The Belding & Mull powder measure is a classic piece of reloading equipment known for its precision and reliability. For decades, reloaders have relied on its consistent powder drops, contributing to safer and more accurate ammunition. This guide delves into the intricacies of using a Belding & Mull powder measure, covering setup, operation, and troubleshooting, to help you get the most out of this time-tested tool.
Understanding the Belding & Mull Design
The Belding & Mull powder measure's design is ingenious in its simplicity. Unlike some more modern measures, it relies on a simple, gravity-fed system. This system, while seemingly basic, allows for impressive accuracy when properly calibrated and used. The core components include:
- The Hopper: A large capacity hopper holds your powder. Ensure it's clean and free from debris before each use.
- The Powder Measure Body: This houses the mechanism that dispenses the powder. Regular cleaning is vital for consistent performance.
- The Adjustment Mechanism: Allows precise calibration of the powder charge weight. This is the key to accurate reloading.
- The Drop Tube: This directs the powder into your case. Ensure it's properly aligned and free from obstructions.
Key Advantages of the Belding & Mull System
- Accuracy: With proper calibration, the Belding & Mull delivers remarkably consistent powder charges.
- Simplicity: The design is straightforward, making it easy to learn and maintain.
- Durability: These measures are built to last, often withstanding years of use.
- Versatility: While primarily designed for rifle cartridges, with the right adjustments it can often be used for pistol calibers.
Setting Up Your Belding & Mull Powder Measure
Proper setup is crucial for accurate and safe reloading. Follow these steps meticulously:
- Cleanliness is Paramount: Thoroughly clean your measure before beginning. Powder residue can impact accuracy. Use a dedicated reloading brush and compressed air to ensure no powder remains.
- Choosing the Right Powder: The type of powder can affect your measure's performance. Some powders flow better than others. Experiment to find the optimal settings for your specific powder.
- Calibrating the Measure: This is the most critical step. Use a scale to carefully measure the powder dispensed by your measure. Adjust the mechanism until you achieve the desired charge weight consistently. Start with small adjustments. Remember to always double-check weights for safety.
Dealing with Difficult Powders
Some powders are notoriously fickle, clumping or sticking. Here are some tips:
- Powder Temperature: Warm powders flow more readily. Work in a heated space, or allow your powder to sit in the hopper for a while to adjust to room temperature.
- Powder Conditioners: In some instances, a powder conditioner might improve flow. Use a reputable conditioner specifically designed for this purpose.
- Hopper Size: A larger hopper can mitigate issues with powder flow in some cases, as larger batches are less likely to create flow problems.
Operating Your Belding & Mull Powder Measure Safely
- Always check the weight on a scale: Never assume your powder measure is delivering the correct charge. Double-checking is non-negotiable for safety and precision.
- Regular maintenance: Inspect the measure for wear and tear. Lubricate moving parts as needed.
- Keep it clean: Clean your measure after each reloading session. Even a small amount of powder residue can impact accuracy over time.
Troubleshooting Common Belding & Mull Issues
- Inconsistent powder charges: Check for powder flow issues, re-calibrate your measure, ensure the measure itself is clean and free from obstructions.
- Powder bridging: Adjust the hopper to ensure smooth powder flow and possibly use a powder conditioner.
- Measure malfunctions: If the measure becomes damaged or malfunctions beyond simple cleaning or adjustment, refer to a professional gunsmith or the manufacturer's instructions for repairs or replacement parts.
Conclusion: Precision and Safety with the Belding & Mull
The Belding & Mull powder measure is a testament to simple, effective design. With proper care and calibration, it can deliver highly consistent powder charges. Remember that safe reloading practices are paramount, and always double-check your powder charges before loading ammunition. By adhering to these guidelines, you can ensure many years of accurate and safe reloading with your Belding & Mull powder measure.
