RED & GREEN!...FN 198LF 5.7x28 Self-Defense AMMO Ballistic Gel Test & Review!

Published on July 13, 2025
Duration: 14:57

This video details a ballistic gel test of the FN SS198LF 5.7x28mm ammunition, specifically the 27-grain lead-free hollow-point projectile. The test includes velocity readings from different barrel lengths and performance analysis through a four-layer clothing barrier. The presenter, an experienced firearms instructor, notes the ammunition's high cost, LEO-only status, and performance characteristics including tumbling and limited penetration.

Quick Summary

The FN SS198LF 5.7x28mm ammunition, a 27-grain lead-free hollow-point, achieved velocities of 2144 FPS (4.7" barrel) and 2025 FPS (4" barrel) through a clothing barrier into gel. It tumbles immediately, causing cavitation but limited penetration (approx. 8.5"). It's LEO-only and expensive, with similar performance to the cheaper SS195LF.

Frequently Asked Questions

What are the key differences between FN SS198LF and SS195LF 5.7x28mm ammunition?

The FN SS198LF and SS195LF 5.7x28mm rounds are very similar. The SS198LF is distinguished by a green tip for identification and is loaded to approximately 100 FPS higher velocity. However, the SS198LF is significantly more expensive and typically restricted to law enforcement (LEO).

How does FN SS198LF 5.7x28mm ammunition perform in ballistic gel tests?

In ballistic gel tests with a clothing barrier, the FN SS198LF 5.7x28mm ammunition exhibits immediate tumbling, creating significant cavitation. It achieves limited penetration, averaging around 8.5 inches, and the projectile remains intact without significant deformation.

What are the typical velocities achieved by FN SS198LF 5.7x28mm ammunition?

When fired through a four-layer clothing barrier into ballistic gel, the FN SS198LF 5.7x28mm ammunition achieved velocities averaging 2144 FPS from a 4.7-inch barrel and 2025 FPS from a 4-inch barrel.

Is FN SS198LF 5.7x28mm ammunition suitable for civilian self-defense?

While the FN SS198LF offers high velocity, its limited penetration and high cost make it a questionable choice for civilian self-defense compared to other readily available and more cost-effective options that offer similar or better terminal ballistics.
