Description
Fiocchi’s Range Dynamics line is built around one straightforward purpose: giving shooters a reliable, consistent round they can run through a high-volume training session without second-guessing every shot. This 5.7x28mm load is engineered specifically for the modern pistol platforms chambered in that cartridge, where feed geometry and pressure consistency matter more than they do in a more forgiving caliber. A full metal jacket profile feeds smoothly through semi-automatic actions and leaves the bore without the fouling that softer projectile designs can accumulate during extended range work.
The 40-grain bullet leaves the muzzle at 1,700 feet per second, which in the 5.7x28mm context means a flat trajectory that lets you build fundamentals at distance without compensating for significant drop at typical handgun ranges. That velocity also keeps the round within the performance envelope that the platforms chambered for this cartridge were optimized around, so you are replicating your defensive or duty load’s handling characteristics while keeping cost per round down. Recoil is light and consistent, which matters when you are working through 150 rounds in a single session — fatigue and flinch develop quickly when round-to-round variation is high, and this load is loaded to dependable, repeatable specifications. Brass cases are reloadable for those who want to reclaim the brass. Each box contains 150 rounds, and the 450-round case option gives frequent 5.7 shooters a straightforward way to stock training ammunition without repeated small purchases.
