I do not have the converson,I was planning on getting it and the guys on some forums I check out now and then were complaining about them so I backed off. Then this fellow was shooting out at cleborne county range when I stopped by with a friend, he said he had misfires while hunting deer with that conversion. He showed me what he was using ; he had bored a breach plug to fit some heavy brass tube,cut the front thin so it would seal like a shell the back end to fit a large rifle primer. He was using Pinnacle and the bullet Hornadymakes like a shock wave only with a red plastic tip; he shot for 2 hours he cleaned his encore twice he never touched the breach area and it looked as clean as a cartridge gun his targets had mostly interlocking holes at 100yd {of course he was shooting off a bench rest. So now I am wondering if there is some thing available or if I might end up buying a small metal lathe. Lee
