JIM, get yourself a bottle of root killer crystals and a stainless-steel TiG welding filler rod. Grab some tiny O-rings and tapered rubber plugs from the hardware store and your old 6/12V trickle charger from under the bench in the garage. Degrease the barrel with brake cleaner followed by streaming-hot soapy water. Plug the breech with a rubber plug. Mix a strong solution of the copper sulphate pentahydrate with distilled water, melted snow, or rainwater and fill the bore 2/3 full with it. Put o-rings on the rod to keep it from grounding out to the barrel, poke it in the barrel slowly until it stops on the plug, top off the solution (an eye dropper helps with this), and look on tje internet to figure out which way to hook up the charger because I can't remember right now. You can use an old wall charger fir a defunct device that outs out 12vDC and something like 200mA, but it takes a little longer to work.
This will plate the copper onto the rod. You will have to empty the works and clean the barrel every so often as you uncover layers of grime which big down the reverse-electroplating process. You will also have to clean the copper off off the rod at the same time.
