I don't know exactly what tempature is needed to cook off a live round, but I have never heard stories of ammo cooking off in Iraq while stored in a vehicle or on someones person. I remember thinking about this when I left a bunch of ammo in the truck during a mid summer range trip. I figure desert temps reach 120 all the time.
Anyone know what temps rounds cook off at?
The OP should also know that while his employer may no be able to search his vehicle, refusal would probably result in his termination.
From a summary on the mythbusters episode :
For people that don't watch MythBusters on a regular basis, their most recent episode tested two scenarios of cooking off ammo. The first scenario was storing loaded guns and loose ammo in a stove, forgetting it was there and subsequently preheating the oven. The second scenario was throwing loose ammo into a campfire. I'm assuming the campfire test would be similar to having loose ammo in a house that is on fire. The MythBusters used a mix of .22, .44 and .50 BMG ammo in each scenario.
The general consensus of the results were that the brass cases were much more dangerous than the bullets themselves. Under heat (typically less than 500 degrees) the cases would split exposing sharp shrapnel-like edges as they were separating from the bullets. Being lighter than the bullets, the cases would also separate at significantly greater speeds. The MythBusters (Jamie and Adam) felt that although probably not lethal, you would be quite bloody if you were close to loose ammo under these circumstances.
The loaded handgun was only tested in the oven scenario. They used a revolver and predictably it seemed to be as lethal as pulling the trigger would have been. Although the results are rather intuitive (if you think about it), it's always entertaing to see these guys blow stuff up. The epsidode is titled "Red Rag to a Bull" and makes no mention of setting ammo on fire. The episode description is "Jamie and Adam learn whether red rags really affect bulls". It will be re-broadcast tonight (Thursday 8/23) at 7:00 PM on the Discovery channel.
If you watch this episode until the very end, you will also get to see them use the campfire to blow up a keg of beer (the horror
