FC, MB, WA, and saddlesore are giving you good advice, IMO.
I have used the 30-06 for much of my hunting here in Alaska- mostly with 180 gr c&c bullets. Never found it lacking.
Well, I did buy a .338WM some decades ago, more for mental comfort than any real need. Those 1-2 gallon piles of steaming bear poop I was coming on in heavy cover kinda put the spook on me for a time. Never needed it for that, tho it does as well as the '06 on moose, and not any better as far as I can see. I have gone back largely to the '06 or .260. Haven't even fired the .338 in over a decade, and I like that gun!
