Operating Instructions
The primary function of the Hornady Shell Holder #6 is to securely hold cartridge cases during various reloading operations, such as sizing, decapping, priming, and seating bullets. Its precise fit ensures stability and alignment for consistent results.
General Use:
- Ensure the shell holder is clean and free of debris.
- Insert the shell holder into the appropriate slot on your reloading press or tool.
- Carefully align the cartridge case with the shell holder and push it firmly into place. The wide mouth and rounded edge are designed to facilitate this process.
- Proceed with your desired reloading operation (e.g., sizing, priming).
- After the operation, remove the case from the shell holder.
Advanced Application: Using with a Kinetic Bullet Puller (without collet)
In situations where the collet for your kinetic bullet puller is lost or damaged, a Hornady shell holder can be used as an effective alternative to pull bullets. This method allows you to continue reloading while awaiting a replacement collet.
Video 1: Demonstrates how to use a Hornady shell holder with a kinetic bullet puller when the collet is unavailable. This technique is useful for disassembling loaded cartridges for various reasons, such as correcting errors or recovering components.
Steps for using the shell holder with a kinetic bullet puller:
- Select the appropriate Hornady shell holder for the cartridge you intend to pull (e.g., a No. 16 shell holder for .223 Remington).
- Insert the case head of the loaded cartridge into the shell holder.
- Place the shell holder and cartridge assembly into the kinetic bullet puller's hammer body.
- Secure the assembly with the puller's cap.
- Proceed to strike the hammer against a firm surface to pull the bullet.
This method provides a secure grip on the case, allowing the kinetic energy to effectively separate the bullet from the case.
Maintenance
To ensure the continued precision and longevity of your Hornady Shell Holder #6, regular maintenance is recommended:
- Cleaning: After each use, wipe down the shell holder with a clean, dry cloth to remove any powder residue, lubricants, or debris. For stubborn grime, a mild solvent can be used, followed by thorough drying.
- Inspection: Periodically inspect the shell holder for any signs of wear, deformation, or damage. Pay close attention to the edges and internal surfaces that contact the cartridge case.
- Storage: Store the shell holder in a clean, dry environment to prevent rust and corrosion. A light coat of rust preventative oil can be applied if storing for extended periods.
Proper maintenance will help preserve the shell holder's precision and ensure smooth operation for many years.

While the Hornady Shell Holder #6 is designed for reliable performance, occasional issues may arise. Here are some common troubleshooting tips:
