I agree with the others that the pressure signs could have been a lot worse. That primer does look flat but there's no cratering into the firing pin hole, no pressure-pierced primer, no extrusion into the extractor groove, the lugs are still there and the base came out easily.
If I now run the touch-lands OAL of 2.143" in QL; assuming the bullet was set back as it slammed into the breech then the pressure climbs to 69.3K lbs (52K is the SAAMI limit). Add to that the pressure spike because it was jammed into the lands and that's a good reason for a case to come apart, but it is not as explosive as it could be.
I agree with the others, once a critical piece has had a an over-proof shock then it's time to replace it.
Yes Sir...a new BCG will be used for sure.
What are your thoughts on the Barrel/barrel extension??
