This expert-level review by TFB TV details a ballistic gel test of Hornady's 190gr Sub-X .300 AAC Blackout subsonic ammunition. The test, conducted with an 8-inch SBR, analyzes expansion and penetration through bare gel and heavy clothing. The instructor concludes that subsonic .300 BLK is generally less effective for self-defense than supersonic loads.

Quick Summary

The Hornady 190gr Sub-X .300 Blackout subsonic ammunition achieved 17.2 inches of penetration in bare ballistic gel, with modest expansion up to 0.767 inches. When fired through heavy clothing, penetration increased to 20.8 inches with slightly reduced expansion. The average velocity was 989 FPS.

What were the results of the Hornady 190gr Sub-X .300 Blackout subsonic ammunition in bare ballistic gel?

In bare 10% ballistic gelatin, the Hornady 190gr Sub-X .300 Blackout began expanding at 1 inch, with one fragment breaking off early. It achieved a penetration of 17.2 inches with modest expansion, reaching a maximum diameter of 0.767 inches.

How did the Hornady 190gr Sub-X .300 Blackout perform when fired through heavy clothing?

When fired through four layers of denim, the Hornady 190gr Sub-X .300 Blackout showed similar performance to bare gel. Penetration ranged from 20.3 to 20.8 inches, with slightly reduced expansion compared to the bare gel test, reaching a maximum of 0.483 inches.

Is subsonic .300 Blackout recommended for self-defense according to the TFB TV instructor?

No, the instructor argues that subsonic .300 Blackout is a poor choice for self-defense compared to supersonic rifle loads. He describes it as essentially a pistol cartridge, lacking the terminal ballistics of full-power rifle rounds.

What was the average velocity of the Hornady 190gr Sub-X .300 Blackout tested?

The average velocity recorded for the Hornady 190gr Sub-X .300 Blackout ammunition during the test was 989 FPS. This is well below the speed of sound, confirming its subsonic performance characteristics.
