Heat & Ammo Question

I have always been taught that the old wild west movie stuff about a cowboy tossing cartridges into the camp fire and have them go off was bogus. Excessive heat (like a house fire)can ignite the powder but by then the brass has softened to a point where there was no good seal and the bullet just limped out. Am I wrong? Channel 8 in Indy just had a segment about explosions from ammo in a house fire last night.

It's too late for me, save yourself.

but a bullet's power comes from the fact that the chamber contains the explosion of the cartridge, so nearly all the pressure escapes down the bore. Without this containment, a bullet has very little power, but it still has enough to hurt you if you're too close.

My buddy leaned over the campfire to stoke it and out of his parka pocket went a bunch of loose .22 shells. Well they stated going off and we were all diving for cover. Luckily no one hit other than 1 tent with a round through it, maybe 15' from the fire. So I personally know that it is not a myth.

The sort of dumb stuff kids due. Camp fires and throwing stuff in em, sorta makes sense (not that we had any) that what ever is the heaviest sends the other flying more.. All i know is you start ducking quick, and never heard of anybody being badly hurt by this.. I know theres not much in the world thats more fun than sitting around a fire, and listening to guys talk about the stupid stuff weve all done.. sorta a burning confesional, after a couple, the funny and true screw ups come out.. Thats the only time ive ever told about my accidental discharges. I was told 30 plus years ago that you werent a shooter till you had an AD, was like..no way, not this boy.. Well guess im a real shooter now. I've had two, both embarrising, both stone sober, both stupid. The back up safty stuff we follow kept them from being more than embarrising storys, but should we ever sit around a fire you'll hear them.

a man has to hold his word, hold his beliefs, and hold a good sight picture.

are unable to resist the urge to spit into a campfire. My mom always said the smoke follows the bad kid. Usually after hearing me complain that I can't get away from it.

Rounds travel in the

Rounds travel in the direction of the least resistance. The bullet generally outweighs the shell casing, so when the powder/propellant ignites creating the violent explosion we have all come to love, causes the projectile to become the shell casing itself as opposed to the ogive/round. You can definitely suffer great bodily injury or death from the velocity of the casing, while being slower since there is not a constant pressure behind it like there is on the back of a bullet with the gases from the bullet going off being pushed out of the chamber along the barrel and out the muzzle. Occasionally the bullet will still be the projectile if when the round goes off, the casing was up against a surface, then the casing cannot be pushed away to let the gasses escape and the projectile will fire outwards. Heat/fire definitely will set off rounds, just as the spark/flame from the primer will ignite the booster charge, or the main propellant (Usually nitrocellulose unless you are using real old ammo, or another powder) and then the danger begins. Hopefully this has helped?

If you are not just a little bit crazy, then you are not quite sane...
