Drew,
The test results that you have provided high-light the fact that the person that discharged the gun prior to the barrel failure was negligent; in that he/she failed recognise the potential risks involved when ever a weak/blooper discharge is experienced.
it should be standard practice for all participants in shooting sports, that when ever a weak discharge/blooper occurs the shooter must check to ensure that that the barrel is clear of obstructions prior to reloading and firing another shot."
The test results indicate that in the failure under review that this safety precaution was not followed.
Collectively we need to stress the importance of following the safety check described above in particular with every new entrant to shooting sports and for that matter some experienced sportsmen.
