A lot of wisdom in sticking with what works for you -- stay with Leupold. In fact, staying with the same scope -- VariX III 3.5-10x 40 mm -- makes a lot of sense, too. In a pinch, you could likely quickly cannibalize one scope off another rifle and move it to the other, for example in the instance of a remote hunt (provided you carried the second rifle with the same scope as backup).

For a hunting rifle -- unless your hunting requirements are very definitely specialized -- I would avoid an oversized objective lens scope. Similarly, I would avoid an overly powerful magnification range.

Other opinions may vary. Good luck and happy hunting with your 7 mm magnum.
