The first shooter occupies station one, loads his gun with one shell, and calls for a bird. A single target emerges from the high house, and he tries to break it. Then he remains on the station and loads with two shells. Upon his call, a bird is thrown from each of the houses (known as a double), and he shoots at them.
All shooters in the group then do likewise, until they have all completed station one. The group moves on to each successive station, completing the required number of shots at each station (which varies) for all shooters, until everyone has completed each station. All shooters must complete each station, in shooting order, before anyone can advance to the next station.
