Finding the perfect load data for your Hornady 165 grain SST bullets in .308 Winchester can significantly impact accuracy and performance. This guide provides comprehensive information, but always remember: This information is for guidance only. Always consult your reloading manual and Hornady's official data before loading ammunition. Improper reloading practices can lead to serious injury or death.
Understanding the Hornady 165 SST
The Hornady 165 grain SST (Subsonic Solid Tip) bullet is a popular choice for hunting and target shooting. Its design incorporates a solid polymer tip for controlled expansion and consistent performance, making it effective on various game animals. The subsonic designation signifies its suitability for suppressed firearms, although it can be used in non-suppressed rifles as well.
Factors Affecting Load Data
Several factors influence optimal load data for your specific setup. These include:
- Rifle: The twist rate of your rifle barrel significantly impacts bullet stability and accuracy. A faster twist rate might be better suited to heavier bullets, while slower twist rates work well with lighter projectiles. Check your rifle's specifications.
- Powder: Different powders burn at different rates, influencing pressure and velocity. Using the wrong powder can be dangerous. Consult your reloading manual for compatible powders.
- Primer: Primer type (small rifle, large rifle) can affect ignition consistency and pressure.
- Case Capacity: Variations in brass case capacity from different manufacturers can influence the final pressure and velocity.
Finding Reliable Load Data Sources
Beyond consulting Hornady's official loading data, reputable sources for reloading information include:
- Hornady's Website: Their website is the best starting point, offering detailed load data for their products.
- Reloading Manuals: Published manuals from reputable sources like Lyman, Sierra, and Lee provide comprehensive information and safety guidelines.
- Online Forums: Online forums focused on reloading can provide valuable insights from experienced reloaders. However, always verify information from multiple sources and prioritize safety. Never rely solely on online forums for load data.
Developing Your Loads: A Step-by-Step Approach
Once you've consulted your manual and chosen a starting load from a reputable source, the process involves gradually working up to your optimal load. Start low and work up. Never exceed maximum loads listed in your manual.
- Start with the minimum load: Begin with the lowest recommended powder charge specified in your chosen data source.
- Careful Measurement: Precise measurement of powder is crucial for safety and consistency. Use a reliable powder scale.
- Consistent Procedures: Follow consistent reloading procedures. Maintain uniformity in bullet seating depth, crimp, and overall cartridge length.
- Observe Pressure Signs: Monitor for signs of excessive pressure, including flattened primers, bulged cases, or unusually high temperatures.
- Chronographing: Using a chronograph allows you to measure the velocity of your loads. This helps you to better understand your load development.
- Accuracy Testing: Finally, test your loads for accuracy at various ranges.
Safety First: Crucial Considerations
- Never exceed maximum loads. Doing so can result in catastrophic firearm failure.
- Always wear safety glasses and hearing protection when reloading.
- Keep your workspace clean and organized.
- Properly dispose of spent primers and powder residue.
- Never mix different powders.
- Store ammunition in a cool, dry place.
Conclusion
Reloading your own .308 Winchester ammunition using Hornady 165 grain SST bullets can be a rewarding experience, providing you with precision-crafted ammunition tailored to your specific rifle. However, always prioritize safety and meticulously follow established procedures and recommended load data. Remember that the information provided here is for general guidance only and should not replace consulting reliable sources and manuals. Safe and responsible reloading practices are essential.
