This is very simple! You play ball or hockey? Do you lock at the bat or the ball? Do you look at the mit or the ball? Do you look at the stick or the puck?
SEE, it is simple! Look at the target and not the sight when shooting shotgun! You need a proper fitting shotgun that will follow your eye. Where your eye is pointing is where the shotgun will shoot. Look AT the leading edge of the the target wether clay or bird. The rest is natural subconscience doing its work!
One more! "If you think, you stink!" Concentrate on the target and leave everything else in the garbage bin!
