I doubt the bore has a nickle finish. Clean the bore with Hoppe's anduse a little oil on the surface. By the way, the #9 is a powder solvent. It won't remove the copper fouling from shooting. You'll need something different, like Butch's, to do that.
I'd like to meet the man who at some point, somewhere, somehow,didn't accidentally get any bore cleaner on the exterior finish ofhis firearm. We've all done it, be it a small drop or a big sloppy mess.Schoolcraft is probably thinking along those lines......
