The event is in part meant to simulate the action of bird hunting. The shooter shoots from seven (7) positions on a semi-circle, and an 8th position halfway between stations 1 and 7. There are two houses that hold devices known as "traps" that launch the targets, one at each corner of the semi-circle. The traps launch the targets to a point 15 feet above ground and 18 feet outside of station 8. One trap launches targets from 10 feet above the ground ("high" house) and the other launches it from 3 feet above ground ("low" house). At stations 1 and 2, the shooter shoots at single targets launched from the high house and then the low house, then shoots a double where the two targets are launched simultaneously. At stations 3, 4, and 5, the shooter shoots at single targets launched from the high house and then the low house. At stations 6 and 7, the shooter shoots at single targets launched from the high house and then the low house, then shoots a double. At station 8, the shooter shoots one high target and one low target. The shooter must reshoot his first missed target, or if no targets are missed, must shoot his 25th shell at the low house station 8. This 25th shot was once referred to as the shooter's option as he was able to take it where he preferred. Now, to speed up rounds in competition, the shooter must shoot the low 8 twice for a perfect score.
