I'm baffled by this thread. What could possibly be the point of firing a shotgun shell from a flare gun or a flare from a shotgun? I mean, I do realize that a lot of things are just asked out of mere curiosity (what would happen IF...) since we shooters are a naturally creative and curious group, so I'm not trying to sound like too much of a jerk but PLEASE....whatever you do DON'T even THINK about trying this!!! I guarantee, your shotgun will do a much better job of shooting out shotgun shells than anything else, because that's what it was designed for in the first place.
