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.
