10 metre air rifle (N.B. For "Meter" in this article – read "Metre") is an International Shooting Sports Federation (ISSF) shooting event, shot at a bullseye target over a distance of using a calibre air rifle with a maximum weight of . It is one of the ISSF-governed shooting sports included in the Summer Olympics since the 1984 Los Angeles Games. Shots are fired from the

s are now being used instead of the traditional paper targets. Scores in 10 meter air rifle have improved rapidly during the last few decades. During the 1970s, technical advances in the employed match air rifles made the ISSF, known as the International Shooting Union or UIT (french: Union Internationale de Tir) back then, decide to significantly reduce the size of the 10 meter air rifle target to its current dimensions.

Rules

Until 2013, the maximum achievable aggregate score (qualification + final) was 709 for men (600 + 109.0) and 509 for women (400 + 109.0). The score for the qualification used integers (10 as highest score per shot) and the final stage included decimals (10.9 as highest score per shot). No top competitor achieved an official perfect aggregate score under these rules. Under rules introduced in 2013, the qualification scores that used to be combined with the finals scores for competition results were deleted, and the best eight competitors started all over again. In the 20 shots final, the highest achievable final score was 218.0 points. No top competitor achieved an official perfect final score under these rules. Rules introduced in 2018 ended the competition format differences between male and female athletes. Also, the final was changed to 24 shots (5 shots + 5 shots + 14 shots elimination phase). In the final, the highest achievable final score is 261.6 points. Up to 2020, no top competitor has achieved an official perfect final score under these rules. The current world record is 252.8 for men and 252.9 for women.

Qualification Round

Pre 2013 qualification rules

The course of fire was an unlimited number of sighter shots followed by 60 competition shots for men or 40 competition shots for women, all fired within 75 minutes for men or 50 minutes for women. During this initial or qualification phase a maximum of 10 points was awarded for each shot. Top competitors sometimes achieved maximum results (a "possible") for the initial or qualification 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 cannot be set. This leads to many national records in fact being equal to the world records.

2013 to 2018 qualification rules

The course of fire was 60 competition shots for men or 40 competition shots for women, all fired within 75 minutes for men or 50 minutes for women. During this initial or qualification phase a maximum of 10.9 points was awarded for each shot. The highest possible 60 shots score for men was 654.0 points and for woman 436.0 points.

2018 qualification rules

ISSF rules introduced in 2018 ended the gender differences, expanding the 40 shots qualification phase for women into 60 shots, setting the highest possible 60 shots score at 654.0 points.

Finals

Pre 2013 finals rules

The top eight shooters from the qualification round moved on to a finals event consisting of 10 shots – each decimal scored to a maximum of 10.9 – with the cumulative score determining the winner (qualification + finals score). Every scoring ring is 5 mm wide and sub-divided in 0.5 mm (≈ 0.1719

) increments in 10 "subrings". Like the other scoring rings the maximum of 10.9 is derived from an additional set of 10 "subrings" within the center 10-point circle, increasing in 0.1 point value as the rings approach the center of the target.

2013 to 2018 finals rules

In November 2012, The ISSF announced other finals rules. This finals rules had the best eight shooters starting from zero, eliminating the qualification scores that used to be combined with the finals scores for competition results. The format consisted of 20 finals shots scored in 0.1 point value as the rings approach the center of the target, setting the highest possible 20 shots score at 218.0 points.

2018 finals rules

Since 2018 the ISSF finals rules rank the eight best shooters starting from zero, eliminating the qualification scores. The format consists of 2 series of 5 shots each, to be fired within 250 seconds per series. This is followed by 14 single shots each fired on command with 50 seconds for each shot. Eliminations of the lowest scoring finalists begin after the tenth shot (series + first 2 single shots) and continue after every two shots, until the gold and silver medalists are decided. There is a total of 24 finals shots, setting the highest possible 24 shots score at 261.6 points. If there is a tie for the lowest ranking athlete to be eliminated, the tied athletes will fire additional tie-breaking single shots until the tie is broken.

Equipment

For the 10 meter air rifle and air pistol disciplines, match-grade diabolo pellets are used. These pellets are

s and allows easy gauging for scoring. Match pellets are offered in tins and more elaborate packagings that avoid deformation and other damage that could impair their uniformity. Match 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. 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 up to . However at higher and top competitive levels, even these variations are thought too coarse-grained and match pellets are ''batch-tested''; that is, the specific gun is mounted in a machine rest test rig and pellets from a specific production run on a specific machine with the same ingredients fed into the process (a ''batch'') are test-fired through the gun. Many different batches will be tested in this manner, and the pellets which give the smallest ''consistent'' group size without fliers (shots which fall outside of the main group) will be selected (small but inconsistent group sizes are not useful to a top competitor); and the shooter will then purchase several tens of thousands of pellets from that batch. Group sizes of diameter are theoretically possible, but practically shot groups of are considered highly competitive.Haendler & Natermann Finale Match Rifle
/ref> Unbatched ammunition, especially if the air gun is not regularly cleaned, is generally thought to be capable of only diameter group sizes. Batch-testing match pellets for a particular gun is not generally thought to be worthwhile until the shooter reaches a high proficiency level (around the 95% level ''i.e'' 570 for the qualification round). The occurrence of high scores in modern times is mainly due to the continuous development of the employed match air rifles from spring-piston type designs into single-stroke pneumatic and then regulated pre-charged pneumatic (PCP) designs.
