This video tests the ballistic resistance of a commercial 'quebra-queixo' (likely a type of barrier or target material) against various calibers. It demonstrates how different ammunition types, from .22 LR to 6.5 Creedmoor, impact and damage the material, providing a visual assessment of penetration and structural integrity. The testing highlights the significant destructive power of higher calibers like 7.62x39mm and 6.5 Creedmoor.

Quick Summary

A ballistic test evaluated a commercial 'quebra-queixo' material's resistance to various calibers. While .22 LR left marks without penetration, .380 ACP removed a third of the material. 9mm fractured it extensively, and 7.62x39mm and 6.5 Creedmoor rounds completely destroyed the material.
