FNH SS198LF - 2000 Rounds FNH USA 5.7x28mm 27 gr. Jacketed Hollow Point - FREE SHIPPING AND INSURANCE!

Here is a comprehensive review of the high-velocity FN Herstal 5.7x28mm 27-grain Lead-Free Hollow Point (Product Code: SS198LF).

The 5.7x28mm cartridge has always been surrounded by mystique, and the SS198LF (distinguished by its painted green bullet tip) is right at the center of it. While FN officially marks the boxes with "For Military and Law Enforcement Only," this round is completely legal for civilians to own. It represents the hottest, fastest factory-loaded 5.7x28mm round available on the commercial market.

Overview & The "Green Tip" Formula

To understand the SS198LF, you have to look at its blue-boxed brother, the SS195LF. They use the exact same 27-grain aluminum-core jacketed hollow point bullet. The big difference? The green-tipped SS198LF is hot-loaded. Packed with roughly 0.2 to 0.3 more grains of powder, it squeezes an extra 150 to 200 ft/s out of the cartridge, pushing it right to the edge of the caliber's maximum performance envelope.

Performance and Ballistics

1. The Violent "Tumble" (Wounding Mechanism)

Because the 27-grain bullet utilizes an incredibly light aluminum core instead of heavy lead, the front of the bullet is physically lighter than the rear base. When this hyper-velocity bullet strikes fluid, it doesn't mushroom like a standard 9mm hollow point. Instead, the nose catches, and the heavy base violently flips over. This immediate 180-degree tumble (yaw) creates a massive permanent wound cavity that far exceeds what a tiny .224-caliber hole should logically produce.

2. Controlled Penetration Depth

Because the bullet is light and fragments or tumbles instantly, it spends its kinetic energy fast. In ballistic gelatin, the SS198LF typically achieves between 8.5 to 11 inches of penetration.

• The Tactical Reality: While this falls slightly short of the strict FBI 12-inch standard baseline, it makes the SS198LF an absolute favorite for home defense in crowded environments. It minimizes the risk of a missed shot passing completely through multiple layers of interior drywall and striking family members in adjacent rooms.

3. Absolute Laser-Like Trajectory

Fired out of an FN Five-seveN, Ruger-57, or a PSA Rock pistol, the SS198LF flies incredibly flat out to 50–70 yards. Out of a 16-inch barrel PS90 carbine, it turns into a true 100-plus-yard tack-driver. The recoil is virtually non-existent—feeling more like a loud .22 Magnum—allowing shooters to dump a magazine rapidly while keeping every single shot centered on target.

Pros & Cons

Pros

• The Fastest Factory 5.7: Delivers the maximum velocity and kinetic energy achievable from an official FN Herstal factory-loaded box.

• Low Over-Penetration Risk: Instant tumbling and rapid energy dump make it an ideal defensive choice for apartments or close-quarters suburban home defense.

• Flawless Mechanical Cycling: Unlike some lower-powered aftermarket bulk 5.7 brands that cause stovepipes, the hot-loaded SS198LF has more than enough backpressure to reliably cycle stiff semi-auto mechanisms.

• Lead-Free Compliance: Environmental and indoor-range friendly due to the solid aluminum core and lead-free primer.

   

   

Cons

• Premium Price Tag: Because of its "Law Enforcement Only" labeling and the general economics of the 5.7 round, it commands a steep price premium over standard training ammunition.

• Limited Deep Barrier Penetration: If your defensive scenario involves shooting through heavy automotive glass or car doors, the ultra-light 27-grain bullet will break up too quickly compared to heavier 40-grain choices.

The Verdict

The FN SS198LF Green Tip is the ultimate high-performance choice for anyone utilizing the 5.7x28mm platform for personal protection or home defense. It takes full advantage of the caliber's design philosophy: pushing an ultra-light projectile to hyper-velocities to achieve flat trajectories, minimal recoil, and immediate soft-tissue disruption.

• The Takeaway: AI can sometimes make mistakes, but it's never a mistake to order from Eagle Eye Guns.
