Why are Browning guns much more subject to rust than anything else? I just moved into a new house and basement is a bit damp and the dehumidifier died. Took out all my guns to oil and wipe them down. The BSS has several patches of surface rust showing. I know it was oiled just right and handled carefully because it has done this before. So have all the other Brownings I used to own, albeit the last of them went 15 years ago now. Nothing else had a hint of rust anywhere. Is it the type of bluing? I know that anytime I can take a clean gun bore patch, put a drop of oil on it, and if I rub hard on the BSS the patch will turn brown. The gun looks fine, mirror slick dark blue barrels and action, but it just bugs me that they do this. Any ideas?
