RE: home protection
The the ranges you are dealing with inside your home, a turkey load would jerk the spine out of the intruder and deposit it on the nearest wall!
I use an old mosberg 12g with 18" barrell and super full choke with turkey loads myself. If you say that won't penetrate or incapacitate then I say you are smoking something.
I shot a hog with a turkey load at about 30 feet one time in the head and it blew his head open! If it will do that to a hog then it definately will to a soft human!
