What lines are you refering to? Are you saying that you don't have Target Turrets on your Leupold scopes? If you don't you can send the scope back to Leupold's custom shop and they will install them for around $100.00. They have a quick turn around time. The last one I sent them was a VARI X III 3.5x10x50mm. From south MS to OR and back to MS was 14 days. The only differance between the Leupy and NF revolutions is the Leupy's are 15 MOA and the NXS is 10 MOA per revolution. The Leupold will have screw on Turret caps.
You should make a Click sheet also once you get the Turrets. Then you can forget about counting Elevation clicks. Just sight the gun in from 100 yards to your max range recording the Turret's Revolution & MOA setting for every 100 yards. You'll just need to remember that when increasing distance on a Leupy you'll need to go past the setting, then come back down to the setting. The spring in the Leupy tightens on the way down. Not the case on the Nightforce.
