Is that possible in the middle of a skeet run? I flagged this one up because felt there were unresolved inconsistancies which I still feel are unresolved.
I have seen a few shotguns that have let go and quite a few more after the event. I still feel that this is sufficiently ammo related to come within the remit of the forum because its clearly something that ammo buffs might consider to be part of the bigger picture.
The fact is, they don’t go like this. If its a mystery, then so be it, but nobody should get the impression that this is a normal blow up .
Shotguns are very safe because of their low pressures and the huge drainpipe of a barrel always provides a safe exit for overloads even if if it may bulge things a bit on the way out.
I think this post has run its course, the subject will have to be consigned to the strange but true file and we will never know.
