Why Neck Sizing? The Foundation of Precision Handloading

Before diving into the specifics of the Lee Collet Die, it’s crucial to understand the fundamental benefits of neck sizing versus full-length sizing. Full-length sizing reshapes the entire cartridge case, including the body and shoulder, to ensure it fits into any chamber. While necessary for ammunition fired in multiple rifles or for cases that have been fired too many times in a semi-automatic action, it introduces more working of the brass, which can lead to premature case fatigue and reduced brass life.

Neck sizing, on the other hand, only resizes the neck of the cartridge case. This method is ideal for ammunition that will be fired exclusively in the same rifle from which the brass originated. By only working the neck, the case body fire-forms precisely to your rifle's chamber, creating a perfect fit that contributes significantly to accuracy. This minimal working of the brass greatly extends the life of your valuable cartridge cases, allowing for many more reloading cycles. For the .25-06 Remington, a popular caliber among long-range shooters and hunters due to its flat trajectory, maximizing brass life and consistency is paramount.

The Lee Collet Die Advantage: Unparalleled Consistency and Simplicity

The Lee Collet Neck Sizing Die stands apart in the world of reloading dies due to its unique design and operational benefits. Unlike traditional sizing dies that use an expander ball to set neck tension, the Lee Collet Die employs a set of four collet fingers that squeeze the case neck against a precision-ground steel mandrel. This innovative approach offers several distinct advantages that directly translate into improved ammunition performance and a more efficient reloading process:

• Zero Lubrication Required: One of the most significant benefits is the elimination of case lubrication. Traditional sizing dies require a thin layer of lube on each case to prevent it from sticking in the die. The collet design bypasses this messy, time-consuming step entirely, streamlining your reloading process. This is especially beneficial for high-volume reloaders or those who simply prefer a cleaner, more straightforward operation.
• Superior Neck Concentricity and Reduced Bullet Runout: Because the collet fingers press the case neck evenly around a hardened steel mandrel, the resulting neck tension is incredibly uniform. This method virtually eliminates bullet runout – the slight misalignment of the bullet relative to the case axis. Reduced runout is a critical factor in achieving superior accuracy, as it ensures the bullet enters the rifle's bore perfectly straight, leading to more consistent flight paths and tighter groups downrange.
• Extends Brass Life Dramatically: By only working the case neck and leaving the case body untouched, the Lee Collet Die minimizes brass fatigue. This preserves the integrity of the case shoulder and body, preventing premature cracks and splits. For reloaders of popular cartridges like the .25-06 Remington, where brass can be expensive, this extended lifespan translates into significant cost savings over time.
• Consistent Neck Tension, Regardless of Brass Thickness: The design ensures that the same, precise neck tension is applied consistently across all cases, regardless of slight variations in case neck wall thickness. This uniform tension is vital for consistent bullet release, which directly impacts muzzle velocity and, consequently, shot-to-shot accuracy.
• Ease of Use: The simplicity of operation makes it accessible even for novice reloaders, while its precision makes it a favorite among seasoned veterans. Just place the case in the shell holder, raise it into the die, and the collet fingers do the work.

How the Lee Collet Neck Die Works

Understanding the mechanics behind the Lee Collet Die helps illustrate its effectiveness. The die consists of a body, a collet, and a precision ground mandrel. When a fired case is raised into the die by the reloading press, the case neck surrounds the mandrel, which is held rigidly in place. As the ram continues upward, the collet fingers, housed within the die body, are forced inward, uniformly squeezing the case neck against the mandrel. This action perfectly resizes the neck to the desired diameter, establishing consistent neck tension for optimal bullet seating. When the ram is lowered, the collet fingers release, and the case is withdrawn. This elegant design eliminates the need for an expander ball, which can sometimes pull the case neck out of concentricity, a common issue with traditional sizing dies.

For the .25-06 Remington, ensuring this precise concentricity is particularly important for maintaining the ballistic advantages of this high-velocity cartridge. Every factor that contributes to consistent bullet flight path is amplified at longer ranges, making the collet die an essential tool for achieving pinpoint accuracy.

