The Lyman 55 powder measure is a mainstay in many reloading benches, known for its reliability and ease of use. This guide delves into the specifics of this popular measure, exploring its features, benefits, and potential drawbacks, helping you determine if it's the right choice for your reloading needs.
Understanding the Lyman 55's Design and Functionality
The Lyman 55 is a single-stage powder measure, meaning it dispenses one charge of powder at a time. This contrasts with progressive presses which dispense multiple charges simultaneously. Its design utilizes a positive displacement system, ensuring consistent powder throws, crucial for accurate and safe reloading. The heart of the system is a rotating disc with adjustable cavities that control the amount of powder dispensed.
Key Features:
- Micrometer Adjustment: Allows for precise adjustments to powder charge weight, minimizing variations between charges. This is critical for consistent bullet velocities and accuracy.
- Large Capacity Hopper: Holds a substantial amount of powder, reducing the frequency of refills and speeding up the reloading process.
- Durable Construction: Built from robust materials, ensuring longevity and reliable performance even with frequent use.
- Versatile Compatibility: The Lyman 55 is compatible with a wide range of reloading presses and readily available accessories.
- Easy to Clean and Maintain: Its relatively simple design allows for straightforward cleaning and maintenance, ensuring optimal performance over time.
Advantages of Using the Lyman 55 Powder Measure
The Lyman 55 offers several advantages that have cemented its place as a popular choice among reloaders:
- Accuracy: The micrometer adjustment and positive displacement system contribute to exceptionally accurate powder dispensing, a critical factor in safe and reliable reloading.
- Ease of Use: The straightforward design and intuitive operation make it ideal for both beginners and experienced reloaders.
- Affordability: Compared to some higher-end powder measures, the Lyman 55 offers excellent value for its price, making it an accessible option for many reloaders.
- Reliability: Its robust construction ensures dependable performance over extended periods, minimizing downtime and maximizing productivity.
- Widely Available: The Lyman 55 is readily available from most reloading supply vendors, making it easy to purchase and obtain replacement parts if needed.
Potential Drawbacks and Considerations
While the Lyman 55 is generally well-regarded, it's important to be aware of some potential drawbacks:
- Speed: As a single-stage measure, it's slower than progressive powder measures. This isn't a major issue for those reloading smaller batches, but it can become a time constraint for high-volume reloading.
- Powder Type Sensitivity: While generally versatile, some particularly fine or coarse powders might require more careful adjustment and attention to ensure consistent throws. Always consult your powder manufacturer's recommendations.
- Learning Curve (Minor): While relatively easy to use, a slight learning curve exists to master the precise adjustments and ensure optimal performance.
Optimizing Your Lyman 55 for Best Results
To maximize the accuracy and efficiency of your Lyman 55, consider the following tips:
- Properly Level Your Press: An unlevel press can affect the accuracy of your powder throws.
- Consistent Powder Flow: Ensure your powder is free-flowing and not clumped.
- Regular Cleaning: Clean your powder measure regularly to prevent build-up and ensure consistent powder throws.
- Start Low and Gradually Increase: When setting a new charge weight, begin with a conservative setting and gradually increase until you reach your desired weight. Always double-check your powder charges before loading your cartridges.
- Calibrate Frequently: Periodic calibration ensures accuracy and compensates for any wear and tear.
Conclusion: Is the Lyman 55 Right for You?
The Lyman 55 powder measure is a reliable and accurate tool, well-suited for many reloaders. Its affordability, ease of use, and robust construction make it an excellent choice for beginners and experienced reloaders alike who value accuracy and dependability. While it's not the fastest option, its advantages in accuracy and ease of use significantly outweigh this limitation for many. However, those seeking high-volume reloading capabilities might benefit from exploring progressive powder measures. Ultimately, the decision depends on your individual reloading needs and preferences.
