I don't really like the 7mm mag because it gives up some killing power to the 30'06 due to bullet diameter, but it recoils more. It also is of beltted mag design so it can be tricky to make it headspace off the shoulder for max accuracy. I'm not sure it is bad, but there is just better available. For a do it all on north america with cheap ammo, my vote is 30'06 or 308. If you will reload and want to shoot farther, I'm fast becoming a 300 WSM or 270 WSM fan.

I would also give the 260 Rem a shot if this will be used on just deer and smaller.
