Well, I haven't gotten to that point yet. I have a set of cleaning tools for the rest of my guns, all I have done is "modify" (cut the extra core wire and solder it closed) one of the wire brushes. I've tried putting patch on the end of the brush, running it to the back, pushing it so hard it almost bends the wire, and twisting. I think my next move is talking to a dental hygienist friend and getting a cleaning pick then going through the touch hole.
