Condensation inside gun case - maintenance question

[MG5150]

Hi Everyone

Last night I went out for a fox hunt and got a few drops of rain earlier in the night. It cleared up for the last 2 hours and I put the gun in the case dry.

When I got it out this afternoon, the barrel and other exposed metal had condensation on it including some of the bolt.

I dried all the metal, ran a patch through it a few times, then a second patch with some gun oil and wiped down all the metal with an oily patch.

Lesson for next time, don't leave it in the car overnight (even if I get in at 2am) - Do you think I have anything to worry about in terms of rust inside the barrel?

It's a Lithgow 223 Varmint rifle with some sort of blue/black ceracote on the metal.

No, the bore should be fine after dry patches then oiled patch. If I got rained on during a hunt I would spray the F out of my rifle with a dispersant such as 5,56 or WD40 then wipe off where I could, then pull the barrel out of the stock and clean all the metal and wipe the stock within a day or two. Never had a rust problem.

Should be fine but you do have to be wary of rifle bags.

I have never had a rifle rust in my safe, or when out hunting in the rain.

I did have spots of surface rust appear on my stainless Tikka hunting rifle after a 2-day, 1-night trip.
The gun bag had a bad wet patch as it must have been right under where the ute's hardtop leaks the worst.

Keep an eye on those Lithgows. As I understand it, they use carbon steel for all their metalwork and cerakote the exterior. The bore will be exposed to moisture, especially any residues that could suck up the humidity/moisture of the conditions of your storage.

As has been said, use a water dispersant on any exposed steelwork.

Do you spray WD40 down the barrel and inside the chamber?

[Wapiti]

As good as WD40 is at lifting moisture off the surfaces, I wouldn't spray it around the chamber and bore. They are tye most essential areas of a firearm to preventfrom rust. Patch the bore out mate as you would when putting it away, with a firearm bore corrosion preventative.
Hunters away from home will bring along a little kit for this, as much as it is a pain to do so when in the field.
Ensure you dry-patch it out before starting hunting again.
