I was reading that the DoD is planning to implement using thermal stickers on cases of ammo that turn black to red when the ammo has been stored in unsafe temperatures. I did not know that there was a such a thing as an unsafe temperature for ammo. From experience, I know it get hella hot in some middle eastern countries and if there is an unsafe temperature, those places gets that hot. The article did not say how hot is unsafe. I would have assumed that until it is so hot that the ammo cooks off any temperature is safe.
Anyway, does that make sense? Is there an unsafe temperature for ammo, or is it a "just to be safe" thing?
