The Lee Auto Disk Powder Measure is a popular choice among reloaders, prized for its simplicity, affordability, and surprisingly accurate performance. This guide delves deep 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 out, understanding the Lee Auto Disk Powder Measure will significantly enhance your reloading experience.
Understanding the Lee Auto Disk Powder Measure's Mechanism
At its core, the Lee Auto Disk Powder Measure operates on a simple but effective principle: a rotating disk with precisely sized holes meters the powder charge. The size of the hole determines the amount of powder dispensed with each throw. This system is remarkably consistent once properly calibrated, making it suitable for a wide range of cartridges and powder types.
Key Components and Features:
- Rotating Disk: The heart of the system, featuring multiple interchangeable disks for different powder charges.
- Adjustable Powder Hopper: Allows for easy filling and control of the powder supply.
- Case Activation Mechanism: Typically a simple lever or cam that activates the powder drop.
- Precise Calibration: Allows for fine-tuning to ensure consistent powder charges.
Advantages of Using the Lee Auto Disk Powder Measure
- Affordability: The Lee Auto Disk Powder Measure is significantly cheaper than many other powder measures on the market, making it an accessible entry point for new reloaders.
- Simplicity: Its straightforward design makes setup and use relatively easy, even for beginners.
- Accuracy: While not as precise as some electronic measures, the Lee Auto Disk, when properly calibrated and maintained, delivers surprisingly consistent charges.
- Versatility: The interchangeable disks offer flexibility to handle various powder types and cartridge requirements.
- Durability: Lee products are known for their robust construction, and the Auto Disk is no exception.
Potential Drawbacks and Limitations
- Manual Operation: Unlike electronic measures, the Lee Auto Disk requires manual operation, which can be slower for high-volume reloading.
- Sensitivity to Powder Type: Certain powder types might be more challenging to meter accurately compared to others. Flaky or overly fine powders can be particularly problematic.
- Calibration Requires Patience: Achieving optimal accuracy requires careful calibration and adjustment.
- Limited Charge Range with Single Disk: While interchangeable disks provide versatility, a single disk only handles a specific charge range.
Optimizing Performance: Tips and Techniques
- Proper Calibration: This is paramount. Start with a small sample of cases and weigh each charge carefully to fine-tune the disk's adjustment for consistency.
- Consistent Powder Flow: Ensure the powder hopper is adequately filled and that the powder flows freely. Avoid bridging or clumping.
- Cleanliness: Regular cleaning is crucial to prevent powder buildup and maintain accuracy.
- Disk Selection: Choose the appropriate disk for your chosen powder and cartridge.
- Environmental Factors: Temperature and humidity can affect powder flow; consider these variables during calibration and use.
Lee Auto Disk Powder Measure vs. Other Powder Measures
The Lee Auto Disk often gets compared to other powder measures, both manual and electronic. While electronic measures offer superior speed and often greater precision, the Lee Auto Disk shines in its simplicity, affordability, and surprisingly good accuracy for its price point. The choice often boils down to budget, reloading volume, and desired level of precision.
Conclusion: Is the Lee Auto Disk Right for You?
The Lee Auto Disk Powder Measure is an excellent choice for reloaders who prioritize affordability, simplicity, and adequate accuracy. While it may not be the fastest or most precise option, its ease of use and reliable performance make it a strong contender, especially for beginners or those reloading smaller quantities of ammunition. However, high-volume reloaders or those requiring extreme accuracy might find an electronic measure more suitable. Careful calibration and consistent maintenance are key to unlocking the full potential of this popular reloading tool.
