....When a gun maker is 500 years old, and has been a leader in advanced manfacturing techniques for milions of firearms, people are looking at the wrong end of the horse for the "why".
Thank you CZ for the explanation of the part I snipped out. I personally prefered it to the previous.
There seems to be some conclusion that impurities in the metal, steel in this case, caused the failure. Some of those double vacuum melted steel alloys are incredible things, but more often than not, they seem to be high carbon hardenable steels. I don't know if it makes much sense to imply that regular fools settle for good enough.
Only for curiosity, if a ring bulge shows up, it's possible that the manufacturer was unlucky enough to release a barrel tube that had near perfectly distributed circumferential inclusion defects? I'm not thinking that could be concluded, just that maybe it's a viable scenario? Maybe the maker is at fault? Wouldn't a blow up violate the owners manual and stamped warnings about safe operation? Small as it may be, I think there's some learning to be had.
