A 'massive explosion' will destroy anything ina 50' radius. Sorry, but I am a bit peculiar about such hyperbole. (And I have a thing about explosives... bad combination )
okay it wasn't that big but it was definetly louder than my 3-5 gram petn compound detonators, one of the detonators would probably have put me in the hospital due to copper schrapnel.
it was a rolling boom/thunder, you know first you hear the massive boom the a few seconds later you hear the rolling crackle of an echo in the distance. I am not sure how loud somthing has to be to do that but I know it has to be louder than my 3,5,and 8 fram flash charges so it was pretty damn loud. my parents said it shook the entire house.
and I doubt the air would be able to push out a stuck wax slug, it was cast into a three inch peice of my barrel(2 inch sch 40)
