This video demonstrates the terminal ballistics of various handgun calibers after passing through a car windshield, using 10% ballistic gel. The presenter tests 9mm, .40 S&W, .45 ACP, 10mm, .44 Magnum, and .500 Magnum, analyzing bullet expansion, penetration, and fragmentation. The results highlight how windshield penetration can affect bullet performance, with some calibers showing significant degradation while others remain highly effective.

Quick Summary

Car windshields can significantly impact handgun bullet performance, often reducing velocity and hindering hollow point expansion. Tests show that while smaller calibers like 9mm may show reduced effectiveness, larger calibers like .44 Magnum and .500 Magnum retain substantial terminal ballistics after penetration.

Frequently Asked Questions

How does a car windshield affect handgun bullet performance?

A car windshield can significantly alter handgun bullet performance by causing fragmentation, reducing velocity, and potentially preventing hollow point expansion. Some calibers show less degradation than others, with larger calibers generally retaining more effectiveness.

Which handgun calibers were tested against a car windshield?

The test included 9mm, .40 S&W, .45 ACP, 10mm, .44 Magnum, and .500 Magnum. Each caliber's terminal ballistics were evaluated after passing through the windshield into ballistic gel.

Did hollow point bullets expand after going through a car windshield?

In some cases, hollow point bullets did not expand as expected after passing through the windshield. This could be due to reduced velocity or the hollow point cavity clogging with glass, effectively turning the bullet into a full metal jacket.

What was the penetration depth of different calibers through a car windshield and ballistic gel?

Penetration varied by caliber. The 9mm penetrated about 10 inches, the .40 S&W about 13 inches, while the .45 ACP, 10mm, .44 Magnum, and .500 Magnum all penetrated the full 16-inch gel block, with the larger calibers showing more significant wound cavities.
