    How stable is ammo?

    Reading in a recent thread about carrying extra magazines, some have said that they leave an extra mag or extra box in the car. Here in AZ, a 114 air temp in the shade day is not that rare in the summer and the interior of a locked car can be quite a bit warmer.

    So, my question is: How hot is too hot for ammo in the console? Blowing up a cartridge is not the same as blowing up an unopened can of Coke (yep, done that...)

    Is this a real risk ?

    Electricity

    Has there ever been a case anyones heard of where someones discharged a round from electric shock, something that might occur when welding or doing electrical work? Granted, it would have to be a weird series of events to happen. But say your welding, you lean on the table and the gun makes a ground and the electrode in your hand makes contact with said hand?

    I have never heard of this but this seems as appropriate a place to ask just cuz.

    You have to remember that being inside the console actually shields the ammo from direct sunlight and may be a few degrees cooler than the vehicle interior. Long term temps like that might degrade ammo however.

    Even in July you have more risk of melting the plastic parts on your mag than anything. I've never had a problem and have never heard of anyone having an issue with ammo cook off in the car.

    No problem with the heat here in Alabama. Not as hot as AZ, but still pretty warm. You should not have a problem.

    Not a problem!

    If you think about it, when the ammo is shipped, it is in a hot box van for God only know how long and it is not in a controled climate. So when you buy new ammo, it is very likely it has already been subjected to that kind of heat!

    Mythbusters did an investigation on this. They had to get an oven to around 500 degrees F to get them to pop.

    No way a round is going to explode due to heat inside a vehicle unless it's on fire that is.

    I try to keep my ammo supply in as cool and dry of a place as possible. My office closet is where I store it for safe keeping. Just makes good practice to store it as instructed, so it will keep.

    I welded my mothers muffler on her truck with gun & spare mag ;
    Wouldn't welding rods have worked better???

    I would think the gun would make a better riveter then welder.

    This is a good and legitimate question. I asked it on another forum some time ago. If you're using good quality factory ammo then it should be very stable. Ammo will not explode if left out in the sun or in a hot car. Think of soldiers in the desert and all that ammo sitting in the hot sun and stored in vehicles. For a round to "cook off" it has to get VERY hot like in an oven or if thrown into a fire. I had a firearms instructor tell me that when they went to the beach in July in South Carolina. They left ammo and firearms in the car trunk with no problems. For long term storage ammo should be kept in a cool, dry place.
