I PM'd Paul but will chime in here on this thread too. From what I know, the vast majority of guns that went through the process were successful with no problems what so ever. While I was the representative we did have one failure after proof where the outer barrel had a thin spot and actually became de-laminted from the liner. I refunded the client's money on that particular job. When I inquired as to how often these type of issues had arisen in the past, I was told only a couple of times in more than one thousand sets of barrels. How true that is I can not say.
