I've been advised that an oiled bolt (left in) prevents oxygen from traveling into at least one end, the other should be resting muzzle end down in an oily rag. Ive done this since day one and never seen corrosion yet. If thieves can get into my safe - that means they have the tools. That means they'll be into both sections of the safe withing minutes of each other. Waste of time - and it raises the risk of me leaving the bolt at home.
