Rifleman. If you can cite me one documented case of a flask going off when loading a revolver where a burning ember in the chamber ignited the powder being poured in, I'll take it under advisement. Every thread that I have read on every forum that I monitor has never cited first person experience. To date, all the naysayers have only referenced third person anecdotes - my cousins neighbors stepson heard about one that went off at a range - or that some other unsafe activity, like pouring powder while smoking, or using combustible cartridges and not checking for embers - or that the event was in actuality from a long gun or single shot pistol. Those events prove nothing in regards to revolvers. BTW, I've been an NRA member for over 30 years and a NMLRA member for 20. Do not recall a revolver blowup article in that time.
