Product Overview

The RCBS Primer Plug/Sleeve/Spring assembly is a replacement part for RCBS reloading presses, specifically designed for seating small primers. It consists of three main components:

• Primer Plug: The component that directly contacts and seats the primer into the primer pocket.
• Primer Sleeve: Guides the primer plug and primer into position.
• Spring: Provides the necessary tension and return action for the primer plug and sleeve during the priming stroke.

Setup and Installation

1. Disassembly (if replacing): If replacing an existing primer assembly, carefully remove the old primer plug, sleeve, and spring from your reloading press according to your press's instruction manual.
2. Inspection: Inspect the new RCBS Primer Plug/Sleeve/Spring assembly for any manufacturing defects or damage.
3. Lubrication (Optional): A very light coat of appropriate lubricant (e.g., dry film lubricant) can be applied to the exterior of the primer sleeve to ensure smooth operation, if recommended by your press manufacturer. Avoid getting lubricant on the primer seating surface.
4. Installation: Insert the spring onto the primer sleeve, then place the primer plug into the top of the sleeve. Refer to your specific RCBS reloading press manual for detailed instructions on how to correctly install this assembly into the priming arm or station of your press. Ensure all components are seated properly and securely.
5. Function Check: Manually cycle the press arm to verify that the primer assembly moves freely and returns to its original position without binding.

Operating Instructions

This primer assembly is used in conjunction with your reloading press to seat small primers into cartridge cases. Always follow the specific operating procedures outlined in your reloading press manual.

1. Primer Selection: Ensure you are using small primers that are compatible with your cartridge and the RCBS Small Primer Plug/Sleeve/Spring.
2. Case Preparation: Prepare your cartridge cases by cleaning, resizing, and decapping them as necessary. Ensure the primer pockets are clean and free of debris.
3. Priming Process:
   • Place a single small primer into the primer cup or on the priming arm, ensuring it is oriented correctly (anvil up).
   • Position the prepared cartridge case over the primer plug.
   • Slowly and steadily operate your reloading press handle to bring the primer plug into contact with the primer, seating it into the primer pocket of the case.
   • Apply firm, consistent pressure until the primer is fully seated, flush with or slightly below the case head. Avoid excessive force, which can deform the primer or case.
   • Retract the press handle to complete the priming stroke.
4. Inspection: Visually inspect each primed case to confirm the primer is seated correctly and not crushed or tilted.

Maintenance

Regular maintenance ensures optimal performance and extends the life of your primer assembly.

• Cleaning: Periodically clean the primer plug, sleeve, and spring to remove primer residue, carbon, and other debris. Use a soft cloth or brush. Avoid harsh chemicals that could damage the finish or material.
• Inspection: Regularly inspect the primer plug for wear, especially on the seating surface. Check the spring for any signs of fatigue, bending, or breakage. Ensure the sleeve is not bent or obstructed.
• Replacement: If any component shows significant wear, damage, or fails to function correctly, replace the entire assembly with a genuine RCBS part (Model 9553).
• Storage: Store the primer assembly in a clean, dry environment when not in use.
