[DL] volitility

[Doplegnger@aol.com]

OK, one other quick question if somebody with a little more knowledge on the 
subject would be so helpful as to answer:

just how volatile are shotgun shells/bullets (mostly shotgun shells)

obviously throwing a backpack full of shotgun shells into a blast furnace is 
going to be one serious shrapnel bomb, but just how much is neccessary to set 
them off? muzzle flare enough?what about a lighter dropped onto a stack of 
them? just a lot of heat (throw a backpack full of shotgun shells into the 
steam from a ghost rock furnace and create an air detonating massive shrapnel 
bomb)?    I have never seen shotgun shells personally so I'm not really sure 
how much you need to light them all off.

thanks!
