"Stocking up". Interesting words, and fits the appearance. My saferoom looks like a store. All items properly shelved. I don't keep a large supply for some "pending" ill future happening to America, other than rising costs of ammo. I buy as much as I can afford. Of the weekly uses, I too fire one box, and buy 2 or 3 boxes.
Here is the why to stock up. At present, the economy isn't great, and isn't horrid. It's falling though. As the economy continues to worsen, prices rise, and wages freeze, in the future I "might" not be as easily able to afford ammo. I view an ammunition supply the same as I view funds invested. Most of the ammo that I have, I have had for years. It is (on average) worth 2 to 3 times what I paid. Good investment.
Of all firearms I own, the greatest supply I have is .22LR. Oh sure, I have the "others", but in serious quantities, .22LR. Every hunter/shooter in America should have at the least 5,000 rounds of the preferred .22LR. Don't forget BBs and pellets too. No, I'm not joking.
