Lehigh Defense ammunition is known for its innovative bullet designs, focusing on maximizing terminal performance and minimizing overpenetration. For reloaders, this presents both an exciting opportunity and a challenge. While Lehigh doesn't provide load data directly, understanding their bullet characteristics is crucial for safe and effective reloading. This guide provides a comprehensive overview, emphasizing safety and responsible reloading practices.
Disclaimer: This information is for educational purposes only. Always consult your reloading manual and independently verify load data before attempting to reload any ammunition. Improper reloading techniques can lead to serious injury or death. Never exceed the maximum listed pressure for your specific firearm and powder.
Understanding Lehigh Defense Bullets
Lehigh Defense offers a range of unique bullet designs, each optimized for a specific application. Key characteristics impacting reloading include:
- Controlled Chaos™: This design features a segmented bullet that expands aggressively upon impact, creating a significant wound cavity while minimizing overpenetration. This fragmentation can affect pressure curves compared to monolithic bullets.
- Extreme Penetrator™: Designed for deep penetration, these bullets are typically heavier and have a different pressure profile than hollow-point designs.
- Subsonic/Supersonic: The bullet's velocity significantly impacts pressure. Load data for subsonic loads will differ greatly from supersonic.
Finding Reliable Lehigh Defense Load Data
Because Lehigh Defense focuses on manufacturing, not reloading data, you'll need to adopt a more hands-on approach. This involves:
1. Start with a Known Starting Load:
Begin with load data for a similar bullet weight and profile from a reputable reloading manual (e.g., Lyman, Hornady, Sierra). Choose a load near the minimum end of the range. This acts as a conservative starting point. Remember, Lehigh bullets may behave differently.
2. Use a Gradual Increase Method:
Increase the powder charge incrementally (e.g., 0.1 grains at a time) while carefully monitoring pressure signs. Observe for excessive pressure signs like flattened primers, excessive case head expansion, or unusual sounds from the firearm.
3. Chronograph Your Loads:
Use a chronograph to measure velocity at each increment. This data helps you correlate velocity with pressure. Aim for consistent velocities within a reasonable range.
4. Pressure Testing:
While not feasible for every reloader, having your loads pressure tested by a professional is the gold standard. This ensures safety and provides precise pressure data for your specific setup.
5. Record Keeping:
Maintain meticulous records of each load, including powder type, powder charge, bullet weight, primer type, case type, and observed velocity and pressure signs. This invaluable information forms the basis of your personal load data.
Crucial Considerations for Lehigh Defense Reloading:
- Bullet Seating Depth: Pay close attention to bullet seating depth. Improper seating can lead to inaccurate shots and potentially unsafe pressure levels.
- Powder Type: Experiment with different powders to find one that provides optimal accuracy and consistency with Lehigh bullets. Some powders are better suited for certain bullet weights and velocities.
- Case Preparation: Thorough case preparation, including resizing, trimming, and cleaning, is essential for consistent performance and safety.
- Safety First: Always wear appropriate safety gear (eye protection, hearing protection) when reloading. Never reload in an unsafe environment.
Conclusion: Responsible Reloading with Lehigh Defense
Reloading Lehigh Defense ammunition requires a methodical and cautious approach. There is no substitute for careful observation, meticulous record-keeping, and understanding the unique characteristics of Lehigh's bullet designs. By following these guidelines and prioritizing safety, you can safely and effectively develop your own reliable load data for this innovative ammunition. Remember, the responsibility for safe reloading rests solely with the reloader.
