I would shoot a 175 Partition in the 7 Mag and the difference between that and the 280AI with the heavy bullet is pretty much zero in the real world. 7 Mag is easier to find ammo for in general but that is the only real advantage. If you could load a regular 280 hot it would make me feel better but that would depend on the gun. You might wind up 2500-2600fps with that and that's getting slow for my taste but certainly would kill something. The issue is you don't know where the accuracy will be until you shoot a whole bunch. It can be done. It's just easier to start out with something that already has the desired amount of horsepower. There is no replacement for displacement. Elmer Keith said it best "I like one-shot kills where possible and prefer to do all my hunting before I shoot."

No government employees were harmed in the making of this mess.
