I don't know what your budget is, but the advice so far has been spot on. I usually consider three types of scope when I need a new one. First, I like the Zeiss Conquest. They are expensive, but worth it. If that's not in the budget, the 4200 series from Bushnell is great, and can be had for a bit less than comparable scopes from Nikon and Leupold. If I am in a budget crunch (which it seems lately I always am) then I go for the 3200 Bushnell. In fact, I have one of those on a Mark V in 270Wby, and that thing is superb. I can keep it inside .5" at 100yds with the rifle's favorite load. Good luck on your search.
