What Happens To Ammo When It Burns?

For those curious about what happens to ammo when it burns, this is a very interesting and informative video and may help you determine how to store and manage your ammo.

(It should probably be a sticky once we figure out where it should live)

What happens when ammo cartridges burn? This video was created to educate and inform fire departments nationwide and to help firefighters better address the realities of fires in which sporting ammunition is present. The video was produced by the Sporting Arms and Ammunition Manufacturers' Institute (SAAMI), the standards-setting organization for the industry.

MythBusters tested this. Not much. Also had a friend whose house burned down with lots ammo in it due to some electrical issue in the home. Lots of popping but that was about it. Thanks for this video. Lots good info.
 
Mythbusters measured the bullet speed at 87 mph. One penetrated a ballistic gel body one inch.

In the high speed video it appeared the casing went in reverse even faster than the bullet.
 
I heard firefighters might decide to leave your house to burn if they view it as an endangerment to their lives
 
Mason Miller throws at 104 mph. That will hurt.
There is a hell of a difference between the mass of a bullet and the mass of a baseball. If you are hit by a bullet going
85 miles per hour, it’s merely annoying. If you are hit by a baseball going the same speed, it’s going to really hurt. Maybe even kill you.
 
Mythbusters measured the bullet speed at 87 mph. One penetrated a ballistic gel body one inch.

In the high speed video it appeared the casing went in reverse even faster than the bullet.
Makes sense as the casing weighs less and the shape of it captures more of the explosive force.
 
Yes ammo exposed to fire can go off however a bullet needs the pressure gained in a barrel to get velocity. Ammo that’s not in a gun will certainly pop and the actual projectile can move with some force but it’s not enough to penetrate the metal ammo can and a steel safe.
 
The only test I found surprising was the drop test, 2 rounds of .357SIG ignited.


.357SIG should be re-designated .320SIG.
