You really aren't a fan of shot guns are you Cliff.
I love shotguns.....for wing shooting, waterfowl, and turkeys.
They are probably the best choice for a home protection gun and very historically accurate for use in our classes although I don't feel shooting both a shotgun and rifle is very historically accurate, still that is not my main reason for not shooting one.
I don't think I'm alone in not being turned on by shooting stationary steel targets from a few feet away with a shotgun. Probably for the same reason a shotgun makes a good home defense gun, its kind of hard to miss unless you are playing some kind of crazy speed game. In other words I see no challenge in shooting the shotgun at steel plates other than speed which just doesn't do anything for me.
