I just ordered a Savage 10 Predator Max 1 in 6.5 Creedmoor. I also have a Leupold VX-3 Long Range 4.5-14x40 30mm with CDS. I got the scope in a trade so I figured it will go good with the 6.5 CM. For right now I am going to start practicing at 500 yards but I plan on stretching her legs out to 800 if the gun can handle it. Leupold states that the scope has 116 MOA of adjustment. MidwayUSA says 113. So I guess my question is should I buy the 20 MOA base now or wait? I want to get good at 500 before I take her farther out and I know I don't need a 20 MOA base for that. Going by my ballistic app using a 140gr A-Max that is zeroed at 200 yards, I will need 63 clicks for 800 yards. Using the 120gr A-Max zeroed at 200, I will need 57 clicks for 800 yards. That will be maxing out my scope. Thanks for any help.
