[2] The International Shooting Sport Federation (ISSF) recognizes four three-position events.
Previously, this would consist of an additional 10 shots in the standing position, with the winner of the match being the shooter with the highest aggregate in both the qualification round and the final.
Both men and women shoot an additional 45 shots - 15 in each position - and qualification scores are discarded.
The 300m events are no longer in the Olympics primarily due to the price of constructing a 300m range.
[4] In the United States, a coalition of the Civilian Marksmanship Program (CMP), USA Shooting, JROTC, 4-H, and the American Legion recognize three position events for juniors using air rifles.
The CMP manages these matches for the National Three-Position Air Rifle Council, and recognizes the best junior shooters via the Distinguished program.
In between each string of shooting the range will generally give about 10-minute change over time to get ready for the next position.
When the range officer gives the command to commence firing the timer is started for the match being shot.
When the shooter has finished shooting all the shots for record they must wait for the range officer instructions to begin preparing for the next position.
Shooters generally use a kneeling roll and place it under the rear foot while aiming downrange.
There is a great fluctuation in scores and often depends on the stability and comfort of the shooters position.
[8] The sling is a belt like device that goes around the non-shooting bicep and wraps around the wrist and attaches to the handstop of the rifle.
If shooters fight their natural point of aim it is very difficult to stay stable and make a good shot.
