Why Handloaders Choose the Lee Precision Breech Lock Pro Shell Plate #21

For reloaders using the versatile Lee Breech Lock Pro progressive press, a dedicated shell plate is indispensable. Unlike single-stage presses where a shell holder is often integrated directly into the ram, a progressive press requires a rotating shell plate that indexes cases through multiple stations. The Lee Precision Shell Plate #21 is engineered with specific pocket dimensions to accommodate the rim and base of 6.8 SPC and .224 Valkyrie cases, ensuring they are securely held, correctly aligned with the dies, and smoothly advanced from one operation to the next without slippage or misalignment.

Key Benefits and Unique Value Propositions:

• Optimized Case Retention: The precise machining of the #21 shell plate's pockets ensures a firm, yet non-marring grip on the case rim. This prevents cases from wobbling, tilting, or coming loose during aggressive operations like sizing or bullet seating, which is crucial for maintaining concentricity and preventing frustrating stoppages.
• Seamless Progressive Press Integration: Designed exclusively for the Lee Breech Lock Pro progressive press, this shell plate ensures smooth, reliable indexing. Each click of the indexing rod advances the plate by one station, presenting the case perfectly to the next die without requiring manual adjustment.
• Durability for High-Volume Reloading: Constructed from robust materials, the #21 shell plate is built to withstand the repetitive forces of high-volume ammunition production. It resists wear and deformation, providing a long service life even under demanding conditions.
• Enhanced Reloading Efficiency: By providing consistent case presentation, the shell plate minimizes errors and maximizes the speed at which you can produce finished rounds. This translates directly into more ammunition in less time, freeing you up for more shooting or other pursuits.

Decoding the Calibers: 6.8 SPC and .224 Valkyrie

The Lee Precision Shell Plate #21 is specifically designed for two modern and increasingly popular rifle cartridges: the 6.8 SPC (Special Purpose Cartridge) and the .224 Valkyrie. Understanding why these calibers are favored by reloaders helps illuminate the importance of having the right tools for them.

The 6.8 SPC: A Balanced Performer

The 6.8 SPC was developed as a medium-range military cartridge to improve upon the terminal ballistics of the 5.56x45mm NATO. It offers a significant increase in energy and stopping power, making it an excellent choice for hunting medium game (like deer and hogs) and for defensive applications. Its moderate recoil and AR-15 platform compatibility have also made it popular among sport shooters.

Why Reload 6.8 SPC?

• Cost Savings: Factory 6.8 SPC ammunition can be expensive due to its specialized nature. Handloading significantly reduces the per-round cost, allowing for more practice and development.
• Performance Optimization: Reloaders can fine-tune loads for specific bullet weights, powder types, and primer combinations to achieve optimal accuracy from their rifle. This is critical for hunters who demand precision for ethical kills and for competitive shooters seeking an edge.
• Component Versatility: Access to a wide range of bullets, from light varmint rounds to heavier, more controlled expansion hunting bullets, allows for greater customization than factory offerings.

The .224 Valkyrie: Long-Range Precision in an AR Platform

The .224 Valkyrie is a relatively new cartridge, designed specifically for long-range precision shooting from an AR-15 platform. It achieves impressive ballistic coefficients and flat trajectories, rivalling cartridges traditionally requiring larger, heavier rifles. Its ability to effectively push heavy-for-caliber .22-caliber bullets makes it a formidable contender for distances out to 1,000 yards and beyond.

Why Reload .224 Valkyrie?

• Extreme Precision: The very nature of long-range shooting demands absolute consistency. Handloading allows for meticulous control over every variable – powder charge, bullet seating depth, neck tension – to shrink group sizes at extended distances.
• Economic Viability for Volume Shooting: Engaging in long-range practice consumes a lot of ammunition. Reloading drastically cuts down on the cost per round, making high-volume training more sustainable.
• Load Development for Specific Barrels: Every rifle barrel is unique. Reloaders can develop custom loads that "sing" with their particular barrel's harmonics, maximizing its inherent accuracy potential.
• Availability of Specialized Components: While factory .224 Valkyrie ammunition is available, handloaders gain access to a broader array of match-grade bullets and powders optimized for extreme long-range performance.

For both 6.8 SPC and .224 Valkyrie, the Lee Precision Breech Lock Pro Shell Plate #21 provides the crucial, consistent foundation needed for high-volume, precision reloading.

Getting Started: Integrating the Shell Plate into Your Reloading Setup

Installing and utilizing the Lee Precision Breech Lock Pro Shell Plate #21 is straightforward for anyone familiar with the Breech Lock Pro system.

