Over the many years of hunting with muzzleloaders, misfires and no fires have kind of taught me to not be lazy. I used to not shoot them off because.. well I just did not want to have to clean the rifle. That to me is lazy. After my experiences... I can say with pride I am not lazy. And I don't take chances. When I come out of the woods, the load goes out. Either shooting, in the case of a traditional. Or in the inlines cases, I push the load out. I wipe out or clean the rifle what ever might be the case. And load fresh in the morning.

I know the sound you heard. Just not a full blow BOOM!! And you're lucky you did not wound that doe. I do hope you score some venison again.
