Introduction
Discover the Hornady InterBond, a bonded bullet designed for hunters who demand deep penetration and controlled expansion. Introduced by Hornady Manufacturing in 2003, based in Grand Island, Nebraska, the InterBond features a proprietary bonding process that fuses the core and jacket for superior performance.
Renowned for its 90%+ weight retention and reliable expansion, the InterBond delivers exceptional terminal performance, making it a top choice for ethical hunters targeting big game. Its versatile design ensures consistent results across varied hunting scenarios, from dense brush to long-range plains.
- Caliber Range: Available from .243 to .338 inches, supporting cartridges like .243 Winchester, .270 Winchester, 6.5 Creedmoor, .308 Winchester, and .300 Winchester Magnum.
- Weight Options: Spans 90 to 200 grains, with popular variants like 100-grain .243, 130-grain .270, and 165-grain .308.
- Hunting Focus: Optimized for deep penetration and consistent expansion, ideal for medium to large game in varied environments.
Technical Characteristics
The Hornady InterBond is crafted for hunters seeking durability and precision in the field. Its advanced bonded design ensures top-tier performance.
- Bonded Lead Core: Features a lead core bonded to a copper jacket, ensuring 90%+ weight retention with no core-jacket separation, even through heavy bone.
- Polymer-Tipped Design: Includes a red polymer tip and hollow-point cavity for controlled expansion at velocities as low as 1,700 fps, achieving 1.5-2x diameter expansion.
- Boat-Tail Profile: Streamlined boat-tail design enhances ballistic efficiency and reduces drag for flat trajectories.
- Velocity and Range: Optimized for muzzle velocities of 2,000-3,500 fps, effective to 500+ yards with excellent stability.
- Reliable Feeding: Streamlined profile with a cannelure ensures smooth cycling in bolt-action and semi-auto rifles.
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 InterBond’s rugged design excels in tough hunts but demands careful load development.
Ballistics and Performance
With G1 BCs ranging from 0.365 to 0.547, the InterBond offers strong long-range stability and wind resistance, supported by high sectional density for deep penetration. Field tests show a 130-grain .270 InterBond achieving 0.5-0.8 MOA at 300 yards with ES/SD under 15 fps from a 1:10 twist barrel. The 100-grain .243 is ideal for deer and antelope, while the 165-grain .308 excels for larger game like elk or moose, retaining energy to 400 yards.

| 0.308 | 150 | 0.415 | 0.226 |
| 0.308 | 165 | 0.475 | 0.248 |
| 0.308 | 180 | 0.480 | 0.271 |
| 0.338 | 200 | 0.547 | 0.250 |
Groups of 0.5-0.8 MOA achievable; excels to 500 yards with proper shot placement.
Comparison Bullets
The InterBond competes with Federal Trophy Bonded (premium bonded), Nosler Partition (dual-core bonded), and Swift Scirocco II (bonded polymer-tipped). Its BCs (0.365-0.547) surpass Partition (0.300-0.500) and match Trophy Bonded (0.430-0.520), offering better long-range performance than Scirocco II (0.400-0.550) in some calibers. The InterBond’s expansion is 5-10% more consistent than Partition at low velocities (1,700 fps) but similar to Trophy Bonded in penetration. Against Trophy Bonded 165gr .308, the InterBond 165gr .308 drops 5% less at 400 yards; versus Partition 180gr .308, it penetrates 5% deeper with less fragmentation. Advantages: high BC, reliable expansion. Drawbacks: slightly higher cost ($0.40-$0.70 per bullet), not lead-free.
| Bullet | Diameter Range (inches) | Weight Range (grains) | BC Range | Key Feature |
|---|---|---|---|---|
| Hornady InterBond | 0.243-0.338 | 90-200 | 0.365-0.547 | Polymer tip, bonded core |
| Federal Trophy Bonded | 0.277-0.338 | 130-200 | 0.430-0.520 | Polymer tip, bonded core |
| Nosler Partition | 0.224-0.375 | 60-300 | 0.300-0.500 | Dual-core bonded |
| Swift Scirocco II | 0.224-0.338 | 90-180 | 0.400-0.550 | Polymer tip, bonded core |
Field reports show InterBond leading Partition by 0.2 MOA at 400 yards and outperforming Scirocco II in penetration consistency.

Reloading
- Load Data: Refer to Hornady’s reloading manual or website for InterBond-specific data, as the bonded design generates standard pressures similar to other jacketed bullets.
- Starting Charges: Begin 5-10% below maximum loads for comparable lead 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 InterBond’s bearing surface 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 InterBond weight (e.g., 1:10 for 100gr .243, 1:8 for 129gr 6.5mm) for proper stabilization and optimal accuracy.
- Velocity Check: Chronograph to confirm velocities above 1,700-2,000 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
Hornady InterBond is a premier bonded hunting bullet, blending high ballistic efficiency with reliable penetration and expansion. Its long-range precision and robust design make it a top choice for hunters pursuing big game. Visit official website.
