Master Your Reloading Precision with the Lee Powder Through Expanding Pistol Die for .40 S&W

Are you a dedicated handloader seeking to achieve unparalleled consistency and efficiency in your ammunition production? Do you grapple with issues like inconsistent powder charges, damaged bullet bases during seating, or the time-consuming process of separate powder dropping and case mouth flaring? For anyone serious about creating high-quality, reliable ammunition for their .40 S&W firearms, the Lee 90620 Powder Through Expanding Pistol Die offers an indispensable solution that streamlines your workflow and elevates your reloading results.

This precision-engineered die is specifically designed to address the critical steps of case mouth expansion and simultaneous powder charging, making it an essential component for both novice reloaders learning the ropes and seasoned enthusiasts optimizing their progressive press operations. It's the answer for those who prioritize both speed and accuracy, ensuring every round you load meets your exacting standards.

Why is the Expanding Die Critical for .40 S&W Reloading?

Before a bullet can be safely and accurately seated into a cartridge case, the case mouth must be slightly expanded or "flared." This seemingly simple step is profoundly important, especially for straight-walled pistol cartridges like the .40 S&W. Without proper case mouth expansion, several problems can arise:

• Bullet Damage: Forcing a bullet into an un-flared case mouth can shave lead from the bullet base, deform the bullet, or cause an off-center start. This leads to inconsistent bullet tension, poor accuracy, and potential safety issues.
• Case Damage: The delicate brass case mouth can be crushed, creased, or otherwise damaged if not properly prepared, rendering the case unusable and wasting valuable components.
• Inconsistent Seating: An improper flare can lead to varying bullet seating depths and inconsistent neck tension, both of which negatively impact ammunition reliability and accuracy.

The Lee Powder Through Expanding Die not only addresses these issues but takes efficiency to the next level by combining the expansion process with the powder charging step. This unique design is a hallmark of Lee Precision's innovative approach to reloading.

Unpacking the Features of the Lee 90620 Powder Through Expanding Pistol Die

The Lee 90620 Powder Through Expanding Pistol Die is meticulously crafted to serve the specific needs of .40 S&W reloaders. Its core strength lies in its ability to perform two crucial functions simultaneously, especially beneficial for those using progressive reloading presses, but still a significant advantage on single-stage setups.

• Integrated Powder Charging and Case Expansion: This is the flagship feature. As the case moves up into the die, the expander plug flares the case mouth to allow for smooth bullet seating. At the same time, the unique design allows a compatible Lee Auto-Disk Powder Measure or other Lee powder dispensing system to drop a precise powder charge directly into the case. This eliminates a separate powder dropping station, freeing up a valuable station on your progressive press and reducing the overall reloading cycle time.
• Precision-Machined Steel Construction: Built from high-quality steel, this die is designed for exceptional durability and longevity. It withstands the rigorous demands of high-volume reloading, maintaining its precise dimensions over countless thousands of rounds.
• Optimal Case Mouth Flaring: The expander plug is engineered to provide just the right amount of flare for .40 S&W cases. This prevents bullet damage during seating without overworking the brass, which can shorten case life.
• Versatile Compatibility: While optimized for Lee reloading presses and powder measures, this die features standard 7/8"-14 threads, making it compatible with most other major brands of reloading presses on the market. This ensures seamless integration into your existing reloading setup.
• Effortless Setup and Adjustment: Lee dies are known for their user-friendly design. The Powder Through Expanding Die is straightforward to set up and adjust, allowing you to quickly dial in the desired amount of case mouth flare and integrate your powder measure for precise charges.
• Designed for .40 S&W: Caliber-specific design ensures perfect fit and function for all .40 S&W cases, from a variety of manufacturers, maintaining the specific internal dimensions required for optimal performance with this popular pistol cartridge.

The Reloading Advantage: Benefits for Every Handloader

Investing in the Lee 90620 Powder Through Expanding Pistol Die for your .40 S&W reloading operations yields a multitude of practical benefits:

• Time Savings and Increased Output: By combining two steps into one, this die significantly reduces the number of operations per round. On a progressive press, this translates to dramatically faster reloading speeds, allowing you to produce more ammunition in less time. For example, what might take two separate pulls on a single-stage press becomes one fluid motion.
• Enhanced Ammunition Consistency: The integrated design helps ensure that every case is expanded to the same degree and receives a consistent powder charge, leading to more uniform ammunition. Consistent powder charges are paramount for reliable ignition, predictable recoil, and ultimately, tighter groups on target.
• Reduced Component Waste: Proper case mouth flaring prevents crumpled cases and damaged bullets, preserving your valuable components and lowering your overall cost per round. Are you tired of discarding brass due to improper seating? This die is your answer.
• Improved Safety: Accurate powder charging is a critical safety aspect of reloading. By delivering consistent and precise charges, this die helps minimize the risk of overcharges or squib loads, contributing to safer shooting experiences.
• Smoother Reloading Process: The seamless integration of powder drop and case expansion makes the overall reloading process more fluid and less prone to errors. It simplifies the setup and reduces potential points of failure.
• Extended Case Life: By providing just enough flare without overworking the brass, the die helps prolong the life of your .40 S&W cases, allowing for more reloading cycles before the brass fatigues.
• Cost-Effectiveness: Lee Precision is renowned for producing high-quality reloading equipment that offers exceptional value. This die is an affordable upgrade that delivers professional-grade results, allowing you to produce your own ammunition at a fraction of the cost of factory-loaded rounds. Think of the savings when you can reuse your brass multiple times and buy components in bulk.

How Does the Lee Powder Through Expanding Die Work?

The operation of this die is elegantly simple, yet profoundly effective:

1. Case Insertion: A spent, sized .40 S&W brass case is placed into the shell holder on your reloading press.
2. Upward Stroke: As the press ram moves upward, the case enters the die body.
3. Expansion: The internal expander plug engages the case mouth, gently flaring it open to the precise dimension required for smooth bullet seating.
4. Powder Dropping: Simultaneously, if a Lee Auto-Disk or Pro Auto-Disk powder measure (or other compatible Lee powder system) is attached to the top of the die, the movement of the case triggers the powder measure to dispense a pre-set amount of powder directly into the expanded case.
5. Downward Stroke: As the ram lowers, the now-flared and charged case is withdrawn from the die, ready for the next stage of bullet seating.

This synchronized operation is what makes the Lee Powder Through Expanding Die a favorite among reloaders who value efficiency and consistency.

Real-World Applications and Who Benefits Most

The Lee 90620 Powder Through Expanding Pistol Die is a game-changer for a variety of reloading scenarios and types of shooters:

• Competitive Shooters: For disciplines like USPSA, IDPA, or Steel Challenge where high round counts are common, the speed and consistency offered by this die are invaluable. Maintaining uniform ammunition helps achieve consistent results under pressure.
• Hobbyists and Enthusiasts: If you enjoy shooting your .40 S&W pistol frequently at the range, reloading your own ammunition significantly reduces costs. This die makes the process more enjoyable and less tedious.
• Beginner Reloaders: The simplified process, combining two steps, can make the initial learning curve of reloading much smoother. It helps build good habits of precision and attention to detail from the start. "How do I ensure consistent powder drops and avoid bullet damage?" This die is a direct answer.
