LOL, I really don't think it will be a guess, bullet impact will go one way or the other. I'm trying to imagine the rifle locked down in a vise and zeroed. Then raise the scope with a 1/2" spacer. (No dials have been adjusted) Now reposition the rifle so the crosshair is back on the bull, (still not adjusting the dials), where will the bullet impact, high or low?? Keep in mind that no adjustments have been made.
