Description

Product Overview

Engineered for consistent performance and reliable function, the Fiocchi Range Dynamics Brass 5.7x28mm 40 Grain FMJ Bulk Pack is a purpose-built training and range ammunition solution. This 150-round pack provides shooters with a cost-effective means to maintain proficiency with firearms chambered in this modern, high-velocity caliber. It is ideally suited for owners of platforms like the FN Five-seveN, PSA Rock, Ruger-57, and the innovative F1 Firearms FDR-15 upper receiver assemblies configured for 5.7×28. The primary use for this ammunition is high-volume range training, target practice, and familiarization, allowing shooters to experience the unique handling characteristics of the 5.7×28 round without depleting more expensive defensive loads.

Key Features

• 150-Round Bulk Pack: Offers a substantial quantity for extended range sessions, reducing the frequency of purchases and providing better value per round compared to standard 50-round boxes.
• 40 Grain Full Metal Jacket (FMJ): Features a lead core fully encased in a copper alloy jacket. This design promotes reliable feeding, minimizes barrel lead fouling, and is intended for target shooting on paper or steel.
• Consistent Range Dynamics Specification: Fiocchi’s Range Dynamics line is formulated to deliver dependable ignition and consistent pressures, shot after shot, which is crucial for developing and maintaining shooter skill.
• Reloadable Brass Casing: Each round is loaded into a high-quality, Boxer-primed brass case. For the handloader, this provides a durable, reusable component that can be reloaded multiple times with proper inspection and procedures.
• Optimized for 5.7×28 Ballistics: The 40-grain projectile weight is balanced to replicate the feel and point of impact of common defensive loads in this caliber, making it an excellent training counterpart.
• Modern Caliber Solution: Addresses the growing demand for affordable practice ammunition in the 5.7×28 space, a caliber renowned for its low recoil, flat trajectory, and high magazine capacity.

Performance & Applications

The specific design parameters of this Fiocchi load make it ideal for several practical shooting applications. First and foremost, it serves as dedicated training ammunition. The low recoil impulse of the 5.7×28 cartridge, replicated here, allows for faster follow-up shots and reduced shooter fatigue during extended practice. This enables focused work on fundamentals like sight alignment, trigger control, and rapid magazine changes.

Secondly, it is excellent for function testing and break-in. When you acquire a new 5.7×28 platform, such as an FDR-15 upper from our team in Spring, TX, running several hundred rounds of reliable FMJ like this Fiocchi offering is a standard process to ensure the firearm cycles smoothly and to acclimate the moving parts before moving on to other ammunition types.

Finally, this ammunition is perfectly suited for action shooting sports like USPSA or Steel Challenge, where the caliber is allowed. Its flat shooting characteristics and minimal muzzle rise can be a competitive advantage in timed events that require engaging multiple targets quickly and accurately.
