Mr. Stringer and all: I have a Leupold Vari-X III 4.5-14 scope and have a small problem. I was told by a friend that you can "set" the scope turrets by loosening the small allen screws and when you have your initial zero, you spin the turret to that setting and retighten the screws. Can this be done? If so can all of you enlighten me ? Thanks
