For avid shooters, particularly those who embrace the raw power and long-range capabilities of the .338 Remington Ultra Magnum (.338 RUM) cartridge, the journey into handloading is often a natural progression. It’s a path chosen by individuals seeking unparalleled precision, significant cost savings, and the ultimate control over their ammunition's performance. Whether you're a seasoned long-range hunter aiming for ethical, one-shot takedowns or a competitive shooter striving for sub-MOA groups, achieving consistent, high-quality ammunition is paramount. This is where specialized tools, like the Lee Pacesetter 2-Die Set for .338 RUM, become indispensable.

This detailed guide is crafted for anyone looking to unlock the full potential of their .338 RUM firearm by producing custom-tailored ammunition. It addresses the common challenges faced by reloaders – from ensuring proper case dimensions to achieving precise bullet seating – and highlights how the right equipment can transform your reloading process into a rewarding and highly effective endeavor. If you’ve ever wondered about the best way to optimize your .338 RUM loads, reduce ammunition costs, or improve your rifle's accuracy, you’re in the right place.

Why Handload .338 RUM Ammunition?

The .338 RUM is an incredibly potent cartridge, renowned for its flat trajectory, high muzzle velocity, and formidable energy retention, making it a favorite for large game hunting and extreme long-range shooting. However, factory ammunition for such specialized cartridges can be expensive and may not always offer the precise characteristics desired for a particular rifle or shooting discipline. Handloading solves these issues by offering:

• Significant Cost Savings: The initial investment in reloading equipment is quickly recouped, as component costs are often a fraction of factory loaded ammunition prices, especially for magnum cartridges. This allows for more practice and experimentation.
• Enhanced Accuracy and Consistency: Factory ammunition is produced to general specifications. Handloading allows you to fine-tune every aspect of your cartridge – from bullet selection and powder charge to seating depth – creating loads perfectly matched to your rifle's unique harmonics and preferences. This often translates directly into tighter groups and improved downrange performance.
• Customization for Specific Applications: Whether you need a load optimized for a specific bullet weight for big game hunting, or a highly consistent load for competitive long-range precision, handloading provides the flexibility to achieve it. You can experiment with different powders, primers, and bullet types to find the ideal combination.
• Extended Brass Life: Proper sizing and care during the reloading process can significantly extend the life of your brass cases, further enhancing cost efficiency and consistency.

Introducing the Lee Pacesetter 2-Die Set for .338 RUM (Product 90927)

At the heart of any successful reloading operation is a set of high-quality dies. The Lee Pacesetter 2-Die Set, specifically engineered for the .338 RUM (Product 90927), provides the fundamental tools necessary for precise and consistent ammunition production. Lee Precision is a long-standing, reputable brand in the reloading community, known for offering excellent value and innovative designs. This particular die set is designed to meet the rigorous demands of reloading powerful magnum cartridges like the .338 RUM, ensuring that each step of the process contributes to a superior end product.

What's included in the Lee Pacesetter 2-Die Set for .338 RUM (Product 90927)?

This essential set typically includes:

1. Full Length Sizing Die: This die performs several critical functions. It reshapes the fired brass case back to factory specifications, ensuring it will chamber reliably in your rifle. Simultaneously, it decaps the spent primer from the case. The design of Lee's sizing dies aims for minimal resistance and smooth operation, making the resizing process efficient and less fatiguing. This critical step sets the foundation for consistent cartridge dimensions.
2. Bullet Seating Die: This die is used to precisely seat the new bullet into the resized and primed case, and it also includes a built-in crimping feature. The depth at which the bullet is seated is crucial for pressure, accuracy, and overall cartridge length. The Lee seating die allows for fine adjustments, enabling reloaders to achieve specific cartridge overall lengths (COAL) tailored to their rifle and chosen bullet. The integrated crimp helps secure the bullet, especially important for magnum cartridges subject to heavy recoil, preventing bullet setback during feeding or under recoil.
3. Universal Shell Holder: A critical component that secures the brass case to your reloading press's ram, allowing it to be accurately presented to the dies.
4. Powder Dipper: A convenient tool for accurately measuring specific powder charges, particularly useful for getting started or for quickly verifying a known load.

