Replacing a decapping pin on your RCBS reloading press is a crucial maintenance task that ensures the smooth and safe operation of your equipment. A worn or damaged decapping pin can lead to inconsistent case preparation, potentially causing misfires or damage to your press. This guide provides a step-by-step process for replacing your RCBS decapping pin, along with troubleshooting tips and preventative maintenance advice.
Identifying the Need for Replacement
Before diving into the replacement process, it's essential to identify whether your decapping pin actually needs replacing. Look for these signs:
- Bent or Damaged Pin: A visibly bent or broken decapping pin is the most obvious indicator of a problem.
- Loose Pin: If the pin feels loose or wobbly within its housing, it needs attention. This can lead to inconsistent decapping and potential damage to cases.
- Inconsistent Decapping: If you notice that some cases aren't being decapped properly, a worn or damaged pin is a likely culprit. This could result in primer pockets not being fully cleaned, leading to issues with reloading.
- Excessive Effort: If you're noticing significantly more effort is required to decapp cases than usual, this could be a sign of a worn or improperly seated decapping pin.
Tools and Materials Needed
Before you begin, gather the following tools and materials:
- Replacement RCBS Decapping Pin: Ensure you purchase the correct replacement pin for your specific RCBS press model.
- Small Screwdriver (likely a Phillips head): This will be needed to access the decapping assembly.
- Pliers (optional): Might be helpful for removing stubborn or stuck pins.
- Cleaning Solvent (optional): For cleaning the decapping assembly before reassembly.
- Shop Rag or Paper Towel: For cleaning up.
Step-by-Step Replacement Guide
The exact procedure might vary slightly depending on your specific RCBS press model (e.g., Rock Chucker, Partner Press, etc.), but the general steps remain consistent. Always consult your press's manual for model-specific instructions.
-
Disassemble the Decapping Assembly: Carefully remove the components surrounding the decapping pin. This typically involves removing screws or other fasteners securing the decapping assembly to the press. Refer to your press's manual for the correct procedure.
-
Remove the Old Decapping Pin: Once the assembly is disassembled, carefully remove the old decapping pin. Sometimes a gentle tap with a punch or even using your fingers is sufficient. If it's stuck, use pliers carefully to avoid damaging the surrounding components.
-
Clean the Assembly: Use a cleaning solvent and a rag or paper towel to clean the decapping assembly, removing any debris or old lubricant. This ensures a smooth installation of the new pin and helps prevent future issues.
-
Install the New Decapping Pin: Carefully insert the new decapping pin into its housing. Ensure it's seated correctly and firmly.
-
Reassemble the Decapping Assembly: Carefully reassemble the decapping assembly, following the reverse order of disassembly. Double-check that all screws and fasteners are tightened securely.
-
Test the Press: Before beginning a full reloading session, test the press with a few dummy cases to ensure the decapping process is working smoothly.
Preventative Maintenance
Regular maintenance can extend the lifespan of your decapping pin and your entire reloading press. Consider these preventative measures:
- Lubrication: Regularly lubricate the decapping assembly with a high-quality reloading lubricant.
- Inspection: Periodically inspect your decapping pin for signs of wear or damage.
- Case Prep: Ensure your cases are properly cleaned and sized before decapping to reduce stress on the decapping pin.
Troubleshooting
If you encounter problems during the replacement process, consult your RCBS press's manual or contact RCBS customer support for assistance. Incorrectly installing the decapping pin can damage your press or lead to unsafe reloading practices.
This guide provides a comprehensive overview of replacing an RCBS decapping pin. Remember that safety is paramount when reloading ammunition. Always adhere to safe reloading practices and consult your press's manual for specific instructions. By following these steps and practicing preventative maintenance, you can ensure your RCBS press operates efficiently and safely for years to come.
