OK, first off, I am going to do some more checking so don't anyone go biting my head off and telling me I don't know what I'm talking about yet.
Last time I checked, gun powder was not an explosive, but an incendiary made from sulpher, charcoal and saltpeter. No maybe they add a little acitone for stabilizer but where do we get the nitrocellulose from?
Again, no head biting please. Off to check the ingredients now.
