Thanks guys, sounds like mythbusters indeed.

They would probably start by directly shocking a round all by itself and seeing what the threshold is, then going from there.

Circuits, I don't know anything about igniting powder or primers (obviously ), so most of my questions are going to sound stupid.
-Can you ignite gun powder from a direct electrical shock in the first place? If so, is it not a function of electricity at all, but just the heat created?
-What is the difference between the primer and the lose powder in the round, in reference to the topic of course?
