Dillon powder measures are renowned for their precision and reliability in reloading, but like any mechanical device, they require proper maintenance and occasional part replacement. Understanding the various components and their functions is crucial for ensuring accurate powder charges and maintaining the longevity of your equipment. This guide provides a detailed breakdown of Dillon powder measure parts, common issues, and troubleshooting tips.
Key Components of a Dillon Powder Measure
Dillon powder measures, particularly the popular models like the 550, 650, and 750, share many common parts. While specific models might have slight variations, the core components remain consistent:
1. Powder Hopper:
- Function: Holds the powder supply. Ensures a consistent flow of powder to the metering mechanism.
- Troubleshooting: Check for obstructions, clean regularly to prevent clumping and ensure smooth powder flow.
2. Powder Measure Body:
- Function: The main housing of the powder measure, containing the metering mechanism.
- Troubleshooting: Inspect for cracks or damage. Ensure all screws and fasteners are tight.
3. Metering Mechanism (Typically a Micrometer Adjustment):
- Function: The heart of the system, precisely controlling the amount of powder dispensed per charge. This usually involves a calibrated screw for precise adjustments.
- Troubleshooting: Calibration is key. Regularly check and adjust the micrometer to ensure accuracy. Listen for any unusual sounds during operation—grinding or binding could indicate a problem.
4. Powder Drop Tube:
- Function: Guides the metered powder into the case.
- Troubleshooting: Ensure it's properly seated and free of obstructions. Replace if damaged or worn.
5. Case Activation Mechanism (Specific to press type):
- Function: This mechanism triggers the powder drop. The exact design varies depending on the Dillon press model (e.g., the primer feed system plays a role in the timing).
- Troubleshooting: Proper timing is crucial. Consult your Dillon manual for detailed troubleshooting and adjustment procedures specific to your press.
6. Calibration Tool (Often included):
- Function: Used to verify and adjust the powder measure's accuracy.
- Troubleshooting: Familiarize yourself with its use. Consistent calibration is paramount for safe and reliable reloading.
Common Problems and Solutions
Many issues with Dillon powder measures stem from simple problems:
- Inconsistent Powder Charges: This is often caused by improper calibration, dirty powder, or a faulty metering mechanism. Clean the entire system thoroughly, recalibrate, and inspect the metering mechanism for any damage.
- Powder Bridge Formation: This can occur if the powder is not flowing freely from the hopper. Use a suitable powder funnel to minimize bridging.
- Powder Sticking: Some powders are more prone to sticking than others. Use a powder specifically designed for reloading and ensure the entire system is clean and dry.
- Damage to Parts: Inspect all parts for wear and tear, particularly the drop tube and the metering mechanism. Replace worn or damaged parts promptly.
Sourcing Replacement Parts
While Dillon offers excellent customer service and readily available parts, it's crucial to only use genuine Dillon components. Using counterfeit or inferior parts can compromise the accuracy and safety of your reloading process. Contact Dillon directly or visit an authorized Dillon dealer to obtain replacement parts.
Maintaining Your Dillon Powder Measure for Optimal Performance
Regular cleaning and lubrication are essential for maintaining the accuracy and longevity of your Dillon powder measure. Follow Dillon's recommended maintenance procedures outlined in your owner's manual. This includes periodic cleaning of all components, checking for wear and tear, and ensuring all screws and fasteners are tight.
By understanding the individual components and common issues, you can effectively troubleshoot and maintain your Dillon powder measure, ensuring safe and accurate reloading for years to come. Remember to always consult your Dillon press's specific manual for detailed instructions and safety precautions.
