What’s your guess?

@Johnny B Goode – Perhaps, but it only took one of the hollow-point SS195LF rounds from the FiveSeveN to penetrate…
Why can’t someone invent a 22 caliber or 22 Magnum that will shoot a flat trajectory like the 17 Caliber? We can send Men to the Moon. Use 10 different Metals if necessary.
Cool experiment! I like how bulletproof glass is behaving in this video, nice post!
The correct term is bullet resistant glass. And there are many calibers that will go through, and to the commenter about SeaWorld aquarium glass, is actually acrylic and usually 5 – 8 inches thick. My job is installing glass just to clear up some confusion between the writers.
Since you started with one of the smaller calibers, it would be great to see the same experiment with a large pistol caliber like 357 or a 44 mag since both are common.
Haters gonna hate, but I see tons of valuable info here. Cars are not the only things to use BP glass. Bank teller windows, gas stations and Sea World come to mind. I might chuckle a little if I was a bank employee behind that glass and a robber pulled out a 10/22. Conversely, I might change my tune if he unzipped a duffle bag full of 25rd mags. I don’t recall the title of the movie, but it was foreign, I think Korean. In the final scene, the bad guy jumps inside his armored car in an attempt to get away from the good guy who is hot on his trail packing a 9mm semi-auto pistol. The bad guy jumps in the drivers seat but has no keys to start the car. The good guy jumps on the hood and starts unloading while aimed at the bad guys face. He empties the mag into the glass and you hear “click” “click” and he tries to keep firing the empty gun and the bad guy just sits there and laughs. Everything goes quiet for a moment as the last of the brass tinks around on the concrete. Then the good guy throws open his overcoat to reveal a dozen or so more mags stowed in pockets. After some pretty dramatic mag changes and a million different camera angles, he finally drills the bad guy in the face….que blood splatter and brain chunk sprayage. Moral of the story? BP glass failure positively correlates with number of rounds fired into it.
The movie was The Man From Nowhere, a Korean action film.
So uhmmm… let this be a lesson to everyone. Next time you decide to run head first through the glass in the drive through at the bank, to give the sexy teller a kiss, your head is going to bounce off the glass at least 164 times before you get in. Provided you have a little bitty head, and run into the glass really really hard.
It amazes me how people will judge other peoples activities as waste.. Are you paying his bills? is he living in your home ? My guess to both answers is no.. It is his time his money his equipment and his life to do with want he wants..This is the problem with people the wont mind their business . Shows a few posters are lacking common sense..
I guessed 50 so I was pretty close! Maybe he should have gotten a little closer to the target as this would have made the grouping a little bit tighter and probably would have used less than 64 rounds to get through the glass.
There is No shortage of .22 ammo here in North Alabama…
Who comes up with this BS and who cares?
I wouldn’t have used Velociter. I’d have used a solid-nosed bullet. I suspect if you try it again using solid-nosed fodder, your results will be much better.
And for what it’s worth, I’ve never had good results with those .22LR drum magazines.
How about trying 12 GA Winchester BRI deer slugs on your glass.
I agree with ‘waste of precious 22LRs’ that “What I Know” wrote. Damned hard to come by still unless you have family member or close friend with an FFL that deals in ammo. One of them can specifically set aside/order some for you. I figured 40-50 rounds to punch through a by a small group until the shooter mentioned that he had zero magnification on the Red Dot. I then doubled the numbers due to not being able to hammer a very small area, repeatedly. Took less than I figured once he kept them in an 1 1/2″ area.
I don’t believe there is a driver of a vehicles that are thus equipped with the “bullet proof” glass that is going to set there and let anyone hammer away, no matter what the glass is made from or armored with. Thus WHY waste the ammo? I reckon he had a point to prove or a bet to win?
WHY
What a hell of a wast of 22 ammo.
22 ammo is had to come by.
And as always Smith & Wesson Arms are not working or shooting right!!
Why do people own or even, like them.
Thank You.
And no answer if you can’t view the video, how thoughtful.
64 Velocitor rounds!
Next time, try full metal jacketed 30:06 ball ammo. One.
More than 1.
It would be helpful to use solid ammo. Why would one select a bullet that fragments tp penetrate bullet proof glass? It would take less than half as many CCI mini mag solid ammo.
