Why do any of you think in terms of how much ammo you can carry?
Have you paid attention to nothing? Do you not know about caches?
Why would you have all your ammo in one place if you have more than you can carry on you?
I believe a while ago I posted the Special Forces Manual on Caches. You should definitely check it out.
If you've got 50 or 20 thousand rounds, by all means, please cache some of it, in strategic places that will be most advantageous to you.
I'd love to have 50 thousand rounds, but by all means, I would never keep them all in my house. Thus, 50,000 rounds is plenty enough as long as you've prepped in all the other areas just as much. You just need to cache some of it. With ammo, its really, never is enough, as long as you've prepped sufficiently in all other areas as well.
