I would of course defer to someone with barrel in hand, but do not definitely see a ring bulge. The top rib extension is gone but possibly just from the burst. The destruction of the FE and broken stock suggest MUCH more recoil than one would expect from a properly loaded factory round ie. almost something like this Citori



A formal Metallurgical Failure Analysis would be most interesting
