Shooting events at the Olympics and Commonwealth Games fall into three general categories.
Competitors shoot with either rifles, pistols or shotguns.
The guns come in many different shapes and sizes, and the type of target also varies from event to event.
HOW THE EVENTS UNFOLD
In all pistol events, competitors earn points shooting at a 10-ring target. The winner is the one with the most points.
Pistol shooters use a standing position and must hold and fire the gun with one hand, with the wrist clearly free of support.
Scores range from one point for hitting the outside zone, to 10 for a hit in the 10 ring ('bull'). If a shot hits the line between two zones, the higher score is awarded.
There is a qualifying round and then, in the final, the 10 rings on the target are sub-divided into 10 score zones, with the highest score for a shot 10.9.
The final round and qualifying scores are added together to determine the winner.
