[QUOTE="westcliffe01, post: 863899, member: 35183"] If you ever dial, it should always be in the same direction, since every mechanism has backlash. So for instance, assume your scope has 8 min up dialed in and you would like to check your zero: Dial down to zero, then go to -2. Then stop and dial back up from -2 to zero. So to get to zero, you dialed UP from -2. Now if verifying your drop, as long as you rotate the turret UP, all is good. If you get to +12 and find you need +11, dial down to +9, then back up to +11. This way you reach your target adjustment by always dialing in the same direction. You will have to figure out how much backlash your turrets have and if that is acceptable to you. The same process has to be used for the windage turret too. You just have to decide if you go to target value while dialing left or right. Pick one way and be consistent. Take note of where your turrets are currently adjusted, then re-zero them using the technique described above, where you dial to the value it is currently set to in the up and left direction for example (a minimum movement of 2 min to reach the final value). Then check where the scope is really zeroed. Then shoot a 6 min box pattern at 100 yards by dialing the scope "normally" and then after re-zeroing shoot them using the backlash techniques described. Many people will find it a confusing concept and for them a new scope with precise reliable turrets is the only solution. Perhaps, (if there is 2+ min of backlash) the scope needs to be repaired if you trust the manufacturer to really fix the problem. [/QUOTE]
