I had a plastic hose rig I used on a Kentucky and one I used on a under hammer; I made them all they were was a old nipple that was burned out drilled out so the hole where the on the end where the cap goes was that size all the way through then I mounted the clear plastic hose on it with silicon adhesive. They were not real fast but they worked quite well. To use them I took the shooting nipple out and put the modified one in and poured boiling water through a funnel into the barrel it drained down through the modified nipple into a can the I worked the barrel with a ramrod with a jag and an air tight patch so it would suck the water back out of the can and into the barrel then push it back out again.
