If he was to do that, might be better to start with more like 1000 or even 1500, I found some at Home depot over in the paint section. How to do, stick a circle onto the end of the dowel w/ dbl-sided tape (ejector and extractor removed) and swish it by hand against the face? be sure to rinse out any grit afterwards...
Yeah, I'd be worried about doing that to the bolt too. The barrel is just a heavy stainless steel barrel so I wouldn't worry about hardness layers in the chamber, but the bolt should be case hardened and increasing its headspace could take away the hardness.
