The Greg Ferris stories have multiple shots fired. Ayoob has written it up. Two robberies at a gun store where Ferris used several guns in the course of the fights, IIRC.
http://proarmspodcast.com/107-ferris...rms-robberies/ - This is one of the incidents.
I'd note for the shotgun fans.
1. You can miss close up with a shotgun.
2. The pellets can go across the street
3. There was a civil suit threat even in this clearly self-defense incident.
4. The shotgun was effective.
5. Under stress, Greg forgets his sights on the first shot.
Second incident
1. Bad guy screws up a shotgun and missed close up.
2. Greg fires 7 shots from a 38 Super
3. Assistant joins fight with shotgun multiple shots
