As for hitting anything with the shotgun, it looks like I am finally averaging a 20 but still not straight 25. If I had to I think I could hit center mass at 15 feet.
There ya go - just shot my State's Sporting Clays Championship - won some money and enough punches to move up to another class. I am 4/5 when it comes to registered shoots and winning my class, so you damn right someone comes near my clay guns, that would be like coming near one of my kids!
The best defense is a good offense - harden the home, prevent the break in from the first place, get a good dog, thorny bushes, etc., but if they still want to break in and possibly cause harm, take no prisoners - never shoot to wound - THAT will get you jail and sued faster than killing them
