Importance of the Lee Auto Disc
The Lee Auto Disc Powder Measure is a favorite among reloaders of all experience levels. Its straightforward design and user-friendly operation make it an excellent choice for beginners, while its speed and precision are appreciated by seasoned reloaders. The measure’s primary function is to accurately and consistently dispense a measured amount of smokeless powder into a cartridge case.
Understanding the Lee Auto Disc Powder Measure
Interchangeable Discs
At the heart of this powder measure’s operation is the system of interchangeable discs. Instead of a manually adjustable drum or piston, the Lee Auto Disc Powder Measure utilizes a series of precisely sized, pre-drilled discs. These discs come in various sizes, each capable of dispensing a specific volume of powder. By selecting the appropriate disc for your chosen powder and desired charge weight, you can quickly and easily meter the correct amount of powder for your reloading project. This disc system is a significant advantage of the Lee Auto Disc, setting it apart from some other powder measures.
Cost-Effectiveness and Design
The Lee Auto Disc Powder Measure is also praised for its cost-effectiveness. Compared to more elaborate powder measures, it is relatively inexpensive, making it an accessible option for reloaders on a budget. However, its affordability doesn’t compromise its performance. This powder measure is constructed from durable materials and, with proper care, can provide years of reliable service. It also boasts a compact design, making it suitable for reloading benches with limited space. Its ease of use is a major plus. The measure is simple to set up, operate, and maintain, allowing reloaders to spend more time reloading and less time wrestling with complicated equipment.
What is the Lee Auto Disc Powder Measure Chart?
Definition and Purpose
So, what is the *Lee Auto Disc Powder Measure Chart*? Essentially, it’s a handy reference guide that serves as a starting point for determining which disc to use with various powders and desired charge weights. The chart is provided by Lee Precision, the manufacturer of the powder measure, and it’s designed to simplify the reloading process. It’s a crucial tool for the reloader, especially those new to the hobby.
Function and Benefits
The primary function of the chart is to provide approximate powder charge recommendations. This helps reloaders quickly find a starting point for their loads. The chart takes the guesswork out of determining which disc will dispense the desired powder volume. This reduces the amount of time spent experimenting and reduces the potential for errors.
Locating the Chart
Where exactly does one find this invaluable resource? Typically, the *Lee Auto Disc Powder Measure Chart* is included with the purchase of a new Lee Auto Disc Powder Measure. You will find it inside the packaging or within the instruction manual. Additionally, the chart is often available for download on the Lee Precision website, or you may find it readily available on popular reloading forums and websites. Having multiple copies, both physical and digital, is a good practice.
Format and Access
The format of the *Lee Auto Disc Powder Measure Chart* is designed for clarity and ease of use. It’s typically presented as a table with columns that indicate key information. The first column lists different types of smokeless powders. Adjacent columns then show the corresponding disc number to use for a particular powder and the approximate charge weight that disc will dispense. Because powder density varies significantly, the charge weights are estimates, and it is essential to always verify the charge with a calibrated scale.
The chart provides a structured, accessible way to access the information needed for reloading. Reloading manuals often contain very detailed information, and while these manuals are essential, the *Lee Auto Disc Powder Measure Chart* distills the key information needed to start reloading with the Lee Auto Disc Powder Measure into an easily understandable format.
Using the Lee Auto Disc Powder Measure Chart
Powder and Disc Selection
Using the chart is easy. It starts with the selection of your powder of choice. Next, find the appropriate disc number for that powder and the desired charge weight from the chart. The disc number corresponds to one of the interchangeable discs that come with the measure.
Installation and Dispensing
After selecting the appropriate disc, the next step is to install it into the Lee Auto Disc Powder Measure. The measure usually comes with clear instructions on how to install and secure the disc. Ensure the disc is properly seated and the rotor mechanism is functioning correctly. Once the disc is installed, you can begin dispensing powder. Be sure to test your powder charge using a calibrated scale, verifying that the measured weight is within the recommended range.
Safety First
When working with firearms and ammunition, it is always necessary to prioritize safety. Never handle firearms or reloading components without proper training. Wear appropriate safety glasses to protect your eyes from potential hazards such as powder spills or projectiles. Additionally, reload in a well-ventilated area to minimize exposure to any fumes or dust.
Limitations and Considerations
Accuracy and Variations
The Lee Auto Disc Powder Measure Chart, while extremely helpful, is not a guarantee of perfect accuracy. The chart provides a valuable starting point, but factors such as powder density, lot variations, and the specific components used in your reloading process can affect the charge weight.
Powder Density and Scale Importance
Powder density, the amount of powder that occupies a given volume, is a crucial factor in reloading. Different powders have varying densities. Furthermore, variations can also occur between different lots of the same powder. This is why weighing each charge is so important.
Reloading Scale
A digital reloading scale is an indispensable tool for reloaders. It allows for the precise measurement of each powder charge. By weighing the powder charge dispensed by the Lee Auto Disc Powder Measure, you can verify the accuracy of the chart and make necessary adjustments to achieve the desired results.
Calibrating and Adjusting the Powder Measure
Initial Setup and Testing
The best practice is to start with a charge that is slightly below the minimum recommended load in your reloading manual. Then, carefully weigh each powder charge dispensed by your Lee Auto Disc Powder Measure, comparing it to the target weight. If the measured weight is consistently off, adjust the measure or try another disc.
Adjustments and Fine Tuning
The Lee Auto Disc Powder Measure can be calibrated to ensure that it dispenses the correct amount of powder. You can adjust the measure by slightly modifying the position of the disc or rotor. Most reloaders use a digital scale and carefully measure the powder dispensed from the measure, using it as a guide to make small adjustments to the disc position.
Tips for Reloading Success
Common Issues
When using any powder measure, it’s possible to encounter various issues. One common problem is powder bridging, where powder granules become lodged within the measure, preventing consistent dispensing. Another is inconsistent charges, which can be caused by variations in powder density or the improper operation of the measure.
Troubleshooting
If powder bridging occurs, try tapping the measure gently to dislodge any granules. Ensure the measure is clean and free of any obstructions. If you notice inconsistent charges, double-check the setting of the measure. Experiment with slightly varying disc sizes and also ensure that the powder is flowing freely through the measure.
Reloading Techniques
For the best results with the Lee Auto Disc Powder Measure, experiment with different loads. Reloading manuals provide a range of loads for any given cartridge. Reloading can be an iterative process. Do some research and experiment to find the most accurate load for your firearm.
Powder Selection and Records
Different smokeless powders are formulated for different types of cartridges and bullet weights. Some are better suited for pistols, while others are optimized for rifles. Reloading manuals provide detailed information about the powders appropriate for specific cartridges. Selecting the right powder is essential for achieving optimal performance and safety.
Keeping detailed records of your reloading efforts is also important. Record each load you develop, including the powder type, the disc number used, the charge weight, and the resulting performance. This allows you to track your progress, identify any problems, and refine your loads.
Conclusion
