[QUOTE="Lenny Foffa, post: 2189605, member: 100742"] The injured shooter said in a conversation with the Rifle manufacture , that he was told it would take 85,000 pounds to cause this catastrophic failure to occur. I would have thought the company would have proofed this rifle to that level of pressure. There should always be [B]"Destructive testing to Failure " for any production rifle, [/B] just as we did with our medical Trauma Implants. We knew How much load, and how many cycles before the Intramedullary Femoral Nail , or other device ,would deform or break. On another LR thread , they are talking about the new 277 Fury ( if I read it correctly ) approaching 80, 000 pound of chamber pressure .
