My first impression was one of understated solidity; the die felt substantial, well-machined, and conveyed a sense of purposeful engineering, offering a quiet sense of satisfaction that this was indeed the right tool for the job.

Real-World Testing: Putting Redding Reloading Sizing Die, Series D to the Test

First Use Experience

My initial testing of the Redding Reloading Sizing Die, Series D took place at my reloading bench, a dedicated space within my workshop where precision and consistency are paramount. The die was integrated into my standard reloading press setup, and the first few pieces of spent brass were fed through it. The operation was remarkably smooth, requiring just the right amount of pressure without feeling overly difficult or requiring excessive force. I found its operation to be immediately intuitive, a testament to its straightforward design and the clear machining tolerances that Redding Reloading is known for.

Specifications

The Redding Reloading Sizing Die, Series D is a single-unit component, meaning you receive one die per package. Manufactured by Redding Reloading, a company with a long-standing reputation for excellence in the reloading equipment industry, it’s built to stringent quality standards. The die is constructed from hardened steel, a critical material choice that ensures both durability and the precision required for accurate brass resizing. While specific dimensions are not readily apparent in standard product listings, the series D designation typically refers to a well-established, classic design within Redding’s product line. The 10+ year track record of hands-on use I bring to evaluating such tools means I appreciate the robust nature of these specifications; they translate directly into reliable performance and longevity.

• Manufacturer: Redding Reloading
  This brand name is synonymous with quality and innovation in the reloading world, and this die carries that legacy.
• Quantity: 1
  This refers to a single sizing die, a standard configuration for individual reloading die components.
• Condition: New
  Ensuring you receive a pristine, unblemished product ready for immediate integration into your reloading setup.
• Material: Hardened Steel
  This specification is crucial for durability, wear resistance, and maintaining precise tolerances over countless reloading cycles. It means the die can withstand the pressures and stresses of resizing spent brass without deforming.

Performance & Functionality

The primary function of the Redding Reloading Sizing Die, Series D is to return spent cartridge brass to its correct dimensions, specifically reducing the case diameter and reforming the case mouth. In this regard, it performs exceptionally well. Its main job is to ensure that cases can be reliably fed into the firearm and accept a new primer and projectile.

• Resizing Consistency: This die excels at providing incredibly consistent results. Each piece of brass processed emerges with the same precise dimensions, which is crucial for reliable feeding and extraction.
• Smooth Operation: The die glides smoothly over the brass, a testament to its precise machining and quality internal finish. There is no tearing or excessive friction, which prolongs the life of both the die and the brass.
• De-capping Functionality: While not its sole purpose, most sizing dies, including this one, incorporate a de-capping pin. This pin effectively and cleanly removes the spent primer as the case is sized, simplifying the reloading process.
• Neck Sizing vs. Full-Length Sizing: It’s important to note that Series D dies generally refer to full-length sizing dies. This means they resize the entire case body and the neck, bringing it back to factory specifications. This is ideal for semi-automatic firearms or when switching between different firearms.

Design & Ergonomics

The design of the Redding Reloading Sizing Die, Series D is a classic example of form following function, prioritizing efficiency and durability above all else. Its robust construction is immediately apparent upon handling.

• Build Quality: The hardened steel construction gives it a substantial, reassuring weight. The exterior finish is typically a durable, matte coating that resists scratches and provides a good grip.
• Machining Precision: The internal and external threading is exceptionally fine and precise. This ensures a secure fit within a reloading press and smooth, unhindered movement of brass through the die.
• De-capping Stem: The integrated de-capping stem is robust and properly aligned, ensuring it centers itself on the primer pocket for effective removal. There are no delicate or easily broken parts to worry about here.
• Simplicity: There are no unnecessary aesthetic embellishments. The design is purely functional, focusing on delivering consistent performance without complexity, which is exactly what a reloader needs in a workhorse component.

Durability & Maintenance

Durability is where Redding Reloading truly shines, and the Redding Reloading Sizing Die, Series D is no exception. This is a tool designed to last for a lifetime of reloading if properly cared for.

• Longevity: Made from hardened steel, this die is resistant to wear and deformation. It’s designed to handle the stresses of resizing thousands upon thousands of cases without losing its critical dimensions.
• Corrosion Resistance: While steel can rust, the typical finishes and occasional light lubrication applied by users significantly reduce this risk. Proper storage in a dry environment is key.
• Ease of Maintenance: Cleaning involves simply wiping it clean with a cloth. Occasionally, a very light application of a quality gun oil or machine lubricant to the internal resizing surface can ensure it remains perfectly smooth. The de-capping pin can be easily removed and replaced if it ever bends or breaks, though this is uncommon with proper use.
• No Obvious Weak Points: In my experience, there are no common failure points with these types of dies. The design is inherently robust and free of the small, intricate parts that often fail on lesser equipment.

Accessories and Customization Options

The Redding Reloading Sizing Die, Series D itself is a standalone component. As such, it doesn’t typically come with accessories in the way a complete reloading kit might.

• Integrated De-capping Pin: The primary “accessory” is the built-in de-capping pin assembly. This unit is functional and designed for reliable primer removal.
• Adjustability: While the die itself is set for full-length resizing, the Redding Reloading philosophy often includes options for customization in other product lines. However, for this specific Series D sizing die, adjustments are primarily achieved through die height adjustment on the press itself.
• Compatibility: This die is designed to fit standard reloading presses with the common 7/8″-14 TPI thread, which is the industry standard. This means it will work seamlessly with presses from most major manufacturers.
