50 meter rifle three positions is an International Shooting Sport Federation event, a miniature version of 300 meter rifle three positions. It consists of the kneeling, prone, and standing positions, fired in that order, traditionally with 3×40 shots for men and 3×20 shots for women. In January 2018, the number of shots was equalised between genders with the Women's 3x20 being abolished in favour of a 3x40 match identical to the men's event. The caliber is .22 Long Rifle (5.6 mm).
