Both shoot plenty flat for ranges one should be shooting at game so its still a toss-up I prefer the 30-06, the next guy may prefer the 7MM. Take your pick.
The only thing that I can add, is that I was able to take an elk with my 30-06 at a measured 304 yards, but I believe that I was about at the limit of that caliber's "flat" shooting capabilities in my rifle, with my hand loads. If the bull had been at 375, I would've hesitated to use the 30-06, given the MV for which the cartridge could be loaded and the "holdover" that would've had to be used. With a hot loaded 7mmRemMag, that range could be stretched another 100 yards with little concern for bullet drop. The choice is yours, but for longer ranges on deer sized animals, I would opt for the 7mmRemMag or one of the other 7mmMag cartridges.
