Here is the whole deal with all of this "How much ammo" stuff. First off let me say I keep plenty, and I'm not saying anyone else should not to do the same. But from a more practical standpoint, let's say this whole "Armageddon" thing were to play out the way people like to talk about it on forums like this one. Complete monetary collapse, power grid failure, food shortages, the whole nine yards. Now what? How the hell are you going to move all of this ammo, and just where the hell are you supposed to move it to? In all of this "survivalist talk" people right away mention "bug out bags". Having everything you require self contained, along with full tanks of fuel in your vehicles, all so you can grab it and run in a moments notice when "Armageddon" happens, and haul ass out of the city.

That means leaving the bulk of your ammo bunker for someone else to claim when your city dwelling gets overrun. And if you play out this "Armageddon" fantasy, everyone concurs that the city is the worst place to be, yet it's where most of us live. Because there aren't many places to earn a living on top of a 8,000 ft. mountain, in the middle of nowhere. Now, let's say you've got a remote cabin. Are you going to keep thousands of dollars worth of ammunition there where it can easily be burglarized by a couple of kids on ATV's when you're not there? My point is having ammo for the sole purpose of having ammo is fine. But in all reality, if society were in fact to completely melt down, it really isn't going to do you much good. In fact it would be a hindrance instead of an asset. And forget all of this, "trading bullets for silver and beans" nonsense. If things got that bad, no one is going to "trade" with you for anything. They'll simply kill you for it.
