We are using a long rifle in BATB for Gaston shooting the bird out of the sky. The sound will be produced by one of the methods in the Gun Shot thread. It would be good if I could get a puff of smoke from the barrel. I expect that Gaston will be offstage, but the barrel could poke out into view. The gun is a good-looking toy; I think it was made for caps. Maybe some fine powder in the barrel and a tube for the actor to blow into? What has worked for you?
