Bob - I just grabbed a 2.5-10x42 in the MOAR reticle and really like it. Heavy and built like tanks, but extremely repeatable. If you want to have a yardage turret made for it, Gunwerks will do one for you too. That one for $1350 posted above is a great price (I paid $1450 for mine new on sale).
I'm a Swarovski slut but when I feel like spinning turrets on a rifle, I usually go to Nightforce as they are so repeatable and I'm not a fan of the fine Swaro BT duplex reticle - I swap them over to BRH reticles on my Z6's with turrets.
You could also probably get away with that Nightforce high velocity reticle on a 7 mag - kind of a cool holdover reticle.
