AR-15 vs. Backpack. Is it bulletproof?
This video tests the ballistic resistance of a backpack filled with books against various common firearm calibers. The presenter demonstrates that while books can stop some handgun rounds like 9mm, they are less effective against rifle rounds such as 5.56 NATO and 7.62x39mm, and even a .308 Winchester round penetrates a significant amount of book material. The video emphasizes that relying on a backpack or books for ballistic protection is unreliable and strongly advises against it, promoting the 'Run, Hide, Fight' mantra for active shooter situations.
