What do you do when a phone company claims its phone can withstand the impact of a 9mm? You take it to the range and shoot it, thats what.

It's hilarious when you drop a full clip on the concrete floor!
So sweet...so in case I ever got lit up by a barrage of bullets, my phone will survive.
No I did not watch the video
I was a little more concerned with the loaded handgun he was holding when he was pointing it at the floor.
This was stupid. someone needs to give them some basic firearms instuction.
1. a .22 caliber weapon will be hard to stop then a 9mm.
2. they gave no consideration to the round. Was the round jacketed or a wad cutter?
3. They shoot it out of a rifle, why? a hand gun, any hand gun, is not comparable.
4. a .22 out of a handgun is still not comparable to a 9mm. a 9mm is more easily stopped then the .22
not saying the claim was not false but this did not disprove it.
A .22 handgun is not more powerful than a 9mm handgun. A 9mm round is much bigger and much more powerful. Why do you think police forces around the world use 9mm handguns and not .22?

That being said, that looked like a pistol range, and a rifle should not have been used (especially a .22lr rifle - those things fling bullets like nobody's business).
The standard velocity .22 Long Rifle takes a wax coated 40 grain RN lead bullet to a muzzle velocity of 1,138 fps. The muzzle energy is 116 ft. lbs. in a standard 22" rifle test barrel.
Typical factory loads for the .222 Remington drive a 50 grain spitzer bullet at a muzzle velocity (MV) of 3,140 fps with 1,094 ft. lbs. of muzzle energy (ME).
All you idiots saying a 22 is easier to stop than a 9mm need to actually take a physics class and/or shoot more stuff.
From real world observation putting on some static steel matches where both rimfire and centerfire pistols are used, and the steel plates are held up on stands made out of pressure treated 4x4, the 9mms often make it right through the 4x4s. The 22s do not.
kinetic energy = 1/2mv^2
22=1240fps and 40gr. Ke = 30752000 (using grains and feet for this doesn't yield small numbers unfortunately)
9mm = 1180fps and 115gr. = 80063000.
One of those numbers is clearly bigger.
I never saw the advertising claim, but usually for electronic devices, "surviving" means they work with a hole in them, not that they stop a bullet. This product clearly does neither. Bigger holes are harder to keep working through, so I don't think you need mythbusters on this one.
using your theory one would think that a .45 would be better at stopping someone then a .32. and you would be wrong.
all of us idiots that actually have a need for vest do study this sort of thing. kinetic energy does not equal penetration nor does it equal the effectiveness of a bullet. using your theory one would think that a .45 would be better at stopping someone then a .32. and you would be wrong. not saying that the claim isn't bogus but a .22 is not the same as a 9mm. your ignorance is showing here.

I would trust a thick pad of paper more than that cell phone to stop a bullet.
Plus all this ballistics talk is meaningless since there is no way to adequately relate it to either blood pressure drop or trauma to vital organs.
I think you should stop here. Or we will have to come up with something better to say than "your talking out of your ass without any real world experience"
Your talking about the surface area of a .22 vs 9mm. And yes more surface area does allow the bullet to stop faster but the kinetic energy of a 9mm hand gun cartridge trumps your surface area theory out the window when comparing it to a 22 long rifle cartridge no matter if it was shot from a rifle or a pistol.
