Duration: 16:03

This video presents a ballistic gel test of Federal Syntech Defense .40 S&W 175-grain ammunition. The test evaluates projectile performance, fragmentation, and penetration across different barrel lengths (Glock 27 and Glock 22). The instructor notes inconsistency in performance, attributing failures primarily to insufficient velocity, suggesting the nine-millimeter variant might be more reliable.

Quick Summary

Federal Syntech Defense .40 S&W 175-grain ammunition demonstrated inconsistent performance in ballistic gel tests, with failures attributed to insufficient velocity. While claimed to reach 1000 fps from a 4-inch barrel, testing showed average velocities of 957 fps (3.5-inch barrel) and 1007 fps (4.5-inch barrel), leading to poor fragmentation.

Frequently Asked Questions

What is the claimed muzzle velocity for Federal Syntech Defense .40 S&W 175-grain ammunition?

Federal claims a muzzle velocity of 1000 feet per second for their Syntech Defense .40 S&W 175-grain ammunition, typically measured from a 4-inch barrel.

How did the Federal Syntech Defense .40 S&W 175-grain ammunition perform in ballistic gel tests?

The ammunition showed inconsistent performance, with some rounds failing to fragment properly and penetrating deeply without significant expansion. The primary issue identified was insufficient velocity.

What were the average velocities recorded during the ballistic gel test?

From a Glock 27 (approx. 3.5-inch barrel), the average velocity was 957 fps. From a Glock 22 (approx. 4.5-inch barrel), the average velocity was 1007 fps.

What is the main reason cited for the failure of the Federal Syntech Defense .40 S&W ammunition in testing?

The primary reason cited for the failure is insufficient velocity. The ammunition requires more velocity to reliably fragment and perform as designed in ballistic gel tests.
