The .308 Winchester remains a popular choice for long-range precision shooting, and the Hornady 175gr Sub-X bullet is a favorite among competitive shooters and hunters seeking exceptional accuracy at extended ranges. This article dives deep into load data for this exceptional combination, exploring various powder choices, optimal velocities, and safety considerations. Remember, always consult your specific reloading manual before attempting any reloading. This information is for educational purposes only.
Understanding the Hornady 175gr Sub-X Bullet
The Hornady 175gr Sub-X bullet is designed for superior accuracy and long-range performance. Its design incorporates a boat-tail base and a secant ogive, minimizing drag and promoting stability at extended distances. The Sub-X's high ballistic coefficient (BC) translates to less wind drift and a flatter trajectory, crucial for precision shooting. This makes it a top choice for target shooting, hunting larger game at longer ranges, and competitive shooting disciplines.
Powder Selection: Finding the Right Match
Finding the right powder is crucial for optimal performance and safety. Several powders are well-suited for the 175gr Sub-X in .308 Winchester. Remember that different powders react differently in different rifles, so experimentation is key to finding the best load for your specific firearm. Always start low and work your way up, meticulously observing safety protocols.
Here are a few powders frequently used, but this is not an exhaustive list:
- Varget: Known for its excellent metering characteristics and consistent performance across a wide range of temperatures, Varget is a popular choice for many .308 Winchester loads, including those featuring the 175gr Sub-X.
- RL15: Another excellent choice providing consistent accuracy and manageable recoil.
- IMR 4064: A versatile powder suitable for a broad range of bullet weights in the .308 Winchester, offering good accuracy with the 175gr Sub-X.
- IMR 4895: A time-tested powder providing reliable performance.
Note: The optimal powder charge will vary depending on the specific powder, rifle, and other components used. Never exceed the maximum recommended charge listed in your reloading manual.
Load Data Considerations and Safety
Developing a reliable and accurate load requires careful attention to detail. Consider these critical aspects:
- Case Preparation: Consistent case preparation, including resizing, trimming, and priming, is essential for consistent performance.
- Bullet Seating Depth: Proper bullet seating depth significantly impacts accuracy. Start with the recommended seating depth in your reloading manual and make small adjustments as needed to fine-tune accuracy.
- Primer Selection: Use a standard large rifle primer.
- Chronographing: Use a chronograph to measure velocity and ensure consistency between loads. This is crucial for verifying your load's performance and ensuring safety.
- Safety First: Always wear appropriate safety equipment, including safety glasses and hearing protection. Reload in a well-ventilated area, free from distractions.
Finding Your Perfect Hornady 175gr Sub-X Load
The journey to finding the perfect load for your specific rifle and preferences involves testing and experimentation. Start with the minimum recommended charge listed in your reloading manual and incrementally increase the charge while carefully observing pressure signs. Pay close attention to accuracy at various ranges. Each increment should be small (0.1-0.2 grains), and a thorough cleaning of your rifle between tests is recommended.
