The guy who sold me the Havoc and I were talking about using small fire crackers to reload his plastic shells from his bird bangers. It seems doable enough with a bag of tubes and caps, but then he mentioned 1.25" artillery shells and it made me wonder.

I can see right now my best idea yet is to use this as trade fodder, especially since I have actually said "hey y'all, watch this"!

Edit- I know I can gut a roman candle and make a shell out of that, but I'm wondering if there is any way to do it even easier.
