Michael that's the best explanation of the mechanics of paper patch I've ever read - far better than some of the books I've tried to decipher. Now I know why I couldn't get my Shiloh Sharps to shoot PP worth anything. (As long as you stood in front of the muzzle, you were safe.)
So, over the life of the barrel, is the paper pretty destructive to the rifling? I can imagine it being very abrasive and taking the gilt edge out of the throat pretty quickly. I was never allowed to cut paper with my grandmother's sewing shears, for instance.
