Smart Thinking: Video Of Brazilian Police Testing Incendiary Shotgun Rounds At Indoor Shooting Range, Causing Fire And Explosion

December 11, 2018

This is a video of the Civil Guard of Belém, Brazil doing some 12-gauge shotgun training at an indoor firing range with incendiary ammo. Personally, even I would have thought that was a bad idea, and I'm the undisputed king of thinking bad ideas are actually good ideas. Suck it, Florida Man. Some more info:

The incident happened in Belém, Brazil during training of the Civil Guard with 12-guage shotguns firing incendiary-effect type ammunition. The fire started on the left under the floor.


This may be a result of unburnt powder and dust on the range igniting.

Clean your range!!! Also, the range design is important.

Thankfully, nobody was injured in the incident despite that looking like a pretty serious blast. Maybe not the most serious blast I've ever seen, but I did just mention I'm the king of thinking bad ideas are actually good ideas. "Are you referencing the time you shot mortar fireworks up the chimney with the flue closed?" No, but that was also a doozie.

Keep going for the whole video, actual fire and explosion begins around 1:20.

Thanks to Greg C, who agrees that, like swinging a shower curtain rod around like a bo staff, some things are best practiced outside.

    to be fair, even if they're idiots that big fire at the shooter's feet really doesn't seem like something that should happen if the equipment was up to any kind of proper standards.

    I don't understand what caught fire, why it caught fire, or why there was such a big fire.

    Those things have ZERO recoil. They must be “Dragonfire" rounds, which are 12 gauge rounds loaded with powdered magnesium, the same material those camping fire starters are made of. When it is fired, the powdered magnesium is ignited as it flies down range, and it burns at super high temperatures. My guess is some of the powdered magnesium didn’t ignite and fell around the shooting point, then when enough of it built up it was ignited by subsequent rounds.

    I've read too that if indoor ranges aren't cleaned regularly there's risk of significant build up of unburned gun powder and dust that accumulates over time, that can be ignited.

  • Tigerh8r

    I din't think of that but it's probably closer to the answer. I'm thinking US ranges with required air scrubbers and directional flow, but this is in Brazil...

    That was literally in the article.

  • I guess we all know who started the fire.

    Plus person in there with sandals on, "Don't worry, all the heat leaves with the slug, that's why they're incendiary."

  • Bling Nye

    Why the fuck would they need to use incendiary shotgun rounds?

    "They're fuckin' cool!"

    Oh, well, ok then.

  • lushkneebumbuild

    how else do you check whether the methlab is safe to enter? it's like clearing a mineshaft of firedamp

  • Tigerh8r

    Tear gas rounds are expensive?

    Hire industrial designers. Or a few engineers.

    Mental note: Bring Gun powder to my christmas function...sprinkle it on the yule tide log.
    Lets the good times fly...
