As I read this thread, one thought occurred to me: if you're carrying thousands of rounds, you'd better pray they're mostly for long-term hunting.
This is not to say that I disapprove of self-defense, but think about it: if you are in the sort of war where you might have to shoot 1,000 rounds cumulatively, the only way for you to survive is if you're a part of an army.
*Alright, tornado warning went off. I'm now in my shelter. I still have wi-fi*
Anyway, if you have to shoot that much, you're probably fighting a large number of armed men. Without allies, logistical help, and medical care, you'll die fast.
