The guy I do my Hunters Ed tell the class about the clickity clack of the pump and if that doesn't work let go of the 00 and slugs. As I'm rolling my fukin eyes. Firearms and ammo are tools that work better for a specific application. For up close bird shot to the face will slow things down, 3 to start then 00. Just like pistol ammo, drywall and some masonary will not provide cover in an Urban setting. Neighbor will not appreciate getting dead or shot up. The proximity to the good guys needs to be considered. Don't be that guy.
