20 guage with #4 buck works really well. Unfortunately, around my house, they seem to come around about 2 o'clock in the morning. They drive the dogs crazy and they wake me up. I grab a flashlight and the shotgun and run outside to attend to business. It's only when you come back inside that you realize that you were running around in the dark, with a firearm and a flashlight in your "fruit of the looms". If I'd done something like that in Dallas, I would have been surrounded by squad cars of cops in about 5 minutes. Lord, I love living in the country.
