Doug Turnbull said the right barrel was measured three times. Thing is - I put over 100 rounds of RST Lite 1 oz. at 6800 PSI through that barrel after I bought it at G&H before I sent it to Doug for inspection and cleaning. Doug's shop provided the surprising thickness measurements. I requested measurements from G&H when they removed the pits I noticed. I was told they didn't have the barrel measurements handy but I was assured it was safe to use with low pressure RST ammo. I sent a note to their gunsmith regarding the thickness issue and haven't heard back.
I researched the Teague option and read one bad review about "bubbles" showing after the process was completed. There was some discussion that the barrel(s) walls may have been drilled out completely in one area and the lining adhesive was visible. I spoke with Gary at Briley and will probably have it sleeved by them. Cost for one barrel is 1300.00 and for both it's around 1730.00.
