Anyone ever hear of accidental discharge of a round NOT loaded in a firearm? I've never really given it much thought, but I was reading the USMC Rifle Marksmanship manual, and I noticed it always says to make sure stored rounds in mags are always pointed away from the body. I suppose one could fire outside the gun, but I guess I over-estimate the safety of an individual round outside the weapon round. Could a carpenter's hammer hitting the rim or extremely long drop with a high impact landing (like from a roof or out a coupe story high window or something) fire one?? What about extreme heat? I always figured those were myths, but I guess it's worth asking. I stored about 500 .22lr rounds in my gun safe over the summer, where it got extremely hot. Subconsciously, I pointed the rounds down where they'd have to go through two layers of steel to get out of the safe, but I did it kind of without really thinking about it. Regardless, nothing happened. So anyway, how do you guys store your ammo, what are safe storage tips (without compromising security; I have 2 kids that are still learning and may be dangerously curious if they could find it)? Anyone ever hear of a round actually discharging accidentally without being in a chamber?
