Best example of how much rifle movement and its direction is before the bullet leaves the barrel is hot gunning the same rifle in a prone match. The same 30 caliber magnum match rifle used by 4 people will easily have a 1.5 MOA spread in sight settings for a given range zero. That's because the rifle moves differently with each shooter 'cause they don't all hold it exactly the same way.
No, it ain't how folks look through sights. Light from the target goes through the sights the same way for everybody. That light and those sights do not know who's on the rifle to shoot it; they perform exactly the same way for each person.
