Winter ammo storage outside.?

[john442]

Quick question, can I store .223 aND 12ga slugs in a storage unit that is not heated? Will it harm it at all?
Cheers

The cold itself will not harm the ammo, it's the freeze/thaw part that will. If the temperature remains the same, I can't see any issues but having the temperature fluctuating might cause condensation issues.

^^ x2 ^^ You might be able to store them in an insulated container to limit the freeze thaw problem. I know you can buy containers meant to store ammo while buried.

I have been storing ammo. primers and powder out doors in a shed for about 25 years years and lots of it and never had an issue so far
May see the odd bit of tarnish on a couple pieces of brass but is cleans right off and works just fine

Ammo can's seem to work nicely for this application

The only thing you have to worry about (that I can think of) is moisture. If you store your ammunition in a hermetically sealed container that has been purged of moisture prior to sealing, then you do not have to worry about internal condensation from fluctuating temperatures. This can be done using a desiccant such as silica gel packs or calcium chloride.

To answer your questions, yes you can and no it will not harm your ammo when done properly.

Add: Like others have already mentioned, MTM ammo cans are built for this purpose.
