Hi guys, From time to time there were discussions here about burning/flammable/incendiary ammo. While there clearly are safety issues to observe, shooting something flammable does sound cool. But, safety first, in the form of the MythBusters mantra: Don't do this at home. With that out of the way, in a recent thread the discussion touched upon ferrocerium as ammo that ignites on impact. I just stumbled upon this video where lighter flints (which consist of said alloy) are used as shotgun ammo. The results are quite promising.
