The Lee Pro Auto Disk Powder Measure is a popular choice among reloaders, known for its affordability and surprisingly accurate performance. This detailed guide will explore its features, benefits, drawbacks, and help you decide if it's the right powder measure for your reloading needs.
Understanding the Lee Pro Auto Disk Powder Measure
The Lee Pro Auto Disk Powder Measure is a progressive powder measure, meaning it dispenses powder with each press of the handle. Unlike volumetric measures, which dispense powder based on volume, the Lee Pro Auto Disk uses a precisely sized disk to meter out a consistent weight of powder. This makes it significantly more accurate than volumetric measures, especially crucial for precise cartridge loading.
Key Features & Benefits:
- Affordability: This is arguably its biggest selling point. The Lee Pro Auto Disk is significantly cheaper than many of its competitors, making it accessible to reloaders on a budget.
- Accuracy: While not as precise as some high-end electronic powder measures, the Lee Pro Auto Disk provides surprisingly consistent powder charges, especially when properly adjusted and maintained.
- Simplicity: It's relatively easy to set up and use, making it ideal for both beginners and experienced reloaders.
- Versatility: It can handle a wide range of powder types and charges, making it suitable for various calibers and cartridge types. The system of interchangeable disks allows for adjustments to accommodate different powder weights.
- Durability: Lee Precision products are generally known for their rugged construction, and the Auto Disk is no exception. It's built to withstand the rigors of consistent use.
Potential Drawbacks:
- Manual Operation: Unlike electronic powder measures, the Lee Pro Auto Disk requires manual operation, which can be slower, especially for high-volume reloading.
- Sensitivity to Powder Flow: The accuracy of the measure can be affected by factors like powder condition (humidity) and flow characteristics. Different powders might require more careful adjustment and troubleshooting.
- Limited Adjustability: While the interchangeable disks offer some adjustability, fine-tuning might require more effort compared to some electronic models.
- Potential for Inconsistency: While generally accurate, inconsistencies can arise if not properly maintained and calibrated. Regular cleaning and careful attention to detail are essential.
Setting Up and Using the Lee Pro Auto Disk
Proper setup is crucial for achieving accurate powder charges. The manual provides detailed instructions, but here are some key points:
- Choosing the Correct Disk: Select the disk appropriate for your desired powder charge.
- Calibration: Always calibrate your powder measure using a scale to ensure accuracy. This involves making small adjustments to achieve the desired weight consistently.
- Powder Flow: Ensure consistent powder flow by using a funnel and avoiding overly fine or damp powder.
- Maintenance: Regularly clean the measure to prevent powder buildup and maintain accuracy.
Lee Pro Auto Disk vs. Other Powder Measures
The Lee Pro Auto Disk occupies a specific niche in the market. It's a great entry-level option or for those on a budget who require decent accuracy. However, high-volume reloaders or those seeking ultimate precision might prefer more expensive electronic powder measures offering greater speed and accuracy.
Conclusion: Is the Lee Pro Auto Disk Right for You?
The Lee Pro Auto Disk Powder Measure offers a compelling balance of affordability, accuracy, and simplicity. While it might not possess the advanced features of higher-end models, it's a reliable and capable tool for many reloaders. If you're starting out or need a cost-effective way to achieve accurate powder charges, the Lee Pro Auto Disk deserves serious consideration. However, consider your reloading volume and precision needs before making a purchase. Thorough research and understanding of your specific requirements will guide you towards the perfect powder measure for your reloading journey.
