This video from Kentucky Ballistics showcases an extreme ballistic test comparing a 4 Bore rifle against a bulletproof mask. The test demonstrates the immense power of the 4 Bore, which significantly damages both the mask and a ballistic dummy, highlighting that even advanced protective gear may not withstand such extreme forces. The expert analysis includes projectile recovery and examination of impact damage.

Quick Summary

The 4 Bore round impacted a bulletproof mask with immense force, causing severe deformation and penetration. The mask was punched through, and the ballistic dummy's head sustained critical damage, demonstrating that such extreme calibers can overwhelm standard protective gear and likely result in fatal trauma.

Frequently Asked Questions

What happened when a 4 Bore round hit a bulletproof mask?

The 4 Bore round caused immense damage, severely deforming the bulletproof mask and shattering parts of the ballistic dummy's head structure. The mask was punched through in the nose area, indicating it did not prevent fatal trauma.

Can a bulletproof mask stop a 4 Bore rifle round?

Based on this test, a standard bulletproof mask, even against a powerful rifle like the 4 Bore, is unlikely to prevent fatal trauma. The impact caused significant penetration and structural damage to both the mask and the underlying ballistic dummy.

What kind of damage did the 4 Bore projectile sustain?

The recovered 4 Bore lead projectile showed clear imprints from the ballistic mask's fibers on its surface. This indicates the force of impact and the interaction between the projectile and the protective material.

What is a 4 Bore rifle?

A 4 Bore is an extremely large caliber firearm, historically used for hunting dangerous game or as artillery. It fires a massive projectile with significant kinetic energy and stopping power, far exceeding typical hunting or self-defense calibers.
