supaarcher, do you by chance shoot with both eyes open? my father had the weirdest thing happen to him this season. he shot at what he called a "dandy eight" only to miss 3 ft. to the left. after the deer left, he drew his bow and put his pins on exactly where the deer was standing. just on a hunch, (he shoots both eyes open) he closed his right eye and lined the pins up where the deer was standing with his left eye. Then he closed his left eye and looked through his peep by opened his right eye back up only to see that his bow was aiming right where his arrow flew three ft. to the left! simply, his left eye took over his vision. he has been right eye-dominant his entire life, has shot bows, shotguns, rifles, etc. with both eyes open without ever having a problem. but, for some unknown reason, that day, his right eye did not "dominate" his vision, his left eye did. could this be what is happening to you? did i explain myself correctly?
