So at 13:14, after the shooting is over, he is driving and shoots his own front windshield 3 times with a shotgun and it does not break. But then shoots the side window and it explodes. Can anyone explain this?

The only thing i can think of, (not being a gun user) is that having the nozzle (or whatever it's called) right against the glass like that makes it impossible for the bullet to gain any "play" against the slick surface of the glass? I only say such a silly thing bc the bullets, if iirc, kind if slide along the surface and drop to the dash (I might have to watch again.)

Gun people, would you need an inch or two for the bullets to have enough momentum to be able to pierce the glass?

But the pellets (shotguns shoot like 100 BBs all at once called a shell cartridge, rather than a bullet) have already travelled the full length of the barrel of the gun, so they're already at max speed.

I guess it's possible the shallow angle of the front window caused them to bounce and reflect downward in to the dashboard... but seems very weird and unlikely. And probably would've also maybe messed up the electronics in his dashboard to take several gun shots like that. I don't even see what he was shooting at. Just seems weird.

Here's a video of a cop shooting through his windshield, 8 seconds in, the bullets pass right through and the windshield cracks: https://www.youtube.com/watch?v=1EnuL92vAG8

That's even a small handgun, a shotgun is more powerful than that.

Maybe the guy had a bulletproof front windshield installed and was shooting it for "fun" out of impatience. But it did seem like was trying to aim at something when he shot.

I am still super confused.

They're both designed not to break. Since the side window was all together when the shotgun hit it, it was more likely to distribute the force. The front windshield is thicker too if that changes anything.

Interesting, but I'd think 3 shotgun shots would at least damage it... Here's a cop shooting right through his windshield with a handgun (8 seconds in): https://www.youtube.com/watch?v=1EnuL92vAG8

I just kind of have a hard time believing a shotgun doesn't damage it at all... but I guess it's possible. And I guess the low quality of the video may make it harder to see any cracks that did develop.

To me the difference is that the officer is shooting at the part of the windscreen that is less angled, and has about four inches of space before the bullet makes impact.

NZ bozo has the gun right against the glass, at the bottom where the screen is at the most acute angle. I dunno. The physics of firearms is not my area of expertise.

The guy seems highly trained (and on major roids) and I almost wonder if he was doing that as a game? Like knowing it wouldn't shatter, and "shooting" at people like you might "squeeze their tiny head"?

I'm no expert but I know a fair deal, and it just doesn't make up the difference to me.

I have come to believe it punched holes in the glass, like in the cop video. And the holes are just too small and poorly-defined to see in the low-quality video. That's what I've decided makes the most sense, until I see any info that contradicts that

That cloudiness on the bottom of the windscreen--can you tell if it is powder/smoke residue or crazing of the glass? As someone who has only shot guns at bottles in the distance, I can't tell what's going on in the video.

Ok I watched that part like 5 more times.

I think maybe his gun misfired? After the first two cartridges it seems like they jammed, he actually pulls a cartridge out of the gun by hand instead of ejecting it, which is odd. Then I noticed after the 3rd shot at the windshield I think it actually did fracture the glass in a rough circle shape right at the bottom, it turns frosty-looking in a small spot only after that 3rd shot. Then he immediately decides to instead aim at a side-window instead, seeing the damage and how it didn't go through.

I'm going with 2 misfires, followed by a 3rd real shot, that only fractured the windshield in that one tiny spot.

This is late, but I just made an account. Every round the shooter actually fired, which you can tell from the noise, went through the windshield. It's just hard to see in 240p and since the first holes are so low that from the camera's perspective they are a similar color to the hood. The gun jammed because the shooter is pumping in a confined space, so he didn't pump hard enough to fully chamber a cartridge. Also, the front windshield and side window are not the exact same glass. They are both tempered glass, but the front windshield is laminated which is why it doesn't shatter.

Thanks for the explanation, makes perfect sense

[–]useless_aether 2 insightful - 1 fun2 insightful - 0 fun3 insightful - 1 fun -  (1 child)

they are made differently, the manufacturing, tempering is not the same. i think there is a foil in the ws that holds it all together

[–]magnora7 1 insightful - 1 fun1 insightful - 0 fun2 insightful - 1 fun -  (0 children)

Yeah the front windshield has a plastic laminate layer in it that keeps it from shattering
