This is so mall ninja-ish. Even in a TEOTWAWKI situation, the odds of surviving long enough to need thousands of rounds is miniscule compared to the odds of dying from lack of nutrition or medical care or a hundred other causes.
To the OP: you have plenty of calibers, don't need to add more esoteric ones like .357 Sig. Frankly, in most situations a Glock or two and a long gun with a couple of mags each is going to be more than enough. You're not going to be living Red Dawn. A couple of weeks
of food and water? We should be talking months or years before we're talking thousands of rounds of ammo.
