dump them in a ammo can and drop in a box end so you will know what they are when you open them years from now. i have stored ammo in ammo cans, coffee cans, factory boxes in drawers, in sockes, etc....... some were put in the cans in the early 80's. they all have gone bang. even the one that looked like crap, old 30 year russian ammo will turn green. when you buy bulk packs of 22lr ammo, the rounds are just dropped in a box. you can put lots of 22lr ammo in a ammo can.
One advantage to keeping the ammo in original boxes (in an ammo can) is that you can keep track of the LOT. Say you dump 6,000 rounds of ammo into 3 ammo cans, 2 years from now you're at the range, and you have a squib. Two mags later you have 2 dud primers in a row. Next mag you get a double charge and bulge your barrel. Do you remember what the lot number was on those 40 boxes of 50 rounds you just dumped into the can? Were there other boxes from the same lot that you dumped into the other 2 full ammo cans? How do you contact the manufacturer to notify them of a bad lot? Do you risk shooting the rest of your ammo?
If you have a fire and have guns AND ammo both in the same safe. It's likely the ammo will cook off inside the safe adding greatly to the heat and damage to the guns. BTW, if the firemen detect ammo cooking off they might back away from your house fire.
Just a thought because I've seen it happen........UGH
Thanks for the advice all. I'm re packing the safe now making room for the WASR and 7000 of his friends.
I have a ton (almost literally) of ammo stored, much is the ChiCom 7.62X39 steel core in sardine cans in the wooded crates, some was in wood crates in commercial type boxes (7.62X39, 7.62X51, 5.56).
This I took ammo out of the boxes put in GI ammo cans, I put the cans in the sun to warm up, threw in a silica gel pack and 1 flattened box for ID and closed, I have opened 1 can and it was near impossible, I had to sun warm the can again, in an emergency I may have to drill to break the seal. This ammo should be good for 100 years, I have shot 30-06 that was stamped from the 1940s stored in ammo cans with no problem.
Here's a link to the SAAMI "recommendations" for storing ammunition. Bear in mind, in some states, state law and/or local municipality ordinances may apply as to quantity amd method of storage.
I found the info about ammo in a fire interesting.
I put mine in Lock'n'Lock containers with the end tab of the box they are from so I know what date code they are in case of a recall.
