Thread: What to do with .22 BRNO barrel?

Bit of an update for those that are interested- I took the advice above and gave the corroded area a scrub with a copper brush and some autosol, then a few patches pulled through. Barrel came up bright and shiny, no residual corrosion which was very positive; I was concerned about pitting. The rifle now shoots accurately again and I'm absolutely rapt. Thanks very much for the good advice, think I'll be more diligent about cleaning the barrel in future. Cheers
