Is This AMMO Any FN Good?...5.7x28 FN DFNS Self-Defense Ballistic Gel Test!

Published on May 4, 2024
Duration: 18:32

This video details a ballistic gel test of FN DFNS 5.7x28mm personal defense ammunition, fired from a PSA 57 Rock pistol and a PS90 carbine. The test focuses on velocity, penetration, and fragmentation characteristics, with the presenter expressing skepticism about the overall effectiveness and consistency of the tested ammunition. The presenter notes significant inconsistencies in cycling and velocity readings, suggesting potential loading issues with this specific batch of ammunition.

Quick Summary

The FN DFNS 5.7x28mm ammunition, tested in ballistic gel, exhibited inconsistent fragmentation, often breaking into large chunks instead of fine powder. Reliability issues, including cycling failures in a PSA 57 Rock pistol, were noted. While velocities met advertised figures, the overall performance and consistency led the presenter to question its effectiveness.

Frequently Asked Questions

What are the key characteristics of the FN DFNS 5.7x28mm ammunition tested?

The FN DFNS 5.7x28mm ammunition is a 30-grain, jacketed hollow point that functions as a frangible round made of powdered copper and tin. It's designed for personal defense and is tested for velocity, penetration, and fragmentation.

What firearms were used to test the FN DFNS 5.7x28mm ammunition?

The ammunition was tested using a PSA 57 Rock pistol with a 4.7-inch barrel and a PS90 carbine with a 16-inch barrel. These were chosen to compare performance against advertised velocities for different firearm types.

What were the main findings regarding the reliability of the FN DFNS 5.7x28mm ammunition?

The testing revealed significant reliability issues, particularly with the PSA 57 Rock pistol, where several rounds failed to cycle properly. This suggests potential inconsistencies in the ammunition's loading or performance characteristics.

How did the FN DFNS 5.7x28mm ammunition perform in ballistic gel?

The ammunition showed inconsistent fragmentation, often breaking into large chunks rather than fine powder as expected from a frangible round. Penetration was around 12-13 inches, and the presenter expressed skepticism about its overall effectiveness.
