This video tests the ballistic resistance of a prison door against various calibers, culminating in a .50 BMG sniper rifle. While handgun rounds and even the .50 AE Desert Eagle are stopped or partially penetrate, the .50 BMG round easily pierces the door, concrete, and a ballistic dummy. The experiment highlights the significant difference in destructive power between common firearms and heavy-caliber sniper systems.

This video tests the ballistic resistance of standard roofing shingles, evaluating their effectiveness as improvised body armor against various calibers. The content aims to demonstrate what projectiles roofing shingles can and cannot stop. It also promotes "Nine Line Apparel" with a discount code and provides links to the creator's social media, website, and other platforms like the Warrior Poet Society Network.

This video tests the ballistic resistance of traditional Thai red bricks against various firearm calibers. A .22 LR required 2 bricks, while a 9mm penetrated 5. Higher-powered rounds like the .357 Magnum and .308 Winchester broke 7 bricks, demonstrating significant destructive power. The test highlights how brick thickness and ammunition type affect penetration.
