rifle detonation again

[Nuclearcricket]

Well everyone has made good points, and yes I do agree that jumping to conclusions isn't a good thing. I have seen some posts on other sites and it does bring up some questions. Everything I have read says that the barrel split both top and bottom. I have not seen any mention of the action letting go. This makes me wonder if perhaps the barrel was bad or perhaps had a flaw in it from the get go. Having worked many years as a toolmaker making parts for use in injection molding presses as well as progressive stamping dies I have seen tool steel with bad spots in it and inclusions in the steel. This has been in air hardening tool steels and I am not positive how they are made but I would guess that they are hot rolled or hot formed at some point.
I do know a fellow that has on porpus blown up a 74 sharps. He built the rifle and had done a Gove conversion on it so that the block will cam a cartridge into the chamber. He would not tell me what kind of load he used to cause the failure but I do know he was unhurt. It was a 45-70 and it would be my guess that it was a load I wouldn't want to put in my Mauser, or at a minimum not a load I would be willing to pull the trigger on.
I do hope, and I think we all do, that the person that was injured sustains little to no permanent damage to his hand and that he has a speedy recovery.
