I saw a thing on youtube that said if you are left-eye dominant but shooting right-handed, it becomes difficult to line things up properly with both eyes open. I am ambidextrous, which for me means equally uncoordinated with both hands--but definitely left eye dominant and a right handed shooter.
Was the youtube video hogwash that I should ignore, or is there some means of compensation (closing the left eye, maybe) or am I doomed never to have a tight shot group?
