Cleaning your 9mm brass is crucial for reliable reloading, and a Hornady tumbler can significantly streamline this process. This guide dives deep into using a Hornady tumbler specifically for 9mm brass, covering everything from media selection to achieving sparkling clean results.
Choosing the Right Hornady Tumbler
Hornady offers several models, each with varying capacities and features. The Hornady Lock-N-Load Case Tumbler is a popular choice for its robust build and efficient operation. However, the Hornady Lock-N-Load Universal Case Tumbler might be a better fit for those needing a larger capacity. Consider your reloading volume when making your selection. Larger tumblers are more efficient for high-volume shooters, while smaller models are perfectly adequate for occasional cleaning.
Selecting the Best Media for 9mm Brass
The media you choose directly impacts the cleanliness and shine of your 9mm brass. Several options exist:
1. Walnut Media:
- Pros: Gentle on brass, produces a good shine, relatively inexpensive.
- Cons: Can generate some dust, may not be as effective for heavily soiled cases. Best suited for cases with minimal fouling.
2. Corncob Media:
- Pros: Excellent cleaning power, removes stubborn fouling effectively, relatively inexpensive.
- Cons: Can be more abrasive than walnut, potentially causing minor scratches on delicate brass. Best for heavily soiled cases.
3. Plastic Media:
- Pros: Durable, long-lasting, generates minimal dust.
- Cons: Generally less effective at cleaning than walnut or corncob. Primarily useful for polishing already-clean cases.
For 9mm brass, a blend of walnut and corncob media often provides the best results. This combination leverages the cleaning power of corncob while mitigating its potential abrasiveness with the gentler walnut. Experimentation will determine the ideal ratio for your needs and desired finish.
The Tumbling Process: Step-by-Step Guide
-
Prepare Your Brass: Inspect your 9mm brass for any significant debris or damage. Remove any stuck bullets or primers. A quick rinse can help remove loose dirt before tumbling.
-
Add Media and Brass: Place your chosen media into the tumbler, filling it to the manufacturer's recommended level. Add your 9mm brass, ensuring it's not overcrowded. Overcrowding can hinder the tumbling action and lead to uneven cleaning.
-
Add Cleaning Solution: Use a suitable case cleaning solution. Hornady makes its own, but many other effective options exist. Follow the manufacturer's instructions regarding the correct amount of solution to add.
-
Tumbling Time: The tumbling time varies depending on the media used, the amount of brass, and the level of soiling. Start with a test run of a few hours and check the results. You may need to adjust the time for optimal cleaning.
-
Drying: Once the tumbling cycle is complete, remove the brass and let it dry completely. You can air dry it or use a low heat setting on a dryer to expedite the process. Avoid high heat, as it could damage the brass.
-
Post-Tumbling Inspection: Inspect your cleaned brass. If necessary, repeat the process for any cases that still appear dirty.
Tips for Optimal Results
-
Lubrication: Adding a small amount of lubricant to your media can help prevent excessive wear and tear on your brass.
-
Regular Media Replacement: Over time, the media will break down and lose its effectiveness. Replace your media periodically to maintain optimal cleaning results.
-
Avoid Overloading: Always follow the manufacturer's recommendations regarding the amount of brass to add to your tumbler.
-
Experimentation: Don't be afraid to experiment with different media types and ratios to find the perfect combination for your 9mm brass and desired level of cleanliness.
By following this guide, you can achieve consistently clean and shiny 9mm brass using your Hornady tumbler, ensuring your reloaded ammunition is ready for reliable performance at the range. Remember to always prioritize safety and follow all manufacturer guidelines.
