The 7mm wsm
is probably your best choice of what you mentioned. Without a doubt though, the 300 Winchester is a much more vesatile/all around bullet for everything north america has to offer. A model 70 is practically weighted and also comes in a feather weight edition. Nevertheless the .284, .280, and 7mm
are all good cartriges in the right rifle. Ammoguide has a decent balistics chart with load data.
