What I thought was rust, and fought like crazy for 3 or 4 days is not. after soaking and patching, and lapping, and scrubbing with everything but grape jelly, I can clearly see that what I thought was surface rust on the barrel, are actually voids in the metal. I wondered why all my cleaning wasn't knocking this stuff off the bbl, now I know. What started all this was me reading about the outers foaming bore cleaner, and decided to try some. Man, I always clean thoroughly, I thought. This stuff pulled so much purple goop out of my barrel I thought it was a scam, and just turned purple on its own, but NO, after about 3 soaks of about 2 hrs. each, the foam was finally stayed white. That is when I saw the "rust". 400 words later, my question: should I start back with a basic break-in routine since I am now down to a clearly gravel road bore? I had another post about Penephite Kroil, a lot of benchrest dudes use it after cleaning, for cold shot consistency, and to reduce fouling. It's basically purposely carbon fouling your bore, with superfine graphite. Anyone know about that? Those guys do alot of voodoo and I don't want to be a hoodoo.
