house Fire in Aurora, Ammo is poppin.

OMG!! What a waste of ammo... facepalm

Hope everyone is ok and its no one on here, i know most of us keep more than that on hand anyways.

So ammo explodes now, huh? That's an interesting development. My physics and chemistry professors taught me that gunpowder does not explode. It just burns. Well, it is "TheDenverChannel" so I guess I better take their word for it.

The is a difference between deflagration (what guns do) and detonation. Gunpowder Deflagrates.

Deflagration is basically a fast burn of combustible material. A black powder pipe-bomb deflagrates.

Detonation is a supersonic shock via chemical reaction. C4 explodes via shock caused by a detonator.

Thank you for the technical definition. I had forgotten the word "deflagration".

But back to the news story: I'm just concerned that the guy only had 3k rounds in his house... Maybe he only had 1 gun? I would say 3k is a minimum for each gun!

Getting kind of close. Black Powder in a sufficient pressure vessel certainly causes a detonation. Detonation is not only due to chemical means. Remember, just because it is on Wikipedia does not make it right. Detonations and deflagrations are characterized by the speed of the burn vs. the expansion rate of the products. While there are generalized speeds we use, supersonic (which is the speed of sound in air) has no bearing on the classification. Due to densities, about 3100 fps is typically seen as the common threshold for a detonation. Some reactions go from one to the other as well, so it is not universal.

I was not using Wikipedia.

This is the definition of detonation that was taught to me:
A detonation is classed as an explosion. It is a chemical reaction that propagates with such rapidity that the rate of advance of the reaction zone into the unreacted material exceeds the velocity of sound in the unreacted material.

And from what I understand the deflagration/detonation threshold is 1000m/s (3200 fps) not 3100 fps but that is just semantics.

There is a saami video where they set a pallet of ammo on fire.....no explosions

Aurora has its own laws of physics and chemistry.

Ohhhhhhhh! Now I understand why they are so f*cking backwards!
