I have my Millett Tac-1 scope mounted on my Tikka T3 SS Varmint rifle (.223 cal.) It is an excellent scope and I had it zeroed in at 100 yards. The turrets are supposed to be able to be set to zero by loosening a screw on top of the turrets once the scope is ranged in. I loosened the set screw on the elevation knob and tried to lift it and rotate to zero but it just cliked away and now I have to re-range the scope by firing at the range. Does anyone have this scope and how do you set the turrets to zero once it has been ranged in?
