Yeah, a .338 could sure work as a back-up to either the 7mm or .375, depending on the hunt.
Blued and walnut can work pretty well for use in nasty weather with some spar varnish on the stock (whether checkering or inletting) and Dyna-Tek coatings on the metal, whether Bore Coat inside the bore or Gin Shield outside.
Gin shield sounds like just the thing for after a cold weather hunt.
