I'm going to say this as politely as possible, but please don't do that.
I ran a Leupold scope with the CDS system for a long time. The issue was I never hunted EXACTLY in the conditions and climate and elevations my turret was cut for, not even once. So my turret was always ***slightly*** off.
If you're going to really do the long range hunting game justice, get a good solid repeatable scope, a good ballistic app, and a good rangefinder. Then go practice A LOT. Get good dope, and then run the ballistics on your phone just prior to the hunt using the conditions and elevations you will expect and build a chart specifically for that hunt. Then do the same thing for the next hunt, and the next one, and the next one. You'll be better off in the long run and you'll be a better shooter because of it.
My suggestion is to pick up a good, solid scope from a company that has a good reputation for toughness and reliability, like Nightforce or Trijicon.
But hey, I'm just some random guy on the internet...
