I use a different method. Initially I disregard the turret numbers. Though setting them at 0 windage and 1elevation is OK to start.
If you have a laser or other bore sighter then use that and turn the turrets until the reticle is on the red dot or zeroing point. This saves range time or getting on paper. again disregard the numbers as they will be adjusted at the range etc.
At the range start with a large paper target so you are sure to be on paper. Shoot a group. Move the turrets to adjust the POA to the POI. After that is complete.., then loosen the turret cap screws and move the ring number dial to 0 for windage and 1 if zeroing at 100 meters or half way if at 50 or so.
That is how I do it.
If the reticle is not in the center you will likely need to shim the scope in the mount etc.
If you run out of adjustment while zeroing (eg., elevation dial is at 0 already but still shooting high)., you will need to loosen the turret screws and move the dial to 3 or so.., to allow more adjustment. Start the zero from that point again.
