I doubt he got the same set of barrels back re-regulated, but maybe. Looks like they are soldered together, maybe brazed. I would imagine they use a laser to line these things up. You only get about 1 out of 3 to shoot regulated, but for a double that costs $900-950, that's not too bad. I wouldn't doubt they reblue and put returns on another rifle knowing there is a substantial group of folks that just want to hang it on the wall. The rifling is very shallow and I continue to have problems loading after the 3rd shot (even with swabbing between shots). Some time ago you suggested that I use a ball smaller than .715 and a patch thicker than .010 and I'm going to try it. Maybe .690 ball and .020 patch. Thanks, PJB
