Contact your outfitter and see what his recommendation is for the terrain and vegetation you'll be hunting in.
As far as mounts go, my rifle's had a Leupold 2-piece base on it for years, with leupold rings. Just about everything I put together today gets a one-piece base. I'd probably do the same with that rifle if I felt the need to update it.
I have hunted for the past 15 years (almost every year) in Alaska...and I have to agree with what homers brother says...I would go with lower magnification...my experience is that your shots will almost all be well under 100 yards (probably under 50) and in dense cover likely...lower power will be much preferred when trying to frame that griz in your scope at close range. My 300 WM that gets used up there had a 3-9x40 Lupy on it when I first took it up there, it now has a 1.5-4.5x40 swift (The Swift's out preform the new Lupy's hands down IMHO, especially $$ wise). I too would also go with a one piece mount on that 338...and would not use Lupy mounts/rings...so many brands out there out preform their rings/bases (I have several sets, and while none have failed me, most are their 1 piece mounts as opposed to the 2 piece sets). Try DNZ one piece ring/bases sets...less moving parts to fail, they get really high marks. I also like Warne, EGW and Millett bases/rings.
Happy hunting...nothing quite like hunting in Alaska...is this your first hunt there?
