Is Your Home Defense Gun Too Powerful???

Duration: 13:09

This video tests the overpenetration capabilities of various common self-defense calibers and firearms through concrete blocks, simulating a fortified home defense scenario. The presenter demonstrates how 9mm and .45 ACP handguns, 5.56x45mm, 7.62x39mm, .308 Winchester, .45-70 Government, and 12 gauge shotgun loads (birdshot, buckshot, slug) perform against concrete. The findings suggest that concrete walls offer significant resistance, stopping most handgun rounds and fragmenting rifle rounds, though more powerful calibers like .308 and 7.62x39mm showed potential for partial penetration.

Quick Summary

Testing shows that concrete walls offer substantial protection against home defense firearms. 9mm and .45 ACP rounds did not penetrate concrete, while 5.56x45mm fragmented. More powerful rounds like .308 Winchester showed a higher likelihood of penetration, and 12 gauge birdshot was ineffective against the material.

Frequently Asked Questions

Do common handgun calibers like 9mm and .45 ACP overpenetrate concrete walls?

Based on testing with concrete blocks, 9mm and .45 ACP rounds using hollow-point ammunition did not penetrate the concrete. This suggests that in a home with concrete walls, these handgun calibers are unlikely to pose a significant overpenetration risk to bystanders.

How does the 5.56x45mm round from an AR-15 perform against concrete walls?

The 5.56x45mm round from an AR-15 was observed to destroy the concrete block it impacted. However, the bullet fragmented upon impact, and no complete penetration was observed, indicating it is less likely to overpenetrate concrete than some other rifle rounds.

What is the overpenetration risk of a .308 Winchester rifle round through concrete?

The .308 Winchester round demonstrated significant destructive power against concrete, and evidence suggests it likely passed through the concrete block. This indicates a higher potential for overpenetration with this caliber compared to handguns or smaller rifle rounds in a concrete structure.

Does 12 gauge birdshot penetrate concrete?

No, 12 gauge birdshot showed no significant penetration of the concrete block, only causing minor surface dents. While this confirms it won't overpenetrate, it also highlights its ineffectiveness for stopping threats through such a barrier.