Who Can Benefit Most from the Lee Collet Neck Sizing Die?

The Lee Collet Neck Sizing Die is an ideal tool for several types of handloaders:

• Precision Target Shooters: For those chasing the smallest possible group sizes, the consistent neck tension and reduced runout offered by this die are invaluable. It helps eliminate one more variable in the complex equation of accuracy.
• Hunters: While often needing reliable rather than ultra-precise ammunition, hunters benefit from the consistent bullet seating and reliable feeding that a properly sized neck provides. The extended brass life is also a practical advantage for those who reload their hunting cartridges.
• Handloaders Seeking Maximum Brass Life: If you've invested in high-quality .25-06 Remington brass, this die will help you get the most reloading cycles out of it, saving money and reducing the frequency of brass preparation.
• Reloaders Who Prefer a Lube-Free Process: For anyone tired of dealing with sticky cases and the mess of case lube, the collet die offers a clean, efficient alternative.
• Beginner Reloaders: Its straightforward operation and elimination of a complex step (lubrication) make it an excellent choice for those just starting out in handloading, allowing them to focus on other critical aspects of the process.

Common Questions Answered

Does the Lee Collet Die really improve accuracy?
Yes, by significantly reducing bullet runout and ensuring exceptionally consistent neck tension, the Lee Collet Die directly contributes to improved accuracy. When the bullet leaves the case with minimal wobble and consistent grip, its flight path is more stable and predictable, leading to tighter groups. Many users report noticeable improvements in their shot-to-shot consistency and overall group sizes.

How much does it extend brass life?
While exact numbers vary based on brass quality, rifle chamber, and pressure levels, collet sizing can double or even triple the useful life of your brass compared to continuous full-length sizing. By only working the neck, the stress on the case body and shoulder is dramatically reduced, preventing the stretching and thinning that often leads to case head separation or splits. This is a significant economic benefit for .25-06 Remington reloaders.

Do I still need a full-length sizing die?
Typically, yes. While the Lee Collet Die is excellent for neck sizing, cases will eventually become difficult to chamber after several firings, as the case body expands slightly and the shoulder might creep forward. When this occurs, usually every 3-5 firings, you'll need to full-length size your brass to bring the shoulder back and resize the body for proper chambering. The ideal strategy is often to neck size with the collet die for most reloading cycles, and then full-length size only when necessary.

What about primer pockets and case trimming?
The Lee Collet Die does not affect primer pockets. You will still need to clean primer pockets, remove crimps (if applicable), and trim cases to length as part of your standard case preparation process. Trimming is essential to maintain consistent case length, which is critical for safety and accuracy.

Is it compatible with all reloading presses?
The Lee Collet Neck Sizing Die is designed to work with all standard reloading presses that accept 7/8"-14 dies, which includes virtually all single-stage, turret, and progressive presses from major manufacturers. It's a universal fit for your reloading setup.

Tips for Optimal Results

To get the most out of your Lee Collet Neck Sizing Die for .25-06 Remington, consider these tips:

• Clean Brass: Ensure your brass is clean before sizing. While no lube is needed, dirt or debris can scratch the die or case.
• Annealing (Optional but Recommended): Annealing your case necks every few firings can further extend brass life and promote even more consistent neck tension, especially for precision loads. This process softens the brass in the neck and shoulder area, making it more pliable.
• Proper Setup: Follow the instructions precisely for setting up the die. Proper adjustment is key to achieving optimal neck tension. Ensure the shell holder makes firm contact with the die base for consistent sizing.
• Monitor Case Length: Even with neck sizing, brass will stretch over multiple firings. Regularly check case length and trim as needed to maintain consistency and prevent excessive length, which can lead to dangerous pressure issues.
• Pair with Quality Components: The benefits of the Lee Collet Die are best realized when paired with high-quality bullets, primers, and powder. Precision reloading is a holistic endeavor.
