What would cause a round of ammo to go off on its own, if anything at all? I had a friend of mine say he had some rounds in storage that just went off by themselves which is kind of scary considering most people store ammo in their house. I mean I would bet the majority of people just have it stashed in their closets, under their bed, etc. A few may have it locked up but even so is that little lockbox going to keep a round inside of it if it does decide to go off, it is pretty doubtful. So, can anyone help a guy out and give me some info on this? Thanks.
