Freezing weather and ammo

[Pinhead]

I leave my gun in my car daily while at work. With cold weather finally here, the ammo in it would be exposed to repeated freeze/thaw temperatures. Would there be any detrimental effects because of that?

Thanks

Didn't appear to affect any of the shooting going on in Eastern and Western Europe during the period 1939-1945, so I'm assuming nothing has changed since then in ammunition design.

You may have to change out the summer air in your car's tires to winter air when the snow starts falling, but your ammunition should be good to go.

And I just had the valve stems lubed. Back to the shop, I guess.

Shouldn't bother it. Temp swings of 50 degrees or more over time will degrade it, it would take years.

Thanks for the reply

catching up on my RSS feeds, so a bit late here, but just to add to the unanimous response here, I've had ammunition repeatedly (back and forth) exposed to 20s to dry 130+/- before finally expended, haven't had any failures out of the norm.
