of them two calibers I would go with the 7 mm
but both will kill all things at decent ranges
However if your heading to BIG bear country down the road, WHY not look into a 300 win mag?
not much difference really in recoil or price for ammo, and just as common place every where! will be able to step up to heavier heads for more dangerous animals if ever wanted to, or just some better performance on larger things like moose and black bears/grizzly's
