Shooting sport with moving targets.
A shotgun (usually 12-gauge) is used. The targets are clay disks (called pigeons) that are sprung into the air from a trap. A later variant is skeet shooting. Trapshooting's origins date to the 18th century, when marksmen shot at live pigeons released from cages or box traps. The modern clay-pigeon variety has been included in Olympic Games competition since 1900. A single trap throws 25 targets at varying angles; each competitor fires four 25-target rounds.
