    Correct Patrick. I was just stating the obvious. The link Littlelebowski posted took you to a bunch of BR barrel makers and competitiors and they were chiming in with their recommended cleaning regimen. My point was, even if occasional use of an abrasive is used to clean copper, even if the abrasive results in a slight wear on the barrel, our crowd can tolerate a slight accuracy degradation from any supposed wear whereas a BR shooter cannot. Once their barrels start grouping in the .3s routinely, it's shot. We'd rejoice at that level, and if our 1.4 MOA shooter degraded to a 1.7 MOA shooter, we wouldn't sweat it.

    That's my point. Why permanently degrade accuracy when the effects of copper fouling are the same in the end as using abrasives? Instead, just soak the darned thing with solvents. After very hard use, when accuracy falls off (which would take thousands of rounds most likely) is when I'd run a nylon brush with Iosso paste on it down the barrel. Iosso is one of the least abrasive of the abrasives if that makes sense

    Montana Copper Killer works for me. Get the bore wet with that, run a patch wet with hydrogen peroxide through it and you have a potent foaming bore cleaner.
