Well we are obviously not going to resolve this here. People will have to look at the evidence and make their own risk assessments. What I wonder is if it is now possible to do any sort of non-destructive testing that was not available 50 or 75 years ago. Any metallurgists or engineers with this expertise out there? That is what we really need: some way to identify the bad ones. Blowing up individual rifles is no doubt fun, and potentially useful for identifying the mechanism of failure, but not ultimately very helpful. I don't know if the bad ones are one in 1,000 or one in 10,000 or one in 100,000, but I have read enough from credible sources to believe that there is some problem with some percentage of the low number rifles. I also believe that the problem is related to the steel and/or heat treating, possibly helped along by the breech design. I guess I'm just not buying mass hysteria as the explanation.
