I have wondered before why folks believe that chamber sleeving to a smaller ga. would convert an unsafe barrel to a safe one. Say your 12 ga. barrels are damascus and too badly pitted or dented to be safe to shoot. I can understand that full length 16 ga. inserts might make things ok, but why would chamber inserts or sleeves make the bad barrels suddenly safe. The pitts and dents would still be there, and I doubt that the pressure reduction of switching from 12 to 16 in the same bad barrels would be enough to cure the problem...Geo
It would not make unsafe barrels safe. It would make compromised chambers and or forcing cones safe, which is the original purpose of chamber sleeving.
My intent is to convert a lightweight set of 12ga barrels that are spare to allow me to make a Churchill16 SxS
