    Ammo in the desert heat

    First, I did search and anything to do with the subject was years old and really didn't cover this.

    I frequently drive and camp in the desert. Even during mid-summer. The ambient temps can reach 120 degrees and higher.
    What precautions do I need to take to protect my ammo?
    I know the temps aren't going to cause the ammo to explode but will it degrade it over time?
    I also know to not leave it laying in the direct sun.
    I usually travel with a fridge (Engel) so I do have access to a cool place. Would taking the ammo from the 37* fridge to the 120* air do anything harmful to the ammo?

    I never shot in that heat. In the hot part of August I keep my rounds in the shade. The heat will affect them. There a plenty of stories about the solders "cooking" the ammo. I would worry about condensation from the cold to hot. I am not sure about the heat and longevity of your ammo but the ammo you expose to the heat should be used and replaced. Try and rotate it.

    I've been in the Phoenix area for just about 10 years now. There's always some ammo in my car and more in my garage, and there's never been a problem. I wouldn't make a point to store ammo in a fridge - there's no need. In a humid environment you'll get condensation forming on stuff coming right out of a freezer, but that's hardly going to be a problem if the ambient temp is 120 F.

    5.56 and .50 BMG loaded in mags, ammo cans, and belts in the gun. Ambient temp highs- 128 F. Temps in the HMMWV, who knows? 100% reliable.

    caveat- Military ammo is sealed.

    Like smitty, I'd also be more concerned about ammo cooling and condensation. Heat dries humidity. Cold condenses it.

    See this thread from 2011:

    What point is temperature too hot for ammo?
