This video tests the ballistic penetration of a reinforced cinderblock wall against various calibers, culminating in a .50 BMG sniper rifle. The wall, filled with Quikrete, successfully stopped handgun rounds (.22 LR to .44 Magnum) and intermediate rifle rounds (5.56mm, .308), with the 5.56mm penetrating about 3 inches. However, the .50 BMG round completely penetrated the wall, hitting the target dummy.
This video tests the penetration power of various firearms against a large block of Lego baseplates, culminating with a .50 caliber sniper rifle. Results show a clear correlation between caliber and velocity with penetration depth, with the .50 BMG completely overwhelming the Lego structure. The experiment highlights how different ammunition types perform against a non-standard barrier.
This video tests the ballistic penetration of various calibers through paper, culminating in a .50 BMG sniper rifle. Surprisingly, the .44 Magnum penetrated fewer sheets than the 9mm. The .223 caliber AR-15 round demonstrated significant penetration, stopping at 2,166 sheets, while the .50 BMG required 3,187 sheets to stop.
This video tests if a concrete highway barrier can stop a .50 caliber sniper rifle. After testing various suppressed calibers from 9mm up to .460 S&W Magnum, which caused significant damage but no penetration, the .50 caliber rifle was used. Three .50 caliber rounds were required to finally penetrate the 10-inch thick barrier, demonstrating its formidable stopping power against hardened structures.
This video conducts a rigorous durability test on WWII helmets from Japan, America, and Germany. The German Stahlhelm demonstrated superior performance against ballistic threats (.22 LR, 9mm, .45 ACP) and archery, though all helmets sustained damage. Explosive and impact tests revealed varying resilience, with the Japanese helmet showing surprising resistance to blunt force. Ultimately, the German helmet offered the best protection against projectiles.
