BD this was really just a down and dirty starting point to satisfy my own warped curiosity. Most of your above factors were considered and I also thought of using multiple chokes and additional loads. I kinda just wanted a practical idea of what might happen inside the constraints of a home if my aim was off. Some here seem to scoff at the idea of using a scatter gun for home defense as they think it lacks power needed to incapacitate unwelcome guest.
Your descriptions of how individual guns of the same gauge perform differently is well taken. I have two almost identical 20 gauge A5 humpbacks both with modified barrels. One I use for birds and it is patterned about as open as a skeet choke. The other I generally use for doves and rabbits because it is much tighter. Who knew shotguns and women are so similar?