Key Features and Benefits of Lee Pacesetter Dies for .338 RUM

When evaluating reloading dies, several factors distinguish a high-performing set. The Lee Pacesetter 2-Die Set (90927) excels in several key areas, providing tangible benefits for the .338 RUM reloader:

• Precision Machining for Accuracy: Lee dies are known for their precision manufacturing. The sizing die accurately restores fired brass to optimal dimensions, which is fundamental for consistent neck tension and reliable chambering. The bullet seating die offers fine control over seating depth, a critical factor for influencing barrel harmonics and achieving peak accuracy. This level of precision helps reloaders achieve tighter groups downrange.
• Durable Construction: Built from hardened steel, these dies are designed to withstand the rigors of high-volume reloading, providing years of reliable service. Their robust construction ensures they maintain their dimensional integrity, contributing to consistent ammunition over time.
• Ease of Use: Lee Precision is committed to user-friendly design. The Pacesetter dies are straightforward to set up and operate on most standard reloading presses, making them suitable for both novice and experienced reloaders. Clear instructions accompany the set, guiding users through the initial setup process.
• Integrated Crimp Feature: The bullet seating die in the Pacesetter set often includes a built-in roll crimp. This feature is particularly beneficial for magnum cartridges like the .338 RUM, where heavy recoil can potentially cause bullets to shift or "setback" in the case. A proper crimp secures the bullet firmly, ensuring consistent pressure and preventing bullet movement.
• Value Proposition: Lee Precision consistently delivers high-quality reloading equipment at an accessible price point. The Pacesetter 2-Die Set provides an excellent entry point into precise .338 RUM reloading without compromising on performance or durability. This makes it an ideal choice for anyone looking to maximize their budget while still acquiring reliable tools.

Common Questions About .338 RUM Reloading and the Lee Pacesetter Set

• Is reloading .338 RUM cartridges worth the effort? Absolutely. Given the cost of factory .338 RUM ammunition, handloading offers substantial long-term savings. More importantly, it provides the ability to craft ammunition precisely tuned to your rifle, often leading to significantly improved accuracy and performance over off-the-shelf options. For hunters and precision shooters, this level of control can be the difference between a good shot and a perfect one.
• How do these dies specifically improve accuracy for .338 RUM? The full-length sizing die ensures uniform case dimensions, which contributes to consistent neck tension on the bullet. Consistent neck tension is vital for uniform bullet release from the case. The bullet seating die allows for precise control over seating depth, which can be optimized for your rifle's chamber and specific bullet choice to find its "sweet spot" for accuracy. This meticulous control over critical dimensions directly impacts shot-to-shot consistency and, ultimately, group size.
• Are the Lee Pacesetter dies (Product 90927) suitable for beginners in .338 RUM reloading? Yes, they are an excellent choice for beginners. Lee's dies are designed for straightforward operation, and the Pacesetter series provides all the essential functions needed for producing high-quality ammunition. While .338 RUM is a powerful cartridge requiring attention to detail, the intuitive nature of these dies, coupled with adherence to reloading manuals, makes the process manageable for those new to handloading.
• What additional equipment will I need to start reloading .338 RUM with this die set? While the dies are crucial, you'll also need a sturdy reloading press (single-stage, turret, or progressive), a shell holder (included in this set), a reliable powder measure, a precise scale for weighing powder charges, primers, gunpowder, bullets, and a reloading manual. Other useful accessories include case lubes, case trimmers, deburring tools, and a primer pocket cleaner.

Maximizing Your Reloading Potential with Lee Pacesetter Dies

To achieve the best results with your Lee Pacesetter dies and .338 RUM reloading, consider these practices:

• Follow Reloading Manuals Diligently: Always consult multiple, reputable reloading manuals. They provide tested load data, safety guidelines, and step-by-step instructions. Never exceed maximum recommended powder charges.
• Lubricate Cases Properly: For full-length sizing, especially with larger rifle cases like the .338 RUM, proper case lubrication is essential to prevent cases from sticking in the die and to ensure smooth operation.

• Cleanliness is Crucial: Keep your dies, press, and work area clean. Debris can scratch dies or cases, leading to inconsistent ammunition.
• Start Low and Work Up: When developing new loads, always start with the minimum recommended powder charge and gradually increase it in small increments while observing pressure signs and accuracy.
