Introduced by Hornady Manufacturing in Grand Island, Nebraska, the NTX features a copper alloy core and polymer tip for rapid expansion on small game and predators.
Known for its rapid fragmentation and high precision, the NTX ensures quick, ethical kills while meeting lead-free regulations in areas like California. Its lightweight, high-velocity design delivers flat trajectories, ideal for open-field varmint hunting.
- Caliber Range: Available from .172 to .308 inches, supporting cartridges like .17 HMR, .223 Remington, .22-250 Remington, and .243 Winchester.
- Weight Options: Spans 15.5 to 50 grains, with popular variants like 15.5-grain .172, 30-grain .223, and 50-grain .243.
- Hunting Focus: Optimized for explosive expansion on varmints and small predators, ideal for short to mid-range hunting scenarios.
Technical Characteristics
The Hornady NTX is crafted for varmint hunters who prioritize precision and eco-conscious design. Its lead-free construction ensures top-tier performance in the field.
- Copper Alloy Core: Features a copper alloy core with a thin jacket for rapid fragmentation, maximizing energy transfer on small targets.
- Polymer-Tipped Design: Equipped with a polymer tip and hollow-point cavity for explosive expansion at velocities as low as 1,600 fps.
- High Velocity Profile: Optimized for muzzle velocities of 3,000-4,200 fps, effective to 300+ yards with minimal drop.
- Reduced Fouling: Lead-free design reduces barrel fouling by 15-20% compared to lead-core bullets, supporting extended shooting sessions.
- Reliable Feeding: Streamlined profile ensures smooth cycling in bolt-action and semi-auto rifles, including AR platforms.
Reloading requires careful attention, using standard dies and SAAMI-compliant COAL to manage pressures. Maintain case neck tension (0.002-0.003″) for optimal accuracy, as the NTX’s lightweight, lead-free design demands precise load development for varmint hunting.
Ballistics and Performance
With G1 BCs ranging from 0.090 to 0.257, the Hornady NTX prioritizes high velocity and flat trajectories, ideal for varmint hunting. Field tests show a 30-grain .223 NTX achieving 0.3-0.6 MOA at 200 yards with ES/SD under 10 fps from a 1:9 twist barrel. The 15.5-grain .172 is perfect for prairie dogs and ground squirrels, while the 50-grain .243 excels for coyotes, delivering rapid energy transfer to 250 yards.
The Expert Ballistics Table below lists key NTX variants from Hornady specifications, sorted by diameter then weight. BCs are G1; verify on Hornady’s site for updates.
| Diameter (inches) | Weight (grains) | Ballistic Coefficient (BC) | Sectional Density |
|---|---|---|---|
| 0.172 | 15.5 | 0.115 | 0.075 |
| 0.204 | 24 | 0.170 | 0.082 |
| 0.224 | 30 | 0.137 | 0.085 |
| 0.224 | 35 | 0.177 | 0.100 |
| 0.243 | 50 | 0.232 | 0.121 |
| 0.308 | 50 | 0.257 | 0.075 |
Groups of 0.3-0.6 MOA achievable; excels to 300 yards with proper shot placement.
Comparison Bullets
The Hornady NTX competes with top varmint bullets like Nosler Varmageddon, Sierra BlitzKing, and Speer TNT, offering lead-free performance for small game hunting. Key strengths and limitations include:
- Strengths: High accuracy (0.3-0.6 MOA), rapid fragmentation for quick kills, and eco-friendly lead-free design ($0.35-$0.50 per bullet).
- Limitations: Lower ballistic coefficients limit performance beyond 300 yards, not suitable for big game due to fragmentation.
Compared to Nosler Varmageddon (BCs 0.110-0.365), Sierra BlitzKing (BCs 0.170-0.381), and Speer TNT (BCs 0.165-0.353), the NTX’s BCs (0.090-0.257) are lower, trailing by 10-15% in long-range stability due to its lightweight design. The NTX matches BlitzKing in fragmentation speed at 3,000 fps and outperforms Varmageddon by 5% in accuracy consistency. For example, a 30-grain .223 NTX retains ~550 ft-lbs at 200 yards, compared to ~600 ft-lbs for Varmageddon 55gr, ~620 ft-lbs for BlitzKing 55gr, and ~610 ft-lbs for TNT 50gr. It excels in eco-friendly performance but lacks the penetration of big-game bullets like Hornady GMX.
| Bullet | Diameter Range (inches) | Weight Range (grains) | BC Range | Key Feature |
|---|---|---|---|---|
| Hornady NTX | 0.172-0.308 | 15.5-50 | 0.090-0.257 | Polymer tip, lead-free fragmentation |
| Nosler Varmageddon | 0.172-0.308 | 20-110 | 0.110-0.365 | Polymer tip, rapid fragmentation |
| Sierra BlitzKing | 0.204-0.308 | 32-90 | 0.170-0.381 | Polymer tip, high accuracy |
| Speer TNT | 0.204-0.308 | 30-87 | 0.165-0.353 | Polymer tip, rapid fragmentation |
Field reports praise the NTX’s eco-friendly design and accuracy, matching BlitzKing within 0.1 MOA at 200 yards and surpassing Varmageddon in lead-free performance, making it ideal for varmint hunters in restricted areas.
Applications and Practical Aspects
Ideal for hunting:
- 15.5-24gr .172-.204 for prairie dogs and ground squirrels;
- 30-35gr .223 for varmints like groundhogs;
- 50gr .243 for coyotes and small predators;

Delivers 0.3-0.6 MOA in tuned rifles, ideal for ethical varmint kills.
Reloading
- Load Data: Refer to Hornady’s reloading manual or website for NTX-specific data, as the lightweight, lead-free design requires precise load development for high velocities.
- 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 (0.005-0.020″ off lands) to maximize accuracy, as the NTX’s lightweight design is sensitive to inconsistencies.
- Crimp Application: Apply a light crimp on the cannelure for secure bullet retention, particularly in semi-auto rifles like ARs, ensuring reliable feeding.
- Barrel Twist Compatibility: Match barrel twist rate to NTX weight (e.g., 1:12 for 15.5gr .172, 1:9 for 30gr .223) for proper stabilization and optimal accuracy.
- Velocity Check: Chronograph to confirm velocities above 3,000 fps for optimal fragmentation, targeting extreme spreads under 10 fps.
- Storage: Store in sealed containers to protect from moisture; suitable for all varmint hunting applications per design.
Conclusion
Hornady NTX is a premier lead-free varmint bullet, offering high accuracy and rapid fragmentation for quick, ethical kills. Its eco-friendly design and performance make it a top choice for varmint hunters in lead-restricted areas. Visit official website.
