I suspect that panel is made out of Lexan, at least the outside layer. Bullet resistant panels are made of layers “glued” together, and they gain their useful properties because the impact energy is used up defeating each layer’s structure and the adhesion. The bubbles you see growing is the adhesive giving way on the outer layer. You may be right about it being “backwards” and I look forward to part two!
Hey PJ , yes it is definitely bonded . It looks like there are 3 glass panels sandwiched between what looks like polycarbonate or lexan . Although the “back and front “ look identical maybe there is still a difference 🤷♂️ we will see 😉
@@Airbuks I bet if you picked the lead out and started shooting through the same hole, you would eventually chew your way through. I think in that one spot the lead is actually deforming and spreading out rather than transferring energy into the next pane of glass.
Would have been better shooting random spots instead of trying to group. I know you said you’re not trying to group but clearly you were. It would be nice to know if that glass is weaker with different areas being shot
Really found your video interesting because No One in airgunning has done this before! While you used the term bullet proof glass, I'm familiar with it as BR glass... meaning Bullet Resistant glass. Either way I found it interesting to watch, so thank you for putting it together and sharing. There has to be a scientific explanation of the spreading pattern? Perhaps something to do with a chemical process formulated to displace heat while absorbing the impact of a projectile. Hope you have a great time at RMAC!
Something different, good video and very interesting! Good luck at rmac! Are those zan premium pellets sorted for size and weight? Have you found them to be more accurate than the jsb 44’s or 50’s?
Yes they are the new BR100 pellets from ZAN. I have done just a little testing and they do seem to work a little better then the JSB ones , so if you shoot competition they give a slight edge and save time in sorting 😉
Make a video and see how many shots with the 30 cal impact it takes to go through the bullet proof glass, cool results and good luck at the competition 👍👍👍👍👍
@Airbuks you're just gonna need a shit load of pellets and alot of air, it would be cool to see it and you'd be the first person to ever do it, get er done airbuks👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
04-23-2023 12:53 a.m. (my time)(Sunday morning). This is what I would be interested in seeing you test, using .30 cal. hollow point slugs (as heavy as possible), glue steel bearings (slightly smaller than the .30 cal. obviously), at max power on the rifle and shoot around the sticker to prevent the slugs from stacking on each other. Do the same thing again using copper coated pellets, make sure to keep them from stacking on each other, see how this perform versus the steel bearings. Use the rifle that will give you the most speed & power. I hope that you see this comment before you do the 2nd round of testing on that bullet proof glass. And yes, please use safety glasses. Thanks for sharing.
Acril glas laag. Meest transparant, warmt op bij wrijving en vertraagd projectiel. De lagen er achter zijn meestal triple gelaagd getemperd glas. Hoe ze het precies doen is wss aan Saint gobain om het uit te leggen
Het is interessant om de resultaten te zien , had het eerlijk gezegd niet verwacht 😉 de slugs gaan wel door de acril maar zelfs het getemperd glas barst niet 😉 misschien maar goed ook dat een buks niet veel kan doen anders zou het niet echt zijn naam BPG waard zijn 🤣
Thanks for the video. Great work. Must have taken a lot of time to make.. Shooting it from the other side ? I think (70/30) the pellet will be stuck in the same depth. Anyways. If the pellets did not exspand (where made of steel)..The .22.. 34 Grains. 1000fps. Would have the best potential for penetration..34G at 1000 FPS is 102 J.. Front area is 23,75 mm2..A .30 pellet has a front area of 45,6 mm2..So a .22 at 102 J has the same J/mm2 as a .30 at 196 J.. A "small" .357 Magnum handgun has between 550-800 J. Front is 64,5 mm2..Or the same J/mm2 as a .22 at 203- 295 J..
While shaking m3 up down does it make sound, mine does is there any fault, sound comes from the valve/hammer area,like something is sliding back and forward,
I am wondering if the other side is the same polycarbonate or actually glass . Before I shot it there was no noticeable difference between the two sides 🤷♂️
@@kevintravis2154 🤔 maybe the two outside layers but I can see a crack on one of the layers inside/in between? ( the reason why I was able to get it 😉)
