The Lee Auto Drum powder measure is a popular choice among reloaders, prized for its affordability and accuracy. This comprehensive guide will delve into its features, benefits, drawbacks, and how to get the most out of this versatile tool. Whether you're a seasoned reloader or just starting, understanding the nuances of the Lee Auto Drum will significantly improve your reloading process.
Understanding the Lee Auto Drum Powder Measure
The Lee Auto Drum is a progressive powder measure, meaning it dispenses a set amount of powder with each throw of the handle. Unlike volume-based measures, it relies on a rotating drum with calibrated cavities to deliver consistent powder charges. This mechanism ensures greater accuracy and repeatability compared to less precise methods. Its simple design and robust construction make it a reliable workhorse in many reloading benches.
Key Features and Benefits:
- Affordability: The Lee Auto Drum is significantly cheaper than many competing progressive powder measures, making it an excellent entry-level option or a valuable addition to a budget-conscious reloading setup.
- Ease of Use: Its straightforward design makes it relatively easy to learn and use, even for beginners. The calibration process is simple and intuitive.
- Consistent Powder Charges: The rotating drum system minimizes variations in powder drops, resulting in consistent and accurate charges. This is crucial for maintaining optimal pressure and ballistic performance in your ammunition.
- Durability: Built from sturdy materials, the Lee Auto Drum is designed to withstand the rigors of frequent use. With proper care and maintenance, it can provide years of reliable service.
- Versatility: While optimized for pistol and certain rifle calibers, with careful adjustment, the Lee Auto Drum can handle a wide range of powder types and charges.
Potential Drawbacks:
- Capacity Limitations: The drum's capacity limits the number of charges you can dispense before refilling, which can slow down high-volume reloading sessions.
- Calibration Sensitivity: While generally accurate, the calibration process requires attention to detail. Inaccurate calibration can lead to inconsistent charges and potentially dangerous overloads or underloads.
- Powder Flow Sensitivity: The performance of the Lee Auto Drum can be affected by the type and condition of the powder. Some powders may flow better than others, potentially influencing accuracy.
Optimizing Your Lee Auto Drum Powder Measure
To get the best results from your Lee Auto Drum, follow these crucial steps:
1. Proper Calibration:
Accurate calibration is paramount. Lee provides detailed instructions, but taking your time and using a scale to verify each setting is essential for safety and consistency. Remember to always double-check your powder charges with a scale.
2. Maintaining Cleanliness:
Keep the drum and associated components clean and free of debris. Regular cleaning helps prevent powder bridging and ensures consistent powder flow.
3. Using the Correct Powder:
Certain powders flow better than others in the Lee Auto Drum. Experiment to find which powders work best with your specific setup. Avoid using powders that are prone to clumping or bridging.
4. Consistent Technique:
Develop a consistent throwing technique to minimize variations in powder drops. Avoid jerky movements and maintain a steady rhythm.
Conclusion:
The Lee Auto Drum powder measure offers a compelling balance of affordability, accuracy, and ease of use. While it may have some limitations compared to more expensive models, its reliability and performance make it a strong contender for reloaders of all levels. By understanding its capabilities and limitations, and by following proper calibration and maintenance procedures, you can significantly enhance your reloading process and achieve consistent, accurate powder charges. Remember, safe reloading practices are paramount. Always double-check your work and consult your reloading manuals for specific instructions on your chosen cartridges.
