I find a simple way is to shoot at 55yds and make any adjustments adding or subtracting
clicks then reset my turret to the normal number.
So if 55yds is normaly 40 clicks and I have to add 5 clicks to maintain poi at 55 I leave the scope set at
45 clicks undo the top turret and set it at 40. All ranges then should be with in a pellet whith
hope this makes sence
