Shotgun vs Lamborghini Windshield

Published on August 18, 2017
Duration: 10:59

This guide details a ballistic experiment testing the penetration capabilities of various 12 Gauge shotgun rounds against car windshields at different angles. The experiment, led by Matt Carriker, demonstrates that shallow angles cause birdshot to ricochet, while slugs are more effective for penetration. The results highlight the significant impact of the angle of incidence on terminal ballistics.

Quick Summary

Testing reveals that the angle of impact is crucial for shotgun projectile penetration against car windshields. Birdshot ricochets at shallow angles, while 1oz slugs effectively penetrate. Specialty rounds also struggle with shallow angles, highlighting the importance of projectile design and impact geometry.

Frequently Asked Questions

How does the angle of a car windshield affect shotgun pellet penetration?

At shallow angles, like those found on sports cars, birdshot pellets tend to ricochet off the windshield surface rather than penetrating. Penetration is typically only achieved when the angle of incidence is much steeper, approaching vertical.

What type of shotgun ammunition is most effective for penetrating a car windshield?

Based on the tests, a 1oz low recoil slug demonstrated effective penetration through a windshield even at shallow angles. Birdshot and most specialty rounds were significantly less effective under these conditions.

What is the 'Instant Expansion Round' tested in the video?

The 'Instant Expansion Round' is a specialty 12 Gauge ammunition designed to act like a slug until impact, then disperse its payload. It showed significant energy dispersion, penetrating a dummy's neck but with limited effect behind it.

What are the key takeaways regarding shotgun ballistics and windshields?

The primary takeaway is that the angle of incidence is critical. Shallow angles cause deflection for many projectile types, while slugs offer more reliable penetration. The construction of the safety glass also plays a role.
