I'm sure we've all got one or two long guns that we only shoot once in a blue moon (read: less than once a year). How do you store them? I've read a lot of people saying to use heavy grease or cosmoline, but it seems somewhat unnecessary for modern designs.
For context, I've got what I consider an investment-grade AK build. I take exceptionally good care of it to the point of trying to only ever handle it with nitrile gloves on to avoid oil transfer or scratching of the wood. Exposed metal is hit with Barricade and/or CLP, moving parts and rails were given a coating of CLP or TW-25B grease. I haven't shot it since I got it a year ago, and I'm not sure when or if I will. I got to thinking about whether or not I need to give it another rust-preventative light oil coating last night, but now that I think about it, it really shouldn't need it, should it? The barrel is chrome-lined, the bolt and BCG still have the original paint that kept it rust-free for the 34 years it sat around in a completed gun and as a parts kit, and the receiver has Barricade or TW-25B on any bare metal, with the rest covered in a modern moly-resin finish.
Every other long gun I have usually gets a relube or is used and cleaned at least once a year. I feel like I may be overthinking this, but I'm curious to know how other people store and maintain their non-use rifles.
