I've successfully hunted moose with stainless/synthetic rifles, and with wood/blued. It really has depended on what I've felt like walking out the door with that season. There really is no question about either cartridge...much less would do. However, there is a good argument to take your .375 H&H, since as others have pointed out, moose is one animal where you can use the excuse of taking something larger.
If I walk out the door with wood/blued, I simply stash some ziplocks with oil soaked rags in a few places, and take the extra time on a daily basis to wipe my rifle down. If you do take your .375, I highly recommend bringing the tools to take the rifle apart after your hunt, and before your fly home....a couple days in a rifle case can wreak havoc on the internals of a wood/blued rifle. That includes taking apart the bolt and wiping it down.
