It was wet and sat around for days, nice. I am looking forward to seeing Drews high resolution ultra-close up images just out of curiosity. Perhaps it was a one off and the shooter just 1) placed bomb in chamber 2) pulled trigger and 3) spent quality time with physician. If not high pressure alone any ideas as to what a possible obstruction might have been? Are there any other tidbits of information missing from this incident report? There are bright fractured surfaces as well as stained. Were other pieces broken away days later?

Anyway, after looking at the pictures again the shooter was quite lucky, things could have been much worse.
