Exploding ammo

[Tokoloshe Safaris]

Leaving ammunition on the dash of a vehicle is a definite no,no, but has anyone heard of ammo exploding on the dash of a vehicle while left in the sun?

Does anyone have any data on temp required? Which ignite first primer or powder?

Just curious.

No info, Lon BUT I have been told by a Yank gunsmith who is resident in New Zealand, that the story about ammo exploding in vehicles comes from idiot poachers in the U.S. who accidentally discharge their .22 Rimfire rifles inside their vehicles on the public highway; and try to bullshit their way out of it. I understand that some of these people may be active during bow hunting seasons.

I’ve heard the story. I think they were in Deliverance.

While clearing a residential plot we were constantly getting “whump” and throw a bit of ash into the air. Some whumps were louder than others.

Still wondering about dashboard.

That’s definitely the first I’ve ever heard that story. I think that’s a tall tale only found in New Zealand now! In Pennsylvania at least, if you have a firearm while spotlighting from vehicle you are in violation of law, no excuse of an accidental discharge will help if caught.

Yeah, those shells can get pretty hot by the light of the moon at 3:00 a.m. That's when most deer poachers are typically doing business. Uh ... well ... so I've been told.

Ignition temperature for smokeless powder (depending of type) 350°F to 500°F (about 177°C to 260°C).
Ignition temperatures for primer chemicals: 250°F to 300°F (approximately 121°C to 149°C)
Unlikely, to impossible

Various armies go to extreme climates. I never heard of army ammunition self igniting on sun.
Civilian ammo, never heard of it.
