Plastic Dry Boxes as Good as Metal ? :confused:

    I have begun to hoard ammunition and I need some fellow THR stockpiling advice. :D

    At the moment, my rather small supply of .45 ACP (1200 rounds), is sitting in stacks of factory boxes in my closet. :uhoh: I figure this is as good a place as any, in terms of heat and humidity. I have always wanted to get my mitts on some ammo cans, but most of the ones I found at my local Gander Mountain are extremely rusty. More so than just “lovingly used” too, unless they were used by Navy SEAL Scuba Attack teams. :scrutiny:

    Anyways they do have plastic dry boxes however. They seem pretty nice, but are they as able as the military ammo cans at keeping out moisture and heat? They do have a rubber seal. Only downside I see is they don’t stack as well as the military ones.

    Most plastics are not as airtight as metal or glass. That said, they should work fine.

    I think plastic is more pourous than metal (our race fuel comes in metal drums as I've heard plastic cans can lose octane and absorb moisture). Just throw a couple packets of dessicant in the plastic boxes and they should be fine. Make sure they are sturdy and have durable handles/latches, ammo is heavy.

    You can get the metal cans online although the shipping charges seem to make them a last resort option.

    I probably want airtight, as I think I may move my ammo to the basement, so that I have room in my closet for urm... clothes.

    Any idea where I can find ammo cans? I guess I can always wait till my next gun show.

    Edit: I figured online shipping would be out there. I'll wait for a gun show. Thanks!

    Pick up some surplus ammo cans online, they are fairly cheap ($20 per).

    I grabbed some 20mm cans when I was in the Navy, I couldn't let them toss them. They are good. They stack ok (flat top and bottom), not interlocking or anything like that. They have a seal. The only down side is they are tall and narrow, you can put a lot in there it's just hard to remember what all is in it. If you are as crazy anal-retentive as I am and don't have a whole bunch of a lot ( ie. in my 9mm can-10 boxes of JHP 20 boxes of FMJ, 8 boxes of ball) it's hard to organize. The .40 and .223 are easier to sort because I have more.

    Surely, there has to be an Army/Navy store in a town as big as Pittsburgh. That would be the best place to find ammo cans in good condition. I can regularly find 50 cal surplus cans in perfect condition for $5-$7. Bigger ones go in the $10-$20 range (not rusty, great shape). Then, just get some of the SMALL silica gel packs (usually $4-$6 each at Gander Mountain, should be located near the gun safes), and throw one in each can. The same system (ammo can/silica gel) keeps the surplus ammo in good shape for decades in warehouses, so it ought to keep ammo in your house (68-78 degrees F) stable for the next century!!!

    P.S. Those "81mm" cans on that Coleman's website are NOT air/water tight!! Those 20 mm ones look pretty good, though, and will hold quite a bit of ammo>

    The MTM "dry boxes" are NOT waterproof.

    There has to be a pawn shop that sells them. Around here they can go for about four dollars. I dont know sizes but i imagine its a good deal.

    Surplus USGI ammo cans will be more rugged and cheaper. I've had good luck with the ones I've bought from MidwayUSA -- they've been clean with good seals.

    MidwayUSA has a sale on ammo cans thru the end of the month.

    Keep your ammo in the closet - it's temp and humidity controlled. Oh, and you have too many clothes!

    ammo storage

    I have always thought that the metal boxes would be better. The short 50 cal boxes are the best size. Larger ones are very heavy when full. You will not have a problem with the weight but others in your family might.

    Plastic will "creep" over time from the clamping force and the weight of the contents. This will cause the sealing force to be diminished and potentially leak.

    A dry area in your basement would be a good spot to maintain the proper temperature range. Excessive heat/cold can be just as damaging as moisture.

    Hope this helps you.

    I use all metal. I have been buying mine from Widener’s. Taking into account S&H for online and tax for local purchases, buying the 9-packs from Widener’s is the best deal for me. I called the local PX store and was not impressed with their price. I buy grade A, which always have a little rust, and occasionally a ding or two. I have a mixture of short and tall 50 cal’s. Mixing can making stacking difficult, but mine are going on shelves. Having a few of the tall 50 cal’s can come in handy. Packed, the tall 50 cal’s can be heavy, but that is relative to the person moving them.

    Exactly, which is why when I worked for an auto parts store, I recommended people buy Octane booster that was in metal containers and not plastic ones.

    If you're talking long term storage of centerfire ammo anything more than keeping the stuff out of the rain is probably overkill. As long as the crimp is good, and the primer in tight (maybe seal with some nail polish) tossing it in a bucket in a closet will suffice to keep it good for a 100 or so years (lots of folk - many here I'd guess I have fired 50 year or older centerfire smokeless cartridges and some as old as 100 years).

    But if you really want to make sure centerfire ammo keeps here's a good method.

    1. Wrap each cartridge box tightly in aluminum foil (non porous to air). If you're really anal apply superglue to the folded edges (prior to folding of course) to completely seal.

    2. Put as many boxes as reasonable in a vacuum seal bag and then vacuum seal.

    3. Take that package and an appropriate number of silica gel packs and store in any decent ammo can with a rubber gasket - though a standard .50 Cal can will work just as good (I don't remember if they've got a gasket or not).

    Ammo stored like that should/will last a 100 years - probably more.

    4. If you're really, really anal ;) - wrap the ammo can tightly in aluminum foil, place in suitable vacuum sealable bag and vacuum seal it. You could probably bury that and if some archaeologist digs it up a 1000 years from now all he'd need to use the ammo would be a gun to shoot it.

    maybe I missed it.... but there HAS to be a way to buy new military grade ammo cans.... rather than surplus. Surely the military buys them from somewhere, so..... where?

    Or am I wrong and they manufacture them?

    a mil surplus store here always has ammo cans reasonbly priced. I gave up trying to pick out a few of the best ones, all of them were like new. Priced from $2 to $5 to $7. I bought several and they work great. Tested them with the hose and no leaks.
    Gotta be a surplus store somewhere near you
