Introduction
Explore the Nosler AccuBond, a bonded-core bullet designed for hunters who demand precision and reliable terminal performance. Introduced by Nosler, Inc. in 2003, based in Bend, Oregon, the AccuBond features a proprietary bonding process that fuses the lead-alloy core to the copper-alloy jacket, ensuring integrity during flight and impact.
Renowned for its high weight retention and controlled expansion, the AccuBond delivers exceptional terminal performance, making it a top choice for ethical hunters targeting big game. Its aerodynamic design excels in long-range scenarios, from open plains to mountainous terrain.
- Caliber Range: Available from .224 to .375 inches, supporting cartridges like .223 Remington, .243 Winchester, 6.5 Creedmoor, .308 Winchester, 30-06 Springfield, and .300 Winchester Magnum.
- Weight Options: Spans 70 to 300 grains, with popular variants like 70-grain .224, 90-grain .243, 140-grain 6.5mm, and 180-grain .308.
- Hunting Focus: Optimized for deep penetration and uniform expansion, ideal for medium to large game like deer, elk, and moose at extended ranges.
Technical Characteristics
The Nosler AccuBond is built for hunters seeking accuracy and durability. Its bonded construction and advanced features ensure superior performance in the field.
- Bonded Core: Lead-alloy core fused to copper-alloy jacket via proprietary process, ensuring 60-70% weight retention with no core-jacket separation, even through bone.
- Polymer-Tipped Design: White polymer tip and hollow-point cavity for controlled expansion at velocities as low as 1,800 fps, achieving 1.5-2x diameter expansion.
- Boat-Tail Profile: Streamlined boat-tail reduces drag for enhanced long-range stability and flat trajectories.
- Velocity and Range: Optimized for muzzle velocities of 1,800-3,050 fps, effective to 500+ yards with minimal wind drift.
- Reduced Fouling: Tapered jacket minimizes barrel fouling by 10-15% compared to non-bonded bullets, extending barrel life.
Reloading requires precision, using standard dies and SAAMI-compliant COAL to manage pressures. Maintain case neck tension (0.002-0.004″) for optimal accuracy, as the AccuBond’s robust design suits demanding hunts but demands careful load development.
Ballistics and Performance
With G1 BCs ranging from 0.366 to 0.720, the AccuBond offers excellent long-range stability and wind resistance, supported by high sectional density for deep penetration. Field tests show a 140-grain 6.5mm AccuBond achieving 0.5-0.8 MOA at 300 yards with ES/SD under 15 fps from a 1:8 twist barrel. The 90-grain .243 is ideal for deer and antelope, while the 180-grain .308 excels for larger game like elk or moose, retaining energy to 500 yards.

Comparison Bullets
The AccuBond competes with Barnes TTSX (monolithic copper), Hornady InterBond (bonded polymer-tipped), and Swift Scirocco II (bonded boat-tail). Its BCs (0.366-0.720) surpass TTSX (0.295-0.586) and InterBond (0.350-0.550), offering 5-10% better long-range trajectory than Scirocco II (0.400-0.600). The AccuBond’s expansion matches InterBond at 1,800 fps but retains 5% less weight than TTSX in bone. Against TTSX 180gr .308, the AccuBond 180gr drops 5% less at 400 yards; versus Scirocco II 180gr, it penetrates similarly but expands 5% slower. Advantages: high BC, cost-effective ($0.50-$0.80 per bullet). Drawbacks: contains lead, less penetration than TTSX.
| Bullet | Diameter Range (inches) | Weight Range (grains) | BC Range | Key Feature |
|---|---|---|---|---|
| Nosler AccuBond | 0.224-0.375 | 70-300 | 0.366-0.720 | Polymer tip, bonded core |
| Barnes TTSX | 0.224-0.338 | 50-225 | 0.295-0.586 | Polymer tip, grooved monolithic |
| Hornady InterBond | 0.224-0.338 | 85-220 | 0.350-0.550 | Polymer tip, bonded core |
| Swift Scirocco II | 0.243-0.338 | 90-180 | 0.400-0.600 | Polymer tip, thick jacket bonded |
Field reports show AccuBond outperforming InterBond by 0.2 MOA at 400 yards and matching Scirocco II in penetration consistency.

Reloading
- Load Data: Refer to Nosler’s reloading manual or website for AccuBond-specific data, as the bonded design handles higher pressures than non-bonded bullets.
- Starting Charges: Begin 5-10% below maximum loads for comparable bonded bullets to avoid over-pressure; increase gradually while checking for pressure signs.
- Seating Consistency: Ensure precise seating depths (0.010-0.050″ off lands) to maximize accuracy, as the AccuBond’s ogive is sensitive to inconsistencies.
- Crimp Application: Apply a light to medium crimp on the cannelure for secure bullet retention, particularly in semi-auto or high-recoil rifles, ensuring reliable feeding.
- Barrel Twist Compatibility: Match barrel twist rate to AccuBond weight (e.g., 1:12 for 70gr .224, 1:8 for 140gr 6.5mm) for proper stabilization and optimal accuracy.
- Velocity Check: Chronograph to confirm velocities above 1,800 fps for reliable expansion, targeting extreme spreads under 15 fps.
- Storage: Store in sealed containers to protect from moisture; suitable for all hunting applications per design.
Conclusion
Nosler AccuBond is a premium bonded hunting bullet, blending high ballistic coefficients with reliable penetration and expansion. Its long-range precision makes it ideal for hunters pursuing big game at distance. Visit official website.
