RE: the shot.......
Mauser,
Try this... take a split second to think about something else. Like the score of a ball game the night before, your boss' face, the workings of a harmonic drive, anything other than hunting. It's hard at first but it really helps you get back into focus. Kinda like panning back when the picture gets blury on a camera. Don't take too long doing this or you'll miss anyway.
