definitely check out "the box o truth" website. I've not seen any armor-slugs, but here in Montana I have the opportunity to try many types of exotic rounds in my backyard! unfortunately most of them seem to be a waste of money, as they do not perform as well as good ol buckshot or slugs. Some ammo such as the flechette is a total waste. If i need to defend against armored vehicles I'm going to use track shoes! Run Joey, run!
