I had one, didn't like the way it worked. I ended up plugging the touch hole with a toothpick, pouring the barrel full of water(put a paper towel held on with a spring clamp under the touch hole to catch any drips), letting it set for 15-30 minutes, dumped the black water out, filling one more time to rinse, run some cleaning patches down the bore, dry the barrel, oil and put it up.
