“Trapshooting is a specific form of clay target shooting. Trapshooting is a game of movement, action and split-second timing. It requires the accuracy and skill to repeatedly aim, fire and break the 4 1/4 inch disc which are hurled through the air at a speed of 42mph, simulating the flight path of a bird fleeing a hunter.”
