Duration: 7:59

This expert-level analysis from TFB TV details the terminal performance of Hornady 190gr Sub-X .300 AAC Blackout subsonic ammunition through ballistic gelatin. The test, conducted by an authoritative instructor, highlights expansion characteristics, penetration depths, and retained projectile weights under various conditions, including heavy clothing barriers. The assessment concludes with a critical comparison of subsonic versus supersonic .300 Blackout for self-defense applications.

Quick Summary

Expert analysis of Hornady 190gr Sub-X .300 Blackout subsonic ammunition reveals an average velocity of 989 FPS from an 8-inch barrel. In bare gel, it expanded to 0.767" and penetrated 17.2". Through heavy clothing, expansion was reduced but penetration was maintained. Subsonic .300 BLK is generally not recommended for self-defense over supersonic loads.

Frequently Asked Questions

What is the terminal performance of Hornady 190gr Sub-X .300 Blackout subsonic ammunition?

In bare ballistic gelatin, the Hornady 190gr Sub-X .300 Blackout achieved an average velocity of 989 FPS, expanded up to 0.767 inches, and penetrated 17.2 inches. Through heavy clothing, expansion was slightly reduced but penetration remained robust.

Is subsonic .300 Blackout suitable for self-defense?

According to expert analysis, subsonic .300 Blackout is generally considered a poor choice for self-defense compared to supersonic rifle loads. While it offers reduced noise and recoil, its terminal ballistics and energy transfer are significantly less effective.

What are the key specifications of the Hornady 190gr Sub-X .300 Blackout tested?

The tested ammunition featured a 190-grain Sub-X bullet with FlexTip technology, fired from an 8-inch barrel with a 1:7 twist rate, achieving an average velocity of 989 FPS.

How does Hornady's Sub-X bullet expand?

The Sub-X bullet is designed to expand reliably at subsonic velocities, initiating expansion around 1 inch into media. Its FlexTip aids in expansion, even after passing through barriers like heavy clothing.
