To compare one of each with about the same amount of case capacity there isn't much difference. To make it easy, compare the 280 Rem to the 30-06. Both are great rounds but the 30-06 won't do much more than the 280 would do. I wouldn't necessarily compare a 7mm Rem Mag to a 300 Win Mag as I believe the 300 Win has a little more case capacity but maybe a 7 WSM to a 300 WSM would be more fair. Which ever you would choose the cut off for hunting IMO would be just short of the great bears. I think most would agree that more bullet than either can offer would be better suited for that task.
