A week in the inclement weather on an extended hunt without oil won't phase a stainless barrel, just clean it when you get it. Do that with a blued barrel, you'd better pack some oil with you or you'll be cleaning off some amount of rust.

If you go into the profiles of the immature posters there is an "ignore" function so you don't have to put up with them. If people didn't reply with quotes in this thread I wouldn't even see them.
