“I asked a fireman what happens to ammo in a house fire. He said, “It just goes pop, pop, pop. You’d be hard pressed to get hurt by it.””
Not entirely true. Check out demolition ranch on youtube. He puts a fifty cal round in a microwave. It had enough force to blow the door off the microwave. I wouldn’t want to get hit by that, though the odds of getting hit are slim, but if you had enough cooking off, I don’t know. I am also pretty sure your firefighter friend would not go running into a burning gun ammo factory.
Still, a few rounds cooking off in a fire, I agree, is probably not the biggest concern when entering a burning residence. Gas, electric, other household combustibles, heck, a soup can can cook off with some pretty good force (don’t ask how I know). Noxious fumes are probably the greatest concern, though there is a group of firefighters sueing claiming the sirens are damaging their hearing.
I’m guessing fifty-cals are rare in house fires. (I do have a pound of black powder in a can...)
