Eli5: Why are guns with blank cartridges still potentially fatal?

362 views

I am not referring to a scenario where one cartridge has a bullet in it. I have read of a specific case where a blank cartridge was fired and yet the person still died. If no bullet was in the round, how could it kill someone?

There’s still a REALLY high amount of kinetic energy in the gasses going out of the barrel. Not much range due to the jet dispersing in the comparativelly-low-pressure air around it, but at close range it carries a really considerable amount of force.

Same thing as with RPG launcher backblast from its rocket – there’s nothing going out from behind but the rocket exhaust, but it is still rocket exhaust plume, and it carries equivalent kinetic energy to the one that launches that rocket.

High pressure systems in general can be REALLY deadly, and that blank going off in a barrel is just one example of those.

It still has the explosive charge, it’s just not launching a projectile. But the gunpowder can still burn and deafen.

And if you’re blocking the barrel, say, firing a blank against your hand, that pressure has to get out still. Your hand would essentially become the bullet.

The air and gasses from the burning gunpowder can *be* a bullet if they’re moving fast enough, like water in a water-jet cutter. They spread out and slow down *pretty* quickly once they leave the barrel, but not instantly.

I know of 3 cases.

Iirc.

One there was a magician, he tapped the gun and the tip of his wand fell in the barrel. The blank then fired the tip from the wand that was in the barrel into him during the trick and killed him.

An actor took a gun with a blank, pointed at his head it was believed iirc that he didn’t intend to kill himself but didn’t realize it would be fatal when he pulled the trigger. In This case it was just the energy coming out of the barrel that penetrated his skull.

Then there was another case I think the crow, that one had a bullet, no charge but they forgot and left the primer I which is a smaller charge that sets off the gunpowder, but was enough to launch the bullet and kill him. So not exactly a blank.
