Leading the Targetâ€”Swing-Through Method
The two most common methods of leading targets at long distances are swing-through and sustained lead.
Point your shotgun at a moving target and swing with it. Increase the speed of the gun so that the muzzle passes the target and then fire. In other words, literally "swing through" the target and fire at a blank space in front of the target. Swing-through is the best technique for the beginning student.
