Hollow point vs full metal jacket watermelon test

Published on January 7, 2025
Duration: 0:46

This video demonstrates the terminal ballistics difference between hollow point (HP) and full metal jacket (FMJ) ammunition using watermelons as targets. The FMJ round passed through cleanly, while the HP round caused the watermelon to fragment extensively, indicating superior energy transfer. The host recommends HP for self-defense based on this test.

Quick Summary

Hollow point (HP) ammunition is recommended for self-defense because it's designed to expand upon impact, unlike full metal jacket (FMJ) rounds. This expansion increases energy transfer and creates a larger wound channel, leading to more effective stopping power, as visually demonstrated in a watermelon test.

Frequently Asked Questions

What is the difference between hollow point and full metal jacket ammunition?

Full metal jacket (FMJ) bullets have a lead core encased in a harder metal jacket, designed for penetration. Hollow point (HP) bullets have a cavity at the tip, designed to expand upon impact, increasing energy transfer and creating a larger wound channel, making them generally preferred for self-defense.

How does a hollow point bullet perform compared to an FMJ bullet?

In a terminal ballistics test using watermelons, a hollow point bullet caused the target to explode into many pieces, demonstrating significant energy transfer and expansion. A full metal jacket bullet passed through with less dramatic effect, showing less expansion and energy transfer.

Why are hollow points recommended for self-defense?

Hollow points are often recommended for self-defense because their design promotes expansion upon hitting a target. This expansion increases the bullet's diameter, creating a wider wound channel and transferring more energy to the target, which can lead to quicker incapacitation.

Can a watermelon be used to test bullet performance?

Yes, a watermelon can serve as a visual aid to demonstrate bullet performance differences, like expansion and energy transfer, between ammunition types such as hollow point and full metal jacket. It's a readily available alternative to ballistic gelatin for informal testing.
