Hell, nothing new here, when we were kids, 55 years ago, we used to stick shotgun shells into hay bales and shoot the primers with a 22 from 25 yards. Also lit matches as part of the game. The empty shotgun shell would launch itself 15-20 yards in the direction of the shooter. Primers were destroyed by the 22 round so never saw primers flying about but I could see it happening with a BB gun. It never ceases to amaze me the number of dumbazz things we got away with as kids. Good thing there was no Youtube to post our dumb stunts on.
