Thread: Barrels ruined by cleaning

Regarding fine rust: I don't think carbon fouling is protective against rust so some sort of oil in the barrel when you go out on a hunt seems a good idea. I mean oil the barrel with whatever your poison (not ammonia or watery stuff like boretech) then dry patch several times and there will be an unremovable film left to protect. My opinions are that Hoppes #9 dries to a bit of a gum so is not so good for storing between hunts, while very low viscosity "penetrating" oils like CRC 5.56 and Kroil go so thin they eventually separate and leave bare metal.

Test your cold bore shot as shown above by @Trout.

I'd be interested in people's thoughts on how to recover from plain fine rust. My inclination would be clean the barrel with oil as you should have, quite a bit of rust will rub off on patches, perhaps some will come out with a phosphor bronze brush and the rest will return to virtually nothing after you "put another shot through to clean it out". I have used butches bore paste specially on the first few inches of the barrel but I think that's more for fire cracking and stubborn carbon fouling. What do you think @ebf ?
