Often times dove shooting is like trying to hit a curveball in the dark.
I've never done it, but I hear that it is some hard shooting.
Wing shooting with a shotgun, or shooting a flying target, is much different that shooting a still target with a rifle (like a deer). Shooting a still target, you look at the target, then look at the sight on the barrel of your gun, and you put the sight of the target. Many will shut 1 eye, the non dominate eye. This works for shooting a still target, but does not work well with flying targets.
Wing shooting, you shoot with both eyes open, and you always keep your eyes focused on the bird, and never look at the sight on your barrel. If you take your eyes off the bird to look at the sight on the barrel, you will miss the shot. Like hitting a baseball, do not take your eyes off the ball, same thing with wing shooting, do not take your eyes off the bird.
The reason for this is eye focus. Like a baseball, when that ball comes out of the pitchers hand, it is a blur at first, then your eyes slowly focus on the ball, as it gets closer and your eyes have time to focus, it becomes less a blur. If you take your eyes off the ball, you are doomed, no way your eyes will have time to refocus on the ball again. To use a football analogy, its like a receiver taking his eyes off the ball to see where he wants to run, or looking at an in coming defender, mostly likely he will miss that catch, eyes just do not have time to refocus on the ball.
When you are young, your eye focus is much better, you can get away with bad wing shooting methods, but there will come a time, like in your 40's, those eyes slow down big time, and all of sudden you cannot hit crap and you do not know why. If you want to get into wing shooting, like sking, take lessons from a pro, and learn how to shoot right.
