I was discussing with a friend of mine about a final demise in which he told me he was buying tons of 22 caliber ammo. We spoke about how it's hard to find on the shelves anymore, and how it's the cheapest ammo to shoot. His thoughts were that he could hold off attackers with 22 caliber ammo. I understand that when you shoot someone with 22 caliber it just bounces around, and never comes out. I still have to believe it's not enough.. What's everyone else thoughts?
