Just purchased new in box still in plastic wrap 12FV from Cabelas this past week....looked good in store, (had small magnalite flashlight to take look into chamber). But upon further examination at home found chamber had quite a bit of oxidation. I am awaiting chamber brush delivery to remove the rust deposit. Is this normal to receive a Savage rifle that may have been on the shelf for quite some time to have some rust in chamber? Also there were no screws in scope mount holes. Gun was shipped to local Cabelas here in PA from another store out west. I have scope on order but won't be delivered for several weeks.
