Lee Precision is a popular choice for reloaders, especially beginners, due to its affordable equipment and comprehensive reloading manuals. This guide delves into Lee's 9mm reloading data, offering insights into safe and effective reloading practices. Understanding and correctly using Lee's data is crucial for consistent and accurate ammunition, ensuring both safety and performance. We'll cover everything from choosing the right components to understanding the data tables themselves.
Understanding Lee Reloading Manuals
Lee's reloading manuals, available both in print and online, are a valuable resource. They provide detailed information on various calibers, including 9mm, outlining specific powder charges, bullet weights, primers, and overall cartridge lengths (OAL). It's crucial to always use the most up-to-date version of the manual, as data can change based on powder manufacturer updates and component variations. Never rely on outdated information.
Key elements to understand in a Lee manual:
- Powder Type and Charge: This is the heart of the data. Lee will list specific powders (e.g., Unique, Titegroup, Power Pistol) and the corresponding recommended charge weight in grains. Variations here can lead to dangerous over-pressure or under-powered rounds.
- Bullet Weight: Bullet weight is another critical factor. Heavier bullets generally require more powder to achieve optimal velocity. The manual will specify compatible bullet weights for each powder/charge combination.
- Primer Type: The manual will recommend specific primer types (e.g., small pistol magnum, small pistol). Using the wrong primer can affect ignition reliability and pressure.
- Overall Cartridge Length (OAL): OAL is the total length of the loaded cartridge. Incorrect OAL can lead to malfunctions or dangerous pressure increases. Lee provides recommended OAL for each load.
- Case Type: Lee may specify brass case manufacturers or types for optimal results.
Lee 9mm Reloading Data: A Sample
Lee's data varies depending on the edition of their manual and the specific powders and bullets in use. The following is a sample data set and should never be used without consulting the latest Lee Precision reloading manual for your specific components. Always double-check your data.
Powder | Bullet Weight (grains) | Powder Charge (grains) | Primer | OAL (inches) |
---|---|---|---|---|
Unique | 115 | 4.0 | Small Pistol | 1.130 |
Titegroup | 124 | 4.5 | Small Pistol | 1.125 |
Power Pistol | 147 | 5.0 | Small Pistol Mag | 1.140 |

Safety First: Essential Precautions
Reloading is inherently dangerous. Failure to follow safety protocols can result in serious injury or death. Here are some key safety precautions:
- Read and understand the entire Lee reloading manual before starting. This cannot be overstated.
- Use a scale that is accurate to 0.1 grain. Improper powder charges are a leading cause of accidents.
- Always wear safety glasses and hearing protection.
- Work in a clean, well-ventilated area.
- Never mix different powder types or use outdated powder.
- Inspect each loaded round carefully before use.
- Start at the minimum charge weight listed and work up gradually, always carefully monitoring pressure signs.
- Never exceed the maximum listed charge weight.
- Properly dispose of any malfunctioning or improperly loaded ammunition.
Troubleshooting Common Issues
Even with careful attention to detail, problems can occur. Here are some common issues and potential solutions:
- Squib Loads: A squib load occurs when a round fails to fully detonate. This can damage your firearm. Always visually inspect your cases and cartridges for abnormalities before firing.
- High Pressure Signs: These include unusually hard bolt cycling, excessive case stretching, or primers flattened excessively. If observed, stop immediately, assess your process, and reconsider your reloading procedure. Consult the Lee manual for detailed guidance on pressure issues.
- Inconsistent Reloads: This often points to issues with the reloading process itself (e.g., inconsistent powder measures, bullet seating depth).
Conclusion: Responsible Reloading with Lee Data
Lee reloading data for 9mm, when used responsibly and with meticulous attention to detail, can provide accurate and economical ammunition. Remember, safety is paramount. Always consult the current Lee Precision manual, meticulously follow the instructions, and never compromise on safety. By doing so, you can confidently and safely enjoy the benefits of reloading your own 9mm ammunition.
