The glass is not bullet proof.
The stainless steel doors are small caliber bullet proof.
Resistant
There is no guarantee to stop even a small caliber
Small caliber at high velocity would go straight through
You could say a thick metal wall is small caliber bullet proof because no matter what velocity, the small chunk of metal is never passing through a few decimeters of solid metal.
Small caliber piercing round at high velocity, straight through the stainless steel door.
Slap some plastic on that bad boy
You'd really trust that as a bullet shield?
Normal 9mm across the street. Probably going through
For the record a decimeter is about 4 inches. "a few decimeters of metal" is a lot of metal.
Yep small caliber proof for sure
My favorite part of decimeters is 1 inch is 1/4 decimeters. 3 decimeters is foot.
So if it's like 8 inches. I can just say 2 decimeters
From there you can say 20 centimeters or .2 meters
If something is 12ft it's 36 decimeters or 3.6 meters
There's no easy way to turn 8 inches into centimeters other than knowing that 1 inch is about 2.5 centimeters or just estimating in centimeters to begin with.
You could say 8 inches is 2/3 of a foot. 3ft to a meter. So 1 ft is .30 meters. Then it's 2/3 of a foot, so .30×2/3=.2.
Decimeters are the missing link for Americans to convert
Yards to meters is 1
Feet to meters is 3
Inches to decimeters is 4
Things like a 36 inch doorway, 3 feet, would be 9 decimeters or .9 meters
Common measurements of inches:
12 - 4 Decimeters
18 - 4.5 Decimeters
24 - 8 Decimeters
30 - 9.5 Decimeters
What they would use otherwise would be
.4 meters
.45 meters
.8 meters
.95 meters
Saying the standard doorway is 9 Decimeters is way better than saying .9 meters.
If you rounded to 1 meter. You're adding 3 1/3 inches. Which is a 10% increase.
A decimeter tape measure would be nice.
There are plenty of videos out there showing it stopping repeated 9mm bullets. But you're right, the velocity will also come into play.
Yeah, I watched one from official Tesla youtube where the guy shot it with a bunch of stuff.
It did stop the 9mm with the rounds they chose
The buck shot pierced the door and cracked the window because it was rolled down.
Buck shot is smaller caliber with higher velocity.
I need to find a video of someone trying to get a 9mm bullet to go through it rather than basically a paid advertisement.
This one is recent and it does various calibers / velocities
https://www.youtube.com/watch?v=ufoLITv26R4
it did stop a subsonic and supersonic 9mm. The supersonic one was pretty close to going through though, I wouldn't have been surprised if he did a dozen or so if one would have.
The shots that ripped the metal instead of piercing through it were pretty wild.
