Sporting clays is a form of clay pigeon shooting, often described as "golf with a shotgun" because a typical course includes from 10 to 15 different shooting stations laid out over natural terrain. For safety, the course size is often no smaller than 35 acres (140,000 m2).
Unlike trap and skeet, which are games of repeatable target presentations, sporting clays simulates the unpredictability of live-quarry shooting, offering a great variety of trajectories, angles, speeds, elevations, distances, and target sizes.
A typical course consists of 10 to 15 stations, with each station presenting targets from trap machines. Usually 5 to 10 targets are shot at each station by a squad of up to six shooters for a total outing of 50 to 100 targets per person. Targets are thrown as singles and pairs. A pair of targets may be thrown as a true pair (or sim pair, i.e., thrown at the same time), as a following pair (thrown sequentially), or on report (the second clay launched on the report of the shooter’s gun). Numerous hunting conditions can be simulated by combining various speeds and angles with different types of clay targets. Each station is unique. Throughout a course, the shooters might see targets crossing from either side, coming inward, going outward, flying straight up, rolling on the ground, arcing high in the air, or thrown from towers. The possible target presentations are limited only by safety considerations, the terrain, and the imagination of the course designer. The configuration of the stations is often changed to maintain interest for the shooters and for environmental preservation of the course.
