Note: In the image above the elevation turret is in the unlocked position. The windage adjustment is housed under a removable cap. This was a fairly simple and straight forward process. The turret then gets unlocked and moved to zero, then the turret gets locked again and the set screws tightened.
Zeroing the rifle and setting the zero stop requires the scope to be adjusted to the point of impact with the turret locked and the set screws backed out slightly.
