So hitting someone in the face with 6 shot isn’t enough to get their attention?
IF I didn’t get their attention before I pulled the trigger then I want more than their attention when I do.
No. six shot also works wonders on wasps nests up in a tree twenty or thirty feet away that you can’t reach to spray otherwise. The first round takes out the nest and the second for whatever buzzes around shocked afterwards (they hung in a cloud when the nest was gone)
I keep #2 shot in my “house” shotgun. I used to keep lead BB size in it, but can’t find that any more. I suppose the larger sizes of steel shot would be OK, too. At most ranges a shotgun might be used inside the home, even those #6 will be nearly a solid mass.
Shotguns are so impersonal, stand-offish. For close-up personal encounters, some crystal Meth and a 14" machete is nice. If they survive, they will think twice about coming back.
