Ballistic Gel Test: 300Blk 7.5” 1:5 Twist

Published on January 27, 2025
Duration: 17:46

This video conducts a ballistic gel test of various 300 Blackout subsonic ammunition loads fired from a 7.5-inch barrel with a 1:5 twist rate. The presenter, Justin from Cerebral Farms, evaluates penetration, expansion, and cavity formation for rounds from Phantom Defense (110gr Rowdy Boy, 85gr Spicy Boy, 220gr Big Brother), Hornady, Nautilus, and Veo. The testing aims to determine the most effective subsonic round for home defense, with a surprising conclusion favoring lighter, faster projectiles.

Quick Summary

The 85-grain Phantom Defense Spicy Boy subsonic 300 Blackout round demonstrated superior terminal performance in ballistic gel tests, effectively dumping energy and creating a significant cavity. This led the presenter to select it as his preferred home defense round over heavier 220-grain options.

Frequently Asked Questions

What 300 Blackout subsonic ammunition performed best in the ballistic gel test?

In this ballistic gel test using a 7.5-inch barrel with a 1:5 twist, the 85-grain Phantom Defense Spicy Boy subsonic 300 Blackout round demonstrated superior terminal performance by dumping energy effectively and creating a significant cavity. Heavier 220-grain rounds penetrated deeper but showed less dramatic expansion.

How did heavier 220-grain 300 Blackout subsonic rounds perform in ballistic gel?

The 220-grain subsonic 300 Blackout rounds, such as the Phantom Defense Big Brother and Nautilus, penetrated deeper into the ballistic gel compared to lighter options. However, they exhibited less significant expansion and energy dump, leading the presenter to question their effectiveness for home defense in this specific test scenario.

What barrel specifications were used for the 300 Blackout ballistic gel test?

The ballistic gel tests were conducted using a 7.5-inch barrel with a 1:5 twist rate. The presenter specifically noted the 1:5 twist rate as a primary reason for choosing this particular barrel for the 300 Blackout platform.

Which 300 Blackout subsonic round did the presenter choose for home defense after the test?

After conducting the ballistic gel tests, the presenter concluded that the 85-grain Phantom Defense Spicy Boy subsonic 300 Blackout round was the most effective for home defense due to its impressive terminal ballistics and energy transfer within the gel medium.
