This had me chuckling a great deal in my little workshop. And this happened by mere chance. I totally forgot to deburr the inside of the rear ramrod pipe. So when I was just fitting my ramrod it acted as an AWESOME scraper. When I got the ramrod down there to the rear pipe and inserted it, it proceeded to shave some off. I said to myself, "Lets go with it" It worked fantastic. I then removed the ramrod finish sanding it and took the needle file to the inside of the pipe to deburr it.
