I have always bought ammo when I see it. If I'm in Wal-Mart and they have ten boxes of 22LR Brick I would always buy one or two. And still to this day when I'm in Wal-Mart I walk by the ammo case to see what they don't have. I have not seen a brick of 22LR in months. They never have handgun ammo like .38, .44mag, .357 or 9mm and I go two or three times a week and I have a guy in the sporting goods dept that looks out for me. If 22LR, 9mm, or .38 comes in he will hold a box of each for me, but he has not see any for weeks. So I buy shotgun shells every time, #2, #4 and #6 shot. I think shotgun shells will be as good as gold WTSHTF so I stock up. Just remember that after the collapse what you have on hand is it, unless you can find or barter for it. Getting the items we need for survival and stocking up on them now is the way to go. Tomorrow is gone and you can never get it back, so take today and use it for survival. Start a plan for life and stock up on food, water, and medical supplies and don't forget ammo and lots of it. If you don't have a gun I am telling you that you will need one and you will need to know how to use it.
