If you run a lot of rounds downrange at the range or in practice sessions, Fiocchi Range Dynamics 223 Rem 55gr FMJBT ammo delivers the consistency and value competitive shooters and high-volume practitioners demand. Loaded in the USA with quality powders and components, these 55-grain full metal jacket rounds are built to cycle reliably through your .223 rifle while keeping your cost-per-round reasonable—important when you're burning through case after case perfecting your fundamentals or breaking in a new rifle.

The 55-grain FMJBT (full metal jacket boat tail) profile is a proven load for .223 shooters. With a muzzle velocity of 3,240 fps and muzzle energy of 1,282 ft-lbs, you're getting a straightforward, predictable round that performs consistently shot to shot. That repeatability matters when you're trying to diagnose your technique or dial in a new optic setup. Whether you're working on accuracy at 100 yards or ringing steel at distance, these rounds give you the dependable platform you need without the premium price tag.

Fiocchi has been making ammunition for over 150 years, and their USA-loaded Shooting Dynamics line reflects that manufacturing heritage. This 50-round box format lets you grab exactly what you need for a session without committing to a full case, though if you're a serious practice shooter, ordering by the case (20 boxes per case) makes economical sense.

Frequently Asked Questions

Is Fiocchi Range Dynamics 223 ammo reliable in AR-15 rifles?

Yes. The 55-grain FMJBT load is a standard .223 Rem cartridge that functions reliably in AR-platform rifles and traditional bolt-action .223 rifles alike. The full metal jacket design feeds consistently through magazine-fed systems.

What's the difference between a 55-grain and heavier .223 loads?

The 55-grain is the original .223 Rem ballistic standard—lighter and faster than heavier options. It's ideal for target shooting and practice where you value lower recoil and higher velocity. Heavier bullets (62, 69, 77 grains) offer better wind deflection and energy retention at distance but come with slightly more recoil.

How many boxes come in a case?

Each case contains 20 boxes of 50 rounds, for a total of 1,000 rounds per case.

Is this ammunition suitable for hunting?

These rounds are designed and marketed for range practice and target shooting. For hunting applications, consult local regulations and consider ammunition specifically loaded for that purpose.
