Anything a 7 Mag can do, a 30-06 can do as well or better.
I've never liked the 7 Mags, so my vote is '06, of which I currently have 3 (one in Denver). And a 7X57.
The only place a 7 Mag might have an edge, begins about 400 yards out, IMO. But I'll put up my 27" heavy barreled '06 against a 7Mag even then, for accuracy, to the range I'm willing to shoot -500 yards.
The rifle is a 1,000 yarder, easily, but I'm not.
