In bad cases it can take a few treatments to get it clean. I have also tried to plug the bore and fill it, but Kroil is so darn thin that is seems to find its way out anyway.

I might have already told you this in other threads, but I had an SVT-40 with a real rough bore a while ago. I had brushed it numerous time with bore cleaner (wearing out several brushes in the process) but it didn't get much better, so I figured it was a goner. I sprayed it with Kroil for protection, and put it away for a few weeks, then I sold it to a friend as a barrel change project. A few days later he send a video clip showing him shooting the "rusted out" rifle, and when I asked him how he cleaned the bore he said "the crud brushed right out and it shoots just fine now"
