Reloading your own ammunition is a rewarding process, offering precision and control over your cartridges. However, maintaining your reloading dies is crucial for consistent results and the longevity of your equipment. Dirty dies can lead to inconsistent bullet seating, inaccurate crimping, and even damage to your cases. This guide will walk you through the best methods and tools for cleaning your reloading dies, ensuring years of reliable performance.
Understanding Die Build and Contamination
Before we dive into cleaning methods, it's important to understand what you're dealing with. Reloading dies are typically constructed from hardened steel, often with various plated or coated finishes. The contaminants you'll encounter include:
- Case Lubricant: This is often the most significant culprit. Various lubricants, from lanolin-based to synthetic compounds, can build up on the die's surfaces.
- Powder Residue: Fine particles of gunpowder can embed themselves in the die's working parts.
- Metal Debris: Small particles of brass or lead can be shaved off during sizing and bullet seating.
- Rust: While less common with proper storage, rust can develop on exposed steel surfaces.
Essential Tools and Materials for Cleaning Reloading Dies
Gather these supplies before you begin cleaning your dies:
- Die Brush: A specifically designed die brush with brass or nylon bristles is ideal. Avoid steel brushes, as they can scratch the die's surface.
- Cleaning Solvent: A solvent like denatured alcohol or a dedicated gun cleaning solvent is excellent for dissolving case lubricant and powder residue. Avoid harsh chemicals that could damage the die finish.
- Cotton Patches or Cleaning Patches: These are crucial for wiping away loosened debris and solvent.
- Compressed Air: Useful for blowing away loose particles before and after cleaning.
- Microfiber Cloth: A soft microfiber cloth is perfect for a final polish after cleaning.
- Protectant (Optional): A light coat of oil or protectant can help prevent future rust and corrosion.
Step-by-Step Guide to Cleaning Reloading Dies
Follow these steps for thorough and effective die cleaning:
-
Disassembly (If Applicable): Some dies, particularly those with multiple components (e.g., seater dies with separate inserts), can be disassembled for easier cleaning. Consult your die manufacturer's instructions.
-
Initial Cleaning: Use compressed air to blow out any loose debris from the die's interior and exterior.
-
Solvent Application: Apply your chosen cleaning solvent to the die's surfaces, focusing on areas where lubricant or residue is most visible. Allow the solvent to dwell for a few minutes to help break down stubborn deposits.
-
Brushing: Use the die brush to scrub the die thoroughly. Pay close attention to the inside of the sizing die and the bullet seating die's cavity.
-
Wiping: Use cotton patches or a clean microfiber cloth to wipe away loosened debris and solvent. Repeat as needed until the die is clean.
-
Final Inspection: Examine the die carefully under good lighting. Repeat steps 3-5 if necessary.
-
Drying: Allow the die to air dry completely or carefully wipe it down with a clean, dry cloth.
-
Lubrication/Protection (Optional): Apply a very thin layer of gun oil or a suitable protectant to prevent rust and corrosion, especially if you store your dies in a humid environment.
Maintaining Your Dies: Preventing Future Build-up
Preventative maintenance will reduce the frequency of deep cleaning:
- Regular Cleaning: Clean your dies after every 500-1000 rounds.
- Proper Lubrication: Use a case lubricant designed for reloading and follow recommended application methods. Avoid over-lubrication.
- Case Preparation: Ensure your brass cases are clean and free of excessive debris before reloading.
- Storage: Store your dies in a dry, cool place to prevent rust.
By following these guidelines, you can maintain your reloading dies in optimal condition, ensuring consistent and accurate reloading for years to come. Remember, taking the time to clean your dies is a small investment that delivers significant returns in the form of superior ammunition and the protection of your valuable reloading equipment.
