I live on a 1.5 Acre Lot with my House on the center of it. There is Woods behind me, and a another house directly across the road. Although I own several M14 type semi Rifles and a few semi AKs, and Ar15s, I would not consider a Rifle. If some AH Kicks in a door, or tries to come through a Window, and Brutus, my Professionally trained German Shepard can't handle the situation, I have my Remington 870 20" BBL Loaded with 2 3/4" OO buck to back up my fully loaded CZ75, and Mrs Nipper has her 686 357. As Mr T would say "I Pity the Poor Fool".
