Description
The 5.56 55GR FMJ Match Grade projectile delivers the accuracy and consistency serious shooters demand without the premium price tag of boutique competitors. Built on a foundation of precision manufacturing, each bullet features a CDA 220 gilding metal jacket, the industry-standard 90/10 copper-zinc alloy proven to reduce barrel fouling while maintaining exceptional concentricity and uniform jacket thickness. At 55 grains, this projectile sits at the optimal weight-to-velocity sweet spot for the 5.56 NATO cartridge, delivering flat trajectories and predictable flight characteristics across standard barrel twist rates (1:7 to 1:9). The full metal jacket design ensures reliable feeding in semi-automatic and select-fire platforms while providing the consistent bullet-to-bullet weight tolerances that precision handloaders require.

Product Details
Why Choose Rock Manufacturing Match Grade?
Unlike mass-produced pulled or surplus projectiles, our 55GR FMJ bullets are manufactured to exacting dimensional standards with tight lot-to-lot consistency. The result is ammunition that groups tighter, shoots cleaner, and delivers the kind of repeatable performance that lets you focus on fundamentals rather than fighting your equipment.
Whether you're loading for competition, building inventory for high-round-count training courses, or supplying ammunition for professional applications, these projectiles provide the quality-to-value ratio that keeps you shooting more for less.

Precision That Performs, Round After Round
Every shot tells a story. With Rock Manufacturing 5.56 55GR FMJ Match Grade projectiles, that story is one of consistency, reliability, and precision engineering at a price that respects your training budget.
The Gilding Metal Advantage
Our CDA 220 jacket isn't just a material choice—it's a performance decision. This 90/10 copper-zinc alloy has been the gold standard in military and match ammunition for decades because it works:
Reduced Fouling: Cleaner barrels mean more rounds between maintenance and tighter groups throughout extended shooting sessions
Consistent Expansion Characteristics: Uniform jacket thickness ensures predictable terminal performance
Barrel-Friendly Composition: Softer than pure copper jackets, reducing throat erosion in high-volume applications

Built for the Modern Shooter
From the AR-15 enthusiast building precision handloads to the ammunition manufacturer scaling production, these projectiles answer the call:
For Competitive Shooters: Lot-to-lot consistency means your zero stays your zero. Spend less time chasing adjustments and more time dropping targets.
For High-Volume Trainers: When round counts matter, you need components that deliver without compromises. Our FMJ design feeds reliably in everything from bone-stock carbines to race-tuned competition builds.

Quality You Can Measure
Every production run undergoes statistical process control for weight variance, concentricity, and dimensional compliance. We don't ship seconds. We don't blend lots. What leaves our facility is match-grade period.
