i have always done the same, both eyes open and follow the bird or what ever your shootn at, the big thing is follow through alot of times when you know your lead is good but for some reason your behind it could be as simple as slowing down your swing before the shot, i aggree with others when you over think things thats when they get messed up, instinct, go from the gut, breath normal and follow through, when it comes to rifles though it becomes a differant set of rules, the absolute most important is trigger squezze and breathing right... good luck to ya sir..
