A Hawkeye does help in that regard. Clean patches don't always tell the whole story.

^^^^^^^ THIS.^^^^^^ I have to agree fully with that.
Prior to getting my borescope, I had the bright idea that since I had a few new unfired factory rifles that I had thoroughly cleaned with a phosphor bronze brush and Shooters Choice, that I could simply go ahead, degrease and dyna bore coat.
After all, I thoroughly cleaned them till the patches came out white, right?

Sure glad I waited till I got my bore scope, it would have been a disaster, I'm sure.
Here are a Remington 700 and a Ruger 77, new from factory and unfired that I would have sworn were spotless till I stuck the borescope down the tube.

And same 2 barrels after a proper cleaning with JB Bore Paste & Kroil on a patched phosphor bronze bore brush prior to dyna bore coating. Quite a difference in what I thought were clean barrels.
