IMHO I wouldn't think that there is enough of an increase in "power" over the 30-06 with the 300 wsm to justify buying a new gun (but justification is rarely an issue). I would move up to the 338 win range of guns. A 338win, 325 wsm, 300 ultra, 8mm Rem etc. My suggestion of manufacture would be a Winchester Model 70 withcontrolled round feeding or the ole stand by Rem. Model 700. As far as glass goes I would buy a Leupold VX III in 2.5 -8 power.

With the kind of money you are willing to spend you could buy a custom built gun with a really nice walnut stock andmatch grade barrel. Something built on a Rem 700 action should run you in the $2000U.S. range, of course that doesn't include a scope. If I where going to build a "hunting" gun I would use a stainless Mod. 70 controlled round feeding action. Barrel itwith a shillen or douglas in 338 win. I would cut the barrel off at around 21" and stock it in a HS Precision stock. It would give me a reasonable weighted, easy handling, weather resistant, hard punching mountain rifle. Top it off with some Leupold glass and watch out big game cuz here I come.
