The Hornady .22 Caliber (.224") 55 Grain FMJ-BT with Cannelure (part number 22672) is an inert, non-expanding component projectile engineered for high-volume rifle cartridge reloading. Manufactured with Hornady’s Advanced Manufacturing Process (AMP) copper jacket over a lead core, this bullet delivers near-zero wall thickness variation to eliminate concentricity flaws. Designed primarily for .223 Remington and 5.56×45mm NATO handloads, it features a boat tail base to ease case neck seating and reduce aerodynamic drag, alongside an integrated cannelure for secure roll or taper crimping. It stabilises across common rifle barrel rifling twist rates, from legacy 1:12" and 1:14" profiles to modern 1:9", 1:8", and 1:7" setups.

• AMP Jacket Construction: Engineered with an Advanced Manufacturing Process copper jacket to maintain uniform wall thickness and concentricity across high-volume production batches.
• Boat Tail Base Profile: Reduces aerodynamic drag in flight while streamlining bullet alignment during the handloading seating stroke.
• Integrated Cannelure: Accommodates uniform mechanical crimping to prevent bullet setback under recoil or semi-automatic feeding cycles.
• Versatile Barrel Compatibility: Stabilises reliably across standard .224-bore barrel twist rates ranging from 1:7" through 1:14".

Who is the Hornady 55 Grain FMJ-BT 1,000 Pack for?

• High-volume .223 Remington and 5.56×45mm NATO reloaders — seeking cost-efficient component manufacturing through a 1000-count bulk pack of standard 55 grain .224 reloading bullets suited for repetitive target handloading.
• Service rifle and tactical training practitioners — requiring consistent short-to-intermediate range trajectories, supported by an aerodynamic profile offering a 0.243 G1 ballistic coefficient and a 0.157 sectional density across distances out to 300 metres.

Less suitable for: Target engagements beyond 300 to 400 metres where wind drift demands heavier 68 to 77 grain match projectiles with higher ballistic coefficients, or game hunting applications where non-expanding FMJ bullets must be replaced by expanding soft-point or ballistic-tipped hunting bullets to ensure ethical terminal performance.
