Ah wait - I do see it now. The head shows extrusion into the ejector and extractor areas. That's definately not headspace nor OOB, as both of those would relieve the pressure before enough pressure builds to flow the brass like that. THat's a massive overpressure, not a case failure. So now we're looking at overcharge or obstruction of some sort, or combination of those items. Definatelly please confirm what your cleaning and inspection practices were with the new barrel.

Also, double bonus points on the bolt holding up to that. That went just a wee bit over the 52,000 PSI rating.
