Hollow Point vs Car Door High Speed Test | Clogged Hollowpoints Ultra Slo Mo

Published on May 5, 2026
Duration: 1:49

This video demonstrates how hollow point ammunition performance can be significantly degraded when passing through barriers like a car door. It highlights that material buildup within the hollow point cavity can prevent proper expansion, negating its intended effect. The test uses a high-speed camera to visualize bullet behavior after impacting water and a simulated car door.

Quick Summary

Hollow point ammunition is designed to expand upon impact, but passing through barriers like car doors can clog the hollow point cavity with debris. This clogging prevents proper expansion, significantly degrading the bullet's terminal ballistics performance and effectiveness.

Frequently Asked Questions

How does a car door affect hollow point bullet expansion?

Passing through a car door can cause hollow point bullets to become clogged with debris like metal and plastic. This material buildup inside the hollow point cavity prevents the bullet from expanding as intended, significantly reducing its terminal ballistics performance.

What is the purpose of the insert in some hollow point ammunition?

The insert in certain hollow point designs is intended to help initiate expansion, even when the bullet encounters barriers. However, this test suggests that even with inserts, severe clogging from materials like a car door can still impede proper, predictable expansion.

Can hollow points fail to expand after shooting through barriers?

Yes, hollow point bullets can absolutely fail to expand after penetrating barriers. The video demonstrates that materials from a car door can fill the hollow point, preventing it from opening up and mushrooming, which is crucial for its effectiveness.

What is the best way to test bullet expansion through barriers?

A high-speed camera is an effective tool for testing bullet expansion through barriers. It allows for detailed observation of the bullet's behavior immediately after impact, showing whether it expanded, clogged, or deformed in unexpected ways.
