I have had great results from JES. I had a bad barrel on a martini cadet someone screwed up befor JES got a hold of it .. When I discovered the problem and was sure it was not his fault I found another barrel (luckily) and sent the gun to him with a check for the new work. He did the new barrel in .357 maximum as I wanted and the chambered the barrel with the bad chamber in 35 herrett for no charge. An honest, fast turnaround craftsman
