On the subject of rust bluing, I just got a set of barrels back from a gunsmith, and one of the chambers is covered in a rough residue, While the other is polished smooth as it should be. Perhaps one of our resident gunsmiths could comment on what that residue is likely to be and how someone like myself might be able to remove it.

And I checked as soon as I read the post about the barrel flats. He left mine blued.

Only cleaned one chamber/barrel? If nothing else I would call him and let him know.
Steel wool on a cleaning rod, with a little oil, spun with a variable speed drill, slowly will likely do the trick, but won't be as bright as the one properly cleaned. The entire barrel likely needs the cleaning. This is normal for rust bluing, even if you plug bores, which I do.

Or a Frontier pad.

This?

Looks good. Ordered one. Thanks.

Yes, that's it. It will not harm bluing, case color (except that stained color on Repros) and it will not harm composite barrel finish (but will harm the finish put over refinished composite barrels).

Edgar says you can use stainless steel scrub pads made for pots and pans... I've never tried that, but he says it's the same stuff...

I have found that once again Edgar is correct. Same material, same result.

Well, not entirely the same. They are $2.98 for a 3 pack from Amazon, and $6.00 each from Big 45, but I think they were even higher than that a while back.

Edgar have you considered a job as an editor?

NOW you tell me. :banghead:

No, other than to occasionally pick on Dean, the only other periodical I ever studied in depth was Playboy.
