The BEST 9mm Defensive AMMO Made! Federal HST 124 Standard vs +P Ballistic Gel Test With The P365!

Published on April 8, 2022
Duration: 13:23

This ballistic gel test compares Federal HST 124gr standard pressure and +P 9mm ammunition fired from a Sig P365. The +P variant demonstrated superior performance, achieving higher average velocity (1116 fps vs 1055 fps), deeper penetration (up to 16.375 inches vs 16.25 inches), and slightly greater expansion (up to 0.629 inches vs 0.628 inches). Both loads retained 100% weight, with the +P showing more pronounced petal peeling.

Quick Summary

Federal HST 124gr +P 9mm ammunition averaged 1116 fps from a Sig P365, outperforming the standard load's 1055 fps. The +P achieved slightly deeper penetration (up to 16.375 inches) and marginally larger expansion (up to 0.629 inches), while both retained 100% weight.

Frequently Asked Questions

What were the key performance differences between Federal HST 124gr standard and +P 9mm in the P365 test?

The +P load averaged 1116 fps, 61 fps faster than the standard's 1055 fps. Penetration was slightly deeper for +P (up to 16.375 inches vs 16.25 inches), and expansion was marginally larger (up to 0.629 inches vs 0.628 inches), with both retaining 100% weight.

How did the Federal HST 124gr +P perform in a short-barreled pistol like the Sig P365?

The +P load significantly outperformed the standard pressure version in velocity, penetration, and expansion, demonstrating its effectiveness even from a 3-inch barrel. This suggests +P is a viable option for concealed carry pistols.

What were the expansion and weight retention results for Federal HST 124gr 9mm?

Both standard and +P Federal HST 124gr 9mm bullets retained 100% of their weight (approx. 124.5 grains). Expansion diameters were very similar, ranging from 0.614 to 0.629 inches, with the +P showing slightly more pronounced petal peeling.
