Addressing Common Reloading Challenges

• Inconsistent Case Sizing: Factory-fired brass, especially from semi-automatic firearms, can become significantly expanded and deformed. The Full Length Sizer Die meticulously returns cases to SAAMI specifications, ensuring reliable feeding and extraction in all firearms.
• Scratched Brass: Inferior dies can scratch or mar your brass during the sizing process, leading to premature case fatigue and reduced case life. The hand-polished interior of Redding dies completely eliminates this issue.
• Difficult Decapping: Crimped primer pockets or stubborn primers can bend or break decapping pins, halting your reloading process. The hardened steel decapping pin in this set is virtually indestructible, making even challenging decapping effortless.
• Excessive Case Neck Stretching: Expanding the case neck to accept a bullet can stretch and thin the brass, compromising its integrity and consistency. The elliptical expander design significantly reduces friction and stress on the case neck.
• Loose or Slipping Spindles: Traditional expander spindles can slip during adjustments, leading to inconsistent neck tension and frustrating interruptions. The innovative Zip Spindle design secures the spindle firmly in place.
• Inconsistent Bullet Seating Depth: Achieving precise and repeatable bullet seating depth is crucial for accuracy. The Seating Die's design, combined with Sure-Loc Lock Rings, ensures meticulous control over this critical dimension.
• Die Adjustment Challenges: Standard lock rings can mar threads or be difficult to adjust precisely. The Sure-Loc Lock Rings provide a secure, non-marring locking mechanism with convenient wrench flats.

Deep Dive into Engineering Excellence: Core Features and Benefits

The Redding 300 Blackout Full Length Die Set (UPC 090255563696) is packed with features that underscore Redding's commitment to precision and user convenience.

The Full Length Sizer Die: Foundation of Precision Reloading

This integral component is responsible for returning fired brass to its original dimensions, preparing it for subsequent reloading steps. Its design incorporates several proprietary Redding advancements:

• Full Length Sizing Capability: This die ensures that your 300 Blackout cases are resized along their entire length and shoulder, guaranteeing perfect chambering in any firearm, including AR-platform rifles where consistent feeding is paramount. This is especially vital for brass fired in different chambers or highly stretched cases.
• Hand Polished Interior: One of the most significant advantages for preserving your valuable brass. The interior of the sizing die is meticulously hand-polished to a mirror finish. This ultra-smooth surface virtually eliminates any friction or abrasion on the case wall during sizing, preventing scratches, gouges, and premature case fatigue. The result is prolonged brass life, allowing for more reloads per case, which translates directly into cost savings and consistent performance.
• Zip Spindle with Light Threads: A revolutionary feature that addresses the common frustration of expander spindles slipping during adjustments or operation. The Zip Spindle system incorporates a series of fine, light threads cut onto both the spindle and the spindle collet. This design allows for incredibly precise adjustments and, more importantly, securely locks the spindle in place once the desired setting is achieved. No more frustrating slips or inconsistent neck tension – just rock-solid stability and ease of use. This feature significantly enhances the reliability of your reloading process.
• Threaded Replaceable Expander Assembly: This design provides exceptional versatility and durability. The expander ball, which sizes the case neck internally, is threaded onto the decapping rod. This allows for easy removal and replacement if different expander sizes are needed for various bullet diameters or if the expander wears out over time. It simplifies maintenance and ensures long-term usability of the die.
• Elliptical Expander: A hallmark of Redding's advanced engineering, the elliptical expander design represents a significant improvement over traditional spherical expander balls. Its unique shape, gently tapered with an elliptical profile, dramatically reduces the force required to expand case necks. This reduction in friction minimizes case neck stretching and work-hardening, which are common causes of premature case cracking. It also makes the process of "necking up" brass (e.g., forming 300 Blackout from .223/5.56 cases) smoother and less stressful on the material. The result is superior concentricity, enhanced case life, and more consistent neck tension, all contributing to improved accuracy.
• Hardened Steel Decapping Pin: Designed for ultimate resilience, this decapping pin is manufactured from hardened steel, making it virtually impervious to bending, cracking, or breaking. This robust construction is particularly beneficial when decapping cases with tightly crimped primer pockets, a common occurrence with military surplus brass often used for 300 Blackout conversions. This feature eliminates frustrating work stoppages and the need for frequent decapping pin replacements, ensuring a smooth and uninterrupted reloading flow.

The Seating Die: Ensuring Bullet Uniformity

The seating die is responsible for inserting the bullet into the prepared case to the precise desired depth and, if applicable, applying a crimp. Redding's Seating Die is designed for unparalleled accuracy and consistency:

• Precision Bullet Seating: This die allows for highly accurate and repeatable bullet seating depth, a critical factor in achieving optimal accuracy and reliable feeding in your firearm. Consistent seating depth directly translates to consistent chamber pressures and muzzle velocities.
• Locking Retainer Spring: This innovative feature makes disassembly and cleaning of the seating die incredibly fast and easy. The spring can be removed in seconds, allowing for quick access to the internal components for cleaning, lubrication, or inspection. This simplifies maintenance and ensures your die remains in peak operating condition, preventing buildup that could affect seating consistency.

Sure-Loc Lock Rings: Unwavering Stability

Both the Full Length Sizer and Seating Die are secured with Redding's proprietary Sure-Loc Lock Rings. These rings are a significant upgrade over traditional locking mechanisms:

• Positive Locking Mechanism: Sure-Loc rings feature locking screws that engage the side of the die body, rather than directly contacting and potentially marring the threads of your reloading press or the die itself. This design ensures an incredibly secure hold, preventing the die from shifting or loosening during operation, even during high-volume reloading sessions.
• Wrench Flats: Each Sure-Loc ring is equipped with convenient wrench flats, allowing for easy and precise tightening or loosening with a standard wrench. This provides superior leverage and control compared to knurled rings, ensuring your dies are always perfectly set and secured. The non-marring design protects the threads of your valuable equipment.
