Depending on what I am shooting will depend on what style I shoot. On decoying birds I pick the spot where I think the bird will be aim at that spot and pull the trigger. With skeet I pick a spot on the supposed trajectory point at it and wait till the clay reaches it and then pull the trigger. On this method there needs to be some calculation for lead meaning shooting before the clay reaches the point of aim. With trap I shoot the traditional way. Swing through and pull the trigger. I have a cross eye dominance and can not shoot with both eyes open. I think like Brent I have developed a squint method of shooting. I keep both eyes open till I reach the target then squint my left eye (right hand shooter) to fine tune and pull the trigger. Or I think that is what happens. I shoot so fast that I can not really determine exactly what is happening and would need a video camera to see what is going on.
