Some of the ones in my safe never get used so they get oiled once a year. The ones I use get oiled when I am done using them. The ones that I use daily or weekly get oiled every month or two.

I've seen many what would be otherwise perfect and beautiful shotguns look horrible because of an oil soaked/stained stock from coating the action and receiver down with oil and then standing it in the corner of the closet year after year season after season. Over time the oil has run down and saturated the end grain of the stock where it meets the receiver. I know many collectors that will stand guns muzzle down in the safe if they feel the need to oil them. I for one oil very sparingly but will check everything in the safe a couple of times a year if I haven't used some of them in that time frame.

I guess I'm the negligent owner in the group. I never oil my guns unless they get wet and somehow none of them have rust. There are guns that I literally have not shot in 10 years and they have never been oiled, so far no issues.
