Use some CLR same stuff you would For lime and calcium buildup on faucets and showerheads. Put it on a page run it in and let it soak and then scrub the hell out of it coming back with the Boretec carbon and then eliminator in the barrel. The CLR will help Break up with carbon ring.What are the best copper and powder cleaners? I picked up a Used 270wsm and the accuracy wasn’t up to snuff. I suspected a fouled bore, well I’m on day number 4 of scrubbing and soaking with butch’s bore shine and M-pro7. Even letting it soak over night and thru the day while I’m at work! No end in sight. I was starting to wonder if the barrel was cast iron and coming off on my patches. I have finally gotten down to blue patches so I know I’m getting copper now? Any suggestions?
