Understanding and maintaining your Dillon powder measure is crucial for consistent and safe reloading. This guide dives deep into the various Dillon powder measure parts, their functions, troubleshooting common issues, and sourcing replacement components. We'll cover everything from the basic components to advanced upgrades, ensuring you get the most out of your Dillon press.
Understanding the Dillon Powder Measure System
Dillon powder measures, renowned for their accuracy and reliability, are a key component of any serious reloading setup. Their robust design and modularity allow for customization and maintenance. However, to effectively troubleshoot or upgrade, you need a solid understanding of the individual parts.
Core Components of a Dillon Powder Measure
The heart of the Dillon powder measure system typically includes:
- Powder Hopper: This large container holds your powder supply. Ensure it's clean and free of any debris to prevent malfunctions. Different sized hoppers might be available depending on your model.
- Powder Drop Tube: This tube channels powder from the hopper to the metering mechanism. Its smooth interior is crucial for consistent powder flow. Blockages here are a common cause of inconsistent charges.
- Metering Mechanism (including the rotor, cam, and disc): This is the core of the measure's accuracy. The rotor, driven by the press, rotates and meters powder based on its configuration. The cam controls the rotor's speed, while the disc regulates the amount of powder dispensed. The precise tolerances of these parts are essential for accuracy.
- Powder Charge Bar: This bar collects the measured powder charge. Its design prevents powder spillage and ensures consistent transfer to the case.
- Case Activation Mechanism: This interacts with the reloading press to trigger the powder drop. This is usually a lever or similar mechanism.
- Adjusting Screws: These screws, often found on the metering mechanism, allow for precise adjustments to the powder charge weight. Small adjustments here can significantly impact accuracy.
- Body/Housing: This is the main framework that holds all the other components together. Ensure it is securely fastened and free from damage.
Common Dillon Powder Measure Issues and Troubleshooting
Many issues with Dillon powder measures stem from simple problems with these components. Here's a breakdown of common problems and solutions:
Inconsistent Powder Charges
- Problem: Powder charges vary significantly from one round to the next.
- Possible Causes: Dirty or damaged metering mechanism, worn rotor, incorrect adjustment, powder bridging in the hopper, improper powder type.
- Solution: Carefully inspect the metering mechanism for debris, damage, or wear. Clean thoroughly and ensure the rotor spins freely. Check adjustment screws and powder flow. Consider changing to a powder that flows better.
Powder Spillage
- Problem: Powder spills from the measure during operation.
- Possible Causes: Damaged powder charge bar, misaligned components, improper seating of the powder drop tube.
- Solution: Check for damage to the powder charge bar and ensure all components are properly aligned and secured. Make sure the powder drop tube is seated correctly.
Jamming or Sticking
- Problem: The metering mechanism jams or sticks during operation.
- Possible Causes: Static electricity (especially with certain powders), clogged powder tube, damaged rotor, or worn cam.
- Solution: Try using an anti-static powder funnel or applying a slight lubricant to the rotor (use a reloading-specific lubricant). Thoroughly inspect the powder tube and clear any blockages.
Sourcing Replacement Parts
Finding replacement parts for your Dillon powder measure is generally straightforward.
- Dillon Precision, Inc.: The manufacturer is the best source for genuine parts, ensuring compatibility and quality. Their website offers parts diagrams and ordering information.
- Online Retailers: Numerous online retailers specialize in reloading supplies and carry a wide selection of Dillon parts.
- Local Reloading Shops: Your local reloading shop might carry common replacement parts or can order them for you.
Upgrade and Customization Options
Beyond basic maintenance, you can upgrade your Dillon powder measure to enhance its functionality and precision. These include:
- Different Metering Discs: These allow you to adapt to different powder types and charge weights.
- Improved Hoppers: Larger capacity hoppers can reduce the frequency of refills.
- Micro-Adjusting Mechanisms: Some aftermarket adjustments allow for even finer tuning of charge weights.
Remember, always prioritize safety when working with reloading equipment. Regular cleaning and inspection of your Dillon powder measure parts are essential to ensure accurate and safe reloading practices.
Conclusion
Understanding the intricacies of your Dillon powder measure parts empowers you to maintain your equipment, troubleshoot problems effectively, and maximize its precision. By following the steps outlined above, you can ensure years of reliable and safe reloading. Don't hesitate to consult your Dillon manual and the manufacturer's website for detailed information specific to your model.
