The Hornady 175gr Sub-X bullet is a popular choice among precision rifle shooters, renowned for its exceptional accuracy and consistent performance at longer ranges. However, achieving optimal results with this bullet requires careful consideration of load data and meticulous reloading practices. This guide delves into the specifics of Hornady 175gr Sub-X load data, offering insights for both experienced reloaders and those new to the craft. Remember: Always consult your firearm's owner's manual and Hornady's official reloading manual before attempting any reloading. This information is for educational purposes only and should not be considered a substitute for professional guidance.
Understanding the 175gr Sub-X Bullet
The Hornady 175gr Sub-X is a match-grade, boat-tail bullet designed for exceptional accuracy. Its heavier weight contributes to superior ballistic coefficient, reducing wind drift and maintaining velocity at extended ranges. The boat-tail design further enhances stability and accuracy. These characteristics make it a favorite for long-range precision shooting competitions and hunting applications requiring pinpoint accuracy.
Key Factors Affecting Load Data
Several factors influence the optimal load data for the 175gr Sub-X bullet. These include:
1. Caliber:
The most crucial factor is the caliber of your rifle. Load data is always caliber-specific. The 175gr Sub-X is available in various calibers, each requiring its own unique powder charge and other load parameters.
2. Rifle Twist Rate:
The twist rate of your rifle barrel significantly impacts bullet stability. An inappropriate twist rate can lead to inaccurate shot groups and potentially dangerous situations. Ensure your barrel's twist rate is compatible with the 175gr Sub-X bullet. Consult your firearm's manual or a ballistic calculator to confirm compatibility.
3. Powder Type and Quantity:
The type and amount of powder used directly affect the bullet's velocity and pressure. Using the incorrect powder or charge can result in unsafe pressures, damaging your firearm or causing injury. Never deviate from published load data without expert guidance. Experimentation should be conducted gradually and with extreme caution.
4. Primer Type:
The type of primer used can also affect ignition consistency and overall performance. Stick to the recommended primer type in your chosen load data.
5. Case Capacity:
The capacity of your brass cases impacts the amount of powder that can be safely accommodated. Using oversized or undersized cases can lead to inconsistent results or dangerous pressures.
6. Environmental Conditions:
Temperature and altitude can influence powder burn rates, impacting velocity and accuracy. Consider these factors when developing your load data, especially for long-range shooting.
Finding Reliable Load Data
The most reliable source of load data is Hornady's official reloading manual. This manual provides comprehensive data developed through rigorous testing and ensures safe reloading practices. Many online forums and websites discuss reloading, but it's crucial to prioritize information from reputable sources like the manufacturer.

Reloading ammunition is inherently dangerous. Always prioritize safety by adhering to these guidelines:
- Wear safety glasses and hearing protection.
- Work in a well-ventilated area.
- Never exceed the maximum pressure listed in the load data.
- Inspect each round carefully before firing.
- Use a reloading scale to ensure accurate powder charges.
- Clean your equipment regularly.
- If you are unsure about any aspect of reloading, seek guidance from an experienced reloader or professional.
Conclusion
Developing optimal load data for the Hornady 175gr Sub-X bullet requires careful consideration of various factors and meticulous attention to detail.
