Add up all the pros and cons, then make your decision.

In my opinion, within 300yards, the Magnum 7 has no benefits over a .308 - or you could say, what the .308 can do at 300yards, the 7mag can do at 400 - .308 at 400, 7 mag at 500 which is way beyond where 90% of hunters should be shooting.

I mention 300yards as that is a range that is past many hunters ability to make good decisions and accurate shots on game.

7mm mag. ammo that will put up with the inceased speeds costs more, isn't as available, requires longer actions and heavier rifles, kicks more, if harder on the ears - all for a measly 200fps. -

Personally, I see more cons than pros.
