http://www.cabelas.com/product/Cabelas-Dry-Storage-Ammunition-Box/740706.uts In-store or by mail. I got a bunch of these already. Been using them for most everything (ammo, gun parts, knives, books, powder, primers, batteries) for over a year now. Love 'em. Gonna get some more now, 'cause Cabela's rarely puts these on sale anymore. Time to jump! For those of you who haven't tried them, I highly recommend them. They're "handy as a pocket on a shirt". Watertight as a duck's rear end. Holds almost twice as much as a GI steel .50cal ammo can. They stack solid and stable. You can store standard 8.5"x11" documents in one without folding. Buy a baker's dozen (13) or more and they'll ship 'em to you free anywhere in the lower 48. I don't know how long these are on sale for or how the long free shipping. So sooner is better than later if you want these.
