Good notes Stu, few really realize how dangerous guns were back 'in the old days' often more so to the guy using it. Naturally flintlocks could easily blow up if too excessive charge of powder. We never hear about those cases in accounts of battles.
I once visited a museum in Wyoming that featured lots of guns dug up in old battle sites etc. There were some revolvers of the Colt navy type (hard to tell as they were in bad shape) but had exploded when firing literally in the face of the guy shooting, it was noted he did not survive.
Good to have some humor here and not always so serious !
