American (ATA) Trap
Trap is the oldest shotgun shooting sport in America. Trapshooting derives its name from the device, called a trap, which throws clay targets into the air. Participants shoot at the clay targets thrown from a trap house located in front of the shooter. The trap rotates in a random sequence, presenting the shooter with a variety of going away shots, angling to the right, left and flying straightaway.
Trap is usually shot in squads of five shooters. A round of trap consists of 25 targets per shooter. A trap field has five positions, or stations, numbered consecutively from left to right. Five clay targets, sometimes referred to as "birds," are thrown for each shooter at each position, with one shot being fired at each bird. After firing five rounds in rotation, each squad member moves one station to his right, with the shooter on station five moving over to station one.
