After having missed several shots last year I figured in the off season I would get to the range and shoot some sporting clays. After a few times out I think I've figured out the problem. I think my left eye is becoming stronger then my right. Or it could be that my right eye fatigues quickly. I was always taught to keep both eyes open. But I found that keeping my left eye open is setting my shot off. Anyone else have this problem, and what do you do about it (other then close your left eye)?
