Hornady powder measures are renowned for their accuracy and reliability in reloading, but like any precision instrument, they require proper maintenance and occasional part replacement. Understanding the various components and their functions is crucial for ensuring optimal performance and preventing costly mistakes. This guide provides a detailed overview of Hornady powder measure parts, common issues, and troubleshooting tips.
Key Components of a Hornady Powder Measure
Hornady offers several powder measure models, each with slightly different components, but the core elements remain consistent. Let's examine the primary parts:
1. Hopper:
The hopper is the topmost component, responsible for holding the powder. Its size varies depending on the model, impacting the amount of powder you can load before refilling. Inspect the hopper regularly for any cracks or damage that could compromise powder flow.
2. Powder Drop Tube:
This tube connects the hopper to the metering mechanism, delivering powder to the metering system. Ensure this tube is free from obstructions and properly seated. A damaged or misaligned drop tube can lead to inconsistent powder charges.
3. Metering System:
This is the heart of the powder measure. The specific design varies between Hornady models (e.g., case activated, auto-indexing), but the core function remains consistent – accurately metering the powder charge. Common metering system components include:
- Micrometer Adjustment: Allows for precise adjustment of the powder charge weight. Regular cleaning and careful adjustments are vital to maintain accuracy.
- Measure Chamber/Housing: This component houses the mechanism that meters the powder. Keep it clean and free from powder build-up.
- Rotor/Disc (for some models): A rotating component that dispenses the powder. Its condition significantly affects metering accuracy. Examine it for wear and tear.
- Case Activation Mechanism (for case activated models): This component triggers the powder drop when a cartridge case is presented.
4. Powder Drop Mechanism:
This mechanism releases the metered powder charge into the case. Ensure it functions smoothly and reliably. Problems here can lead to inaccurate powder charges.
5. Base/Mount:
The base secures the powder measure to the press. A securely mounted powder measure is crucial for consistent performance and safety.
Troubleshooting Common Issues
Understanding common problems and their associated parts can save you time and frustration. Here are some scenarios:
Inconsistent Powder Charges:
- Check the metering system: Look for obstructions, powder build-up, or wear and tear on the rotor/disc (if applicable).
- Inspect the micrometer adjustment: Ensure it's properly calibrated.
- Clean the entire measure thoroughly: Powder residue can significantly affect accuracy.
Powder Bridge Formation in the Hopper:
- Ensure the hopper is properly filled: Overfilling can lead to bridging.
- Use a powder funnel: A funnel helps to fill the hopper consistently and prevent bridging.
Powder Measure Not Dropping Powder:
- Inspect the powder drop mechanism: Make sure there are no obstructions.
- Check the case activation mechanism (if applicable): Ensure it’s properly functioning.
Maintaining Your Hornady Powder Measure
Regular maintenance is essential to ensure long-term accuracy and reliability:
- Clean after each reloading session: Remove powder residue to prevent build-up.
- Inspect parts regularly: Check for wear, damage, or loose components.
- Lubricate moving parts (as needed): Refer to your Hornady powder measure manual for lubrication recommendations.
- Replace worn or damaged parts: Order replacement parts directly from Hornady or an authorized dealer.
This guide provides a solid foundation for understanding your Hornady powder measure’s parts and maintaining its optimal performance. Remember to consult your specific Hornady powder measure manual for detailed instructions and troubleshooting advice. Accurate reloading depends on well-maintained equipment, and this understanding is your first step towards safe and consistent results.
