For the whole thread: Whoo! I've always wanted to shoot something automatic, but never find a good range in my area of Kalifornia.

For the home defence: 12ga shotgun like a Mossberg 500 or Remington 800 serise. And get addons, like a sling, clips, underbarrel high power light (which can actually stop some people without a shot being fired). And then become a master with it.

If you dont go shotgun, use perhaps a frangible round to minimize the wall penetration if you miss.
