True but is not limited to shotguns and bolt guns?
I don't know the particulars, but there are Youtube videos out there of Australians shooting sniper rifles and other types of guns. They all appear to be living out of town.
Bolt guns and shotguns are extremely effective if applied in the right scenario. Guns like the AR15 are good general defensive weapons, but they definitely have their downfalls. Personally, I believe in the 1,000 defense. If you wait until the wolf is at your door, then it's too late.
