# Elevate Your Reloading Precision with the Lee Precision Lube & Size Kit (MPN: 90036, UPC: 734307900366)

For the dedicated handloader, the pursuit of perfection in ammunition crafting is an ongoing journey. Whether you're an experienced reloader looking to maximize your cast bullet performance or a newcomer delving into the rewarding world of casting your own projectiles, the Lee Precision Lube & Size Kit is an indispensable tool. This comprehensive kit provides a streamlined, efficient, and highly effective method for preparing cast bullets, ensuring they meet the precise dimensions and lubrication requirements for optimal accuracy and reliable chambering.

At its core, the Lee Lube & Size Kit addresses critical steps in the cast bullet preparation process: sizing, lubricating, and gas check application. These steps are paramount for several reasons, directly influencing bullet performance, barrel longevity, and overall shooting enjoyment. Why are these steps so important, and what problems does this kit solve for the reloader?

The Imperative of Bullet Sizing and Lubrication

Cast bullets, while offering significant cost savings and the satisfaction of DIY craftsmanship, rarely emerge from the mold at the exact, consistent diameter required for optimal performance. Variations can occur due to mold wear, alloy composition, casting temperature, and even cooling rates. A bullet that is too large may lead to excessive pressure, difficult chambering, or deformation upon firing. Conversely, an undersized bullet can result in gas cutting (where hot gases bypass the bullet, eroding the bore), leading to poor accuracy and excessive leading in the barrel.

This is where precise bullet sizing becomes crucial. The Lee Precision Lube & Size Kit utilizes a highly accurate push-through sizing die that uniformly reduces the bullet's diameter to the desired specification. This ensures consistent bullet-to-bore fit, a fundamental requirement for achieving tight groups and predictable ballistics.

Equally vital is proper bullet lubrication. Cast bullets, unlike jacketed projectiles, rely on a protective layer of lubricant to reduce friction as they travel down the bore. This lubrication prevents leading, mitigates heat buildup, and helps seal the bore to improve gas efficiency. Without adequate lubrication, lead can quickly deposit in the rifling, degrading accuracy, increasing wear on the barrel, and making cleaning a laborious task. The Lee kit facilitates the application of lubricant simultaneously with the sizing process, streamlining your workflow and ensuring every bullet is properly prepared.

Furthermore, for higher velocity loads or specific bullet designs, gas checks are essential. These small copper or aluminum cups are crimped onto the base of a lead bullet to protect its base from the hot propellant gases, preventing deformation and leading at the bullet's rear. The Lee Lube & Size Kit is ingeniously designed to seat and crimp these gas checks seamlessly as part of the sizing operation, adding another layer of efficiency and precision to your bullet preparation.

Unpacking the Lee Precision Lube & Size Kit: What's Included and How It Works

The Lee Precision Lube & Size Kit is renowned for its simplicity, effectiveness, and robust construction. Designed for use with any standard single stage reloading press that accepts 7/8 x 14 threads, it integrates smoothly into most reloading setups. This universal compatibility makes it an accessible choice for a wide range of reloaders, from those just starting out to seasoned veterans looking for an efficient sizing solution.

Each kit contains the essential components you need to begin sizing and lubricating your cast bullets:

• Sizer Die: This is the heart of the system. Crafted from durable steel, the sizer die features standard 7/8 x 14 threads, allowing it to screw directly into the die station of your single stage press. Its innovative design allows bullets to be pushed through nose first, eliminating the need for separate nose punches for different bullet profiles. This universal approach simplifies your inventory and setup.
• Sizer Punch: Replacing the shell holder in your press's ram, the sizer punch is specifically designed to push the bullet smoothly through the sizer die. Its precise fit ensures consistent sizing pressure and uniform results with every cycle.
• Sizer Box/Container: As bullets are pushed through the die, they exit into a special container that captures the sized and lubricated projectiles. This clever collection system keeps your workspace tidy and your finished bullets organized, ready for loading.
• Detailed Instructions: Lee Precision provides clear, concise instructions to guide you through the setup and operation of the kit, ensuring a straightforward and successful experience, even for first-time users.

How the Push-Through Sizing System Works:

1. Mounting the Die: Screw the sizer die into the top of your single stage press, similar to how you would install any other resizing or seating die.
2. Inserting the Punch: Place the specific sizer punch into the ram of your press, replacing the standard shell holder.
3. Applying Lubricant: For optimal results, apply Lee Liquid Alox (sold separately) to your cast bullets before sizing. A thin, even coat is typically applied by tumble lubing the bullets.
4. Sizing the Bullet: Place a cast bullet (base down, nose up) onto the sizer punch. As you actuate the press handle, the punch pushes the bullet up and into the sizer die. The bullet is forced through the precision-ground aperture, uniformly reducing its diameter to the desired size while simultaneously applying a fresh layer of lubricant (if using Lee Liquid Alox, which adheres effectively during this process) and crimping any gas checks onto the bullet's base.
5. Collecting Sized Bullets: The sized bullet exits the top of the die and falls into the integrated collection container, ready for your next reloading step.

This push-through method offers several advantages: it's clean, efficient, and provides exceptional consistency. By sizing the bullet from the base to the nose, it ensures uniformity along the entire bullet body.

Optimizing Performance: Tips for Using Your Lube & Size Kit

While the Lee Precision Lube & Size Kit is inherently simple to use, a few best practices can help you achieve the best possible results and maximize its lifespan:

1. Select the Correct Sizing Diameter: This is paramount. For cast bullets, it's generally recommended to select a sizing kit that is .001" larger than your firearm's groove diameter. For example, if your .30 caliber rifle has a groove diameter of .308", you might opt for a .309" sizer die. Always slug your barrel to determine its true groove diameter for optimal bullet fit. Lee Precision offers these sizing dies in a wide array of calibers, allowing you to choose the perfect match for your needs.
2. Proper Lubrication is Key: While the kit facilitates lubrication, the quality and application of your lubricant matter. Lee Liquid Alox, sold separately, is specifically designed to work seamlessly with this system. Apply a thin, even coat to your cast bullets before sizing. Too much lubricant can be messy; too little will result in leading.
3. Clean Your Die Regularly: Over time, lubricant residue and microscopic lead particles can accumulate inside the sizer die. Periodically clean the die with a bore brush and a suitable solvent to maintain optimal performance and prevent scratching your bullets.
4. Inspect Your Press Setup: Ensure your single stage press is securely mounted and operating smoothly. Any wobble or inconsistency in the press can translate to variations in your sized bullets.
5. Consider Your Alloy: Different lead alloys have varying hardnesses. Softer alloys might require slightly different sizing techniques or lubricants than harder ones. Experimentation and observation are key to finding the perfect combination for your specific needs.
6. Safety First: Always wear appropriate personal protective equipment, including safety glasses, when reloading. Ensure good ventilation, especially when handling lead products.
