I need to shim a rifle scope on an air rifle for my father as the scope has no more adjustment upwards but as I cant look down the bore and dont have a bore sighter. I cant remember if I shim the rear or the front scope ring in order I can get the pellet to strike higher on the target. Does anyone know please? My head is telling me the front scope ring but just want to check before I try incase im wrong.
Many thanks
