bullet proof glass

[Gilby959798]

so i went shooting with some friends today and they had a chunk of bullet proof glass that was about 1 foot square that was around 1-3/4" thick. it held up against the .22 and 40 cal pistols and then when i shot it with my sks it i broke out a corner and then my one friend shot it with his 444 and it pretty much destroyed it... so have any of you guys shot at any bullet proof glass or are any of you into shooting?

Thanks

I'm surprised your SKS didn't break the glass, unless it's Chinese of course LOL

it did break it a corner and then once it was broke out the stuff was kinda brittle

I like shooting things...

thats cool I wonder if the PS90 or the FNH57 could have broken it as well.

Not very helpful if your SKS could chip it then your buddy just destroyed it.

my sks took out a corner and its a 7.62x39mm 124gram shot where the other rifle was a 444 260 gram shot thats a lot more umph outta his

Not all bullet-resistant glass is the same. Its resistance to penetration depends on its thickness and how it's mounted, among other factors.

BTW, those bullets are weighed in grains, not grams. a 124 gram bullet would be over a quarter pound--or more than twice the weight of a .50BMG bullet. 124gr(ains) is about 0.02lbs.

Bullet proof glass is a myth.

No. The SS190 round is designed to defeat soft armor (vests), not hard armor.

I wonder what kind of glass it was. At 1 3/4" I'm guessing it was a polymer. The more exciting bullet resistant glasses are things like spinel and ALON. These are both slight variations of sapphire (Al2O3), because nobody has figured out how to make a large sapphire window.

One of the exciting technologies in my field is diamond-like carbon coatings. They're good now for certain things, but they are not yet diamond-like enough to be clear, for one thing (they're black). I expect that in my lifetime somebody will figure out how to make true 100% sp3 bonded diamond coatings, and it will be a real game changer.
