AAC, Why You Do This To .40?....AAC .40 S&W Self-Defense AMMO Ballistic Gel Test!

Published on March 1, 2024
Duration: 11:46

This video details a ballistic gel test of AAC .40 S&W 180-grain XTP ammunition fired from Glock 22 and Glock 27 pistols. The test revealed velocities below the advertised 1,000 ft/s, leading to inconsistent and suboptimal bullet expansion and significant tumbling. The instructor concludes the ammunition performed poorly due to insufficient velocity for the XTP projectile's design.

Quick Summary

AAC .40 S&W 180-grain XTP ammunition averaged 988 ft/s from a Glock 22 and 955 ft/s from a Glock 27, falling short of the advertised 1,000 ft/s. This low velocity resulted in inconsistent performance, with one round showing partial expansion and tumbling, while another failed to expand at all.

Frequently Asked Questions

What were the average velocities for AAC .40 S&W 180gr XTP ammunition tested?

The AAC .40 S&W 180-grain XTP ammunition averaged 988 ft/s from a Glock 22 with a 4.5-inch barrel and 955 ft/s from a Glock 27 with a 3.5-inch barrel. These velocities were below the advertised 1,000 ft/s.

How did the AAC .40 S&W 180gr XTP perform in ballistic gel tests?

Performance was inconsistent. The round from the Glock 22 showed partial expansion and significant tumbling, penetrating 18.5 inches. The round from the Glock 27 failed to expand and penetrated over 32 inches, exiting the gel blocks.

Why did the AAC .40 S&W 180gr XTP ammunition perform poorly?

The primary reason cited is insufficient velocity. The 180-grain XTP projectile requires higher speeds for optimal expansion, and the tested AAC load did not consistently achieve this, leading to tumbling and poor terminal ballistics.

What is the instructor's overall assessment of AAC .40 S&W 180gr XTP ammunition?

The instructor considers the performance poor due to low velocity and inconsistent expansion. They placed this specific ammunition in the 'no good' category, suggesting it is unreliable for self-defense applications.
