The Fiocchi Hyperformance Defense 5.7x28mm 40gr Jacketed Polymer ammunition is engineered to meet the demands of self-defense and range proficiency that Tennessee shooters expect from their gear.

What This Product Is and Who It’s For

Fiocchi Hyperformance Defense 5.7x28mm 40gr Jacketed Polymer ammunition is a factory-loaded cartridge designed for defensive use in firearms chambered for the 5.7x28mm caliber. The 40-grain bullet features a jacketed polymer tip that promotes consistent expansion upon impact, while the polymer construction reduces weight and enhances velocity retention. This ammunition is intended for shooters who prioritize personal protection, including concealed carriers, home defense users, and those who train regularly with their 5.7x28mm platforms. It also serves well for target shooters who want a defensive-grade round for practice without switching between loads. Collectors of 5.7x28mm ammunition will appreciate the consistent manufacturing standards Fiocchi brings to this hyperformance line.

Feature Deep-Dive

The Fiocchi Hyperformance Defense 5.7x28mm 40gr Jacketed Polymer ammunition is built around a 40-grain bullet that uses a polymer-tipped hollow point design. The polymer tip serves a dual purpose: it streamlines the bullet’s profile for improved aerodynamic performance during flight, and it initiates controlled expansion upon impact with soft tissue. This expansion creates a larger wound channel while limiting over-penetration, which is a critical consideration for Tennessee homeowners who share walls in apartments or have family members in adjacent rooms. The jacketed construction ensures the bullet retains its structural integrity as it penetrates, reducing the risk of fragmentation that can compromise stopping power.

Fiocchi engineers the Hyperformance Defense line to deliver consistent muzzle velocities across varying barrel lengths, which is especially relevant for 5.7x28mm platforms like the FN Five-seveN pistol or the PS90 carbine. The 40-grain bullet weight is a well-established standard for this caliber, offering a balance between speed and energy transfer. Fiocchi uses a clean-burning propellant that minimizes fouling in the barrel and action, which helps maintain reliability during extended shooting sessions at Tennessee ranges. The brass casings are reloadable for those who handload, though Fiocchi’s factory loads are optimized for defensive use out of the box.

The ammunition is loaded with non-corrosive Boxer primers, which are standard for modern defensive rounds and do not require special cleaning procedures after use. This is a practical advantage for shooters who may not have time for extensive maintenance after a training session or a defensive scenario. Fiocchi’s quality control includes lot testing for velocity and pressure consistency, so each round in the 50-round box performs predictably. The polymer tip also reduces the risk of bullet setback when the cartridge is chambered multiple times, a common concern with hollow point ammunition used for carry.

Terminal performance is a key focus of the Hyperformance Defense line. The 40-grain jacketed polymer bullet is designed to expand to approximately 1.5 times its original diameter in ballistic gelatin, creating a wound profile that balances penetration depth with energy transfer. This makes it suitable for defensive use against human threats while remaining effective against light barriers like heavy clothing or drywall. Fiocchi’s testing indicates that the bullet maintains its trajectory within a 4-inch group at 50 yards from a pistol barrel, which is acceptable for defensive engagements at typical distances.

The packaging itself is practical for Tennessee shooters who buy in bulk or store ammunition for extended periods. The 50-round box uses a sturdy cardboard construction with clear labeling of caliber, bullet weight, and lot number. Fiocchi prints the velocity and energy data on the box for quick reference. The ammunition is sealed in a moisture-resistant inner wrap to protect against humidity, which is useful for those storing rounds in basements or gun safes across Tennessee’s seasonal weather changes. This attention to storage conditions reflects Fiocchi’s understanding that defensive ammunition may sit for months before being needed.

Fiocchi’s Hyperformance Defense line is manufactured in the United States, which means it complies with domestic quality standards and is readily available for shipment to Tennessee addresses. The 40-grain jacketed polymer bullet design is distinct from standard full metal jacket loads because it prioritizes expansion over penetration depth. This makes it a viable choice for shooters who want a single load for both training and carry, as the recoil impulse and point of impact are consistent between practice and defensive scenarios. The 5.7x28mm caliber itself offers low recoil and high magazine capacity, which is advantageous for shooters of all experience levels.

Ideal Use Cases

• Home Defense: The controlled expansion and reduced over-penetration risk make this ammunition suitable for protecting your Tennessee home, especially in multi-story houses or apartments.
• Personal Protection: Carriers in Tennessee can use this load in 5.7x28mm pistols for concealed carry, as the lightweight bullet allows for comfortable carry with high-capacity magazines.
• Range Training: While designed for defense, the consistent trajectory and low recoil make this round practical for regular practice at indoor or outdoor ranges across the state.
• Competition Shooting: Some shooters use 5.7x28mm in action shooting sports, and this ammunition’s accuracy supports such use, though it is not specifically marketed for competition.
