in 0.1 point value as the rings approach the center.
Shots are fired from the standing position only, as opposed to some other airgun shooting disciplines such as for three positions (popular in the United States) or in disabled sports.
The major competitions are the Olympic Games every four years and the ISSF World Shooting Championships every four years. In addition, the event is included in the ISSF World Cup and in continental championships, as well as in many other international and national competitions. It is an indoor sport, and on the highest level electronic targets are used instead of the traditional paper targets.
Scores in 10 m Air Rifle have improved rapidly during the last few decades and today top competitors sometimes achieve maximum results ("full marks") for the initial phase (600 for men and 400 for women). The majority of these full marks were achieved at non directly ISSF supervised international and national-level matches and championships, where official ISSF recognized world records can not be set. This leads to many national records in fact being equal to the world records.

Equipment
For the 10 metre air rifle and air pistol disciplines match diabolo pellets are used. These pellets have wadcutter heads, meaning the front is (nearly) flat, that leave clean round holes in paper targets for easy scoring. Match pellets are offered in tins and more elaborate packaging’s that avoid deformation and other damage that could impair their uniformity. Especially air rifle shooters are encouraged to perform shooting group tests with their gun clamped in a machine rest to establish which particular match pellet type performs best for their particular air gun.1 To facilitate maximum performance out of various air guns the leading match pellet manufacturers produce pellets with graduated "head sizes", which means the pellets are offered with front diameters from 4.48 mm up to 4.51 mm.
The occurrence of full marks scores is mainly due to the continuous development of the employed match air rifles from spring-piston type designs into single-stroke pneumatic and pre-charged pneumatic (PCP) designs. Modern PCP match rifles from the leading manufacturers all feature fast lock times, shoot practically recoilless and vibration free, exhibit minimal movement and balance shifts and can be tailored by an adjustable stock and various accessories to the individual shooters personal preferences to promote comfortable and accurate shooting from a standing position. Combined with appropriate match pellets these rifles produce a consistent 10 ring performance, so a non maximal result during the initial phase can be attributed to the participant.