Basic Installation Steps (Consult your press manual for detailed instructions):

1. Safety First: Ensure your press is clear of primers, powder, and any loaded ammunition. Always follow all safety guidelines for reloading.
2. Remove Existing Shell Plate (if any): Depending on your press model, this typically involves unscrewing a central bolt or retaining clip that holds the shell plate in place.
3. Clean the Arbor: Before installing the new shell plate, ensure the central arbor where the shell plate sits is clean and free of any debris or old lubricant.
4. Position the #21 Shell Plate: Carefully place the Lee Precision #21 shell plate onto the arbor, aligning the indexing notches with the corresponding pins on your press.
5. Secure the Shell Plate: Reinstall the central bolt or retaining clip, ensuring it is tightened sufficiently to hold the shell plate firmly without impeding its smooth rotation.
6. Function Check: Manually cycle the press a few times to ensure the shell plate indexes smoothly and without binding. Insert a couple of empty 6.8 SPC or .224 Valkyrie cases into the plate pockets to verify they seat correctly and are held securely.

Maintenance for Longevity:

• Keep it Clean: Regularly clean the shell plate, especially the case pockets, to prevent buildup of grime, powder residue, or carbon, which can affect case seating and indexing. A soft brush and solvent recommended for reloading equipment can be used.
• Lubrication: A light film of high-quality press lubricant on the underside of the shell plate and the central arbor can ensure smooth rotation and reduce wear. Avoid over-lubrication, which can attract contaminants.
• Storage: When not in use, store the shell plate in a clean, dry place to prevent rust or corrosion.

Common Questions and Considerations for Reloaders

When considering a shell plate like the Lee Precision Breech Lock Pro Shell Plate #21, reloaders often have specific questions.

• "Is this shell plate compatible with my XYZ press?"

  The Lee Precision Breech Lock Pro Shell Plate #21 (Product Number 90941) is specifically and exclusively designed for the Lee Breech Lock Pro progressive press. It is not compatible with other Lee press models (like the LoadMaster, Classic Turret, or single-stage presses) or presses from other manufacturers (e.g., Dillon, RCBS, Hornady). Always verify compatibility with your specific press model before purchase.

• "Why do I need a specific shell plate for each caliber?"

  A shell plate must precisely match the rim diameter and extractor groove dimensions of the cartridge case it's designed to hold. Cases like the 6.8 SPC and .224 Valkyrie, despite being relatively similar in overall length, have distinct base dimensions that require a dedicated shell plate for secure and accurate positioning through all reloading stages. Using an incorrect shell plate will lead to cases failing to seat, falling out, or misaligning, resulting in damaged cases, dies, or even press components.

• "Can this shell plate handle both large and small primers for these calibers?"

  The shell plate itself is responsible for holding the case. Primer seating is handled by the priming system of your Lee Breech Lock Pro press. Both 6.8 SPC and .224 Valkyrie cases typically use small rifle primers. The shell plate does not directly interact with the primer size, but ensures the case is correctly presented to the priming station.

• "What are the signs that my shell plate needs replacement?"

  While durable, shell plates can wear over extensive use. Signs of wear include:

  • Cases fitting loosely in the pockets, leading to wobbling or falling out.
  • Difficulty in indexing smoothly or binding during rotation.
  • Visible deformation, nicks, or burrs on the pocket edges.

  If you experience these issues, a replacement shell plate like the Lee Precision #21 can restore your press's performance.

• "How does this shell plate contribute to ammunition accuracy?"

  Consistency is paramount in accuracy. The shell plate ensures that each case is presented to the dies in the exact same orientation and position every time. This consistency translates into:

  • Uniform Sizing: Cases are resized straight and concentric.
  • Precise Bullet Seating: Bullets are seated straight into the case neck, minimizing runout, which is a major factor in accuracy.
  • Reliable Priming: Primers are seated to a consistent depth.

  Without a precise shell plate, inconsistencies would accumulate, degrading the quality and accuracy of your handloads.

Real-World Impact and User Outcomes

Consider the competitive shooter who demands sub-MOA accuracy from their .224 Valkyrie loads for long-range precision matches. The consistent case presentation offered by the Lee Precision Breech Lock Pro Shell Plate #21 is fundamental to achieving the ultra-low runout and uniform bullet seating necessary for success at extreme distances. Each case cycles flawlessly, allowing the reloader to focus on minute charge adjustments and seating depth instead of wrestling with misfed brass.

Imagine the avid hunter who relies on their custom 6.8 SPC ammunition for ethical harvests. The ability to produce a high volume of consistent, reliable rounds means more time at the range fine-tuning their skills and less time worrying about ammunition quality. The shell plate ensures every cartridge is built to the same exacting standards, providing confidence when that once-in-a-lifetime shot presents itself.

For the cost-conscious hobbyist, the efficiency gains from a reliable shell plate translate directly into financial savings. Faster, smoother reloading means more finished rounds per hour, maximizing the value of their time and components. It eliminates frustrating pauses and errors that can waste expensive primers, powder, and bullets.
