The free rifle is a group of events held at the Olympics, beginning in 1896 and continuing to the current programme.
Current nomenclature drops the "free" and refers to the event type as the "rifle."
The 300 m rifle prone is a shooting discipline held at the world championships but never consistently at the Olympics.
In 1896, a 300-meter free rifle event was held without position requirements.
In 1900, medals were awarded for each of the three positions in the 300-metre free rifle competition, using the scores from the full individual event.
