Not all blueing is created equal. Gawdy as it may be, I'd expect a lot better rust resistance from the high-polish bluing on a Weatherby MK V, Browning A-Bolt Medallion, Win (USRAC) XTR's, etc. than I would from a 700 SPS.
Circa late-90's a buddy took his Kimber of Oregon 89 to Alaska on a caribou hunt. It was orange by the 2nd morning. He bought several SS/Syn rifles upon his return from AK.
I hunted caribou on the N Slope of the Brooks in '11. There was more danger of the rifles rusting in the hard-case on the plane flights than there was while we were hunting. We all had SS rifles, but, I'm pretty sure we could've easily completed the hunt with bbl'd actions of carbon steel "in the white" sans any rust.
I’m a big fan of stainless in conjunction with Eezox or Corrosion-X. Stainless and Cerakote is maybe the best option.
If it is blued, I believe the deep gloss bluing is best. The Remington SPS is simply Horrible!
