Mastering Ammunition Reloading: The Essential Lee Precision Classic Bullet Sizing Kit for Cast Bullets

For dedicated reloaders and shooting enthusiasts, the pursuit of precision and consistency in every cartridge is a lifelong endeavor. If you delve into the rewarding world of casting your own bullets, you quickly discover that achieving optimal performance requires more than just molten lead and a mold. It demands meticulous attention to detail, particularly in the critical steps of bullet sizing and lubrication. This is precisely where the Lee Precision Classic Bullet Sizing Kit, specifically designed for cast bullets, emerges as an indispensable tool. Available at DEGuns, this robust steel kit (UPC: 734307900557) empowers reloaders to produce high-quality, uniformly sized, and properly lubricated projectiles, leading to enhanced accuracy, reduced barrel leading, and significant cost savings.

Why Bullet Sizing and Lubrication Are Critical for Cast Bullet Performance

Have you ever wondered why your meticulously cast bullets might not perform as expected, or why you're experiencing excessive lead fouling in your firearm's barrel? The answer often lies in inconsistent bullet dimensions and inadequate lubrication. When a cast bullet is fired, it must perfectly fit the bore of your firearm to ensure a proper gas seal and stable flight down the barrel.

• Consistency is Key: Bullets that are even slightly undersized can lead to "gas cutting," where hot gasses bypass the bullet, eroding the base and causing deformation. This results in poor accuracy, keyholing, and increased lead fouling. Oversized bullets, on the other hand, can be difficult to chamber and may lead to dangerously high pressures if forced into the bore. A bullet sizing die brings your cast bullets to a precise, uniform diameter, ensuring optimal bore fit.
• The Role of Lubrication: Proper bullet lubrication serves multiple vital functions. First, it reduces friction as the bullet travels down the barrel, minimizing wear on both the bullet and the firearm. Second, it helps prevent lead deposits from accumulating in the rifling, a common issue known as "leading." Leading degrades accuracy, increases cleaning time, and can even become a safety concern. A good lubricant, applied effectively, creates a barrier that prevents direct metal-to-metal contact between the bullet and the barrel.
• Gas Checks for High Velocity: For many cast bullet applications, especially those approaching higher velocities typical of jacketed rounds, a "gas check" is essential. A gas check is a small copper cup attached to the base of the bullet. It protects the bullet's base from the scorching hot combustion gases, preventing deformation and leading. It also helps the bullet grip the rifling more effectively, improving stability and accuracy at higher speeds. The Lee Precision Classic Bullet Sizing Kit not only sizes and lubricates but also seamlessly seats and crimps these crucial gas checks.

Unpacking the Lee Precision Classic Bullet Sizing Kit: Design and Components

The Lee Precision 90055 New Lube & Size Kit (UPC: 734307900557) is engineered for simplicity, durability, and effectiveness. Its construction from robust steel ensures longevity and reliable performance, even with frequent use.

At its core, the kit comprises three essential components:

1. Sizer Die: This is the heart of the system. Crafted from hardened steel, the sizing die precisely reduces your cast bullets to the desired diameter (e.g., .452 for many .45 caliber firearms). It features an internal chamber that both sizes the bullet and simultaneously applies bullet lubricant through strategically placed lubrication grooves. The bullet is pushed through the die, rather than into it, ensuring smooth operation and consistent sizing.
2. Bullet Punch: This component works in conjunction with your reloading press. It pushes the cast bullet through the sizer die. The punch is designed to accommodate various bullet nose shapes without deforming them, ensuring the integrity of your projectile.
3. Lube Reservoir/Catcher: As the bullet is pushed through the sizer die, excess lubricant (which you supply, such as Lee Liquid Alox) and the sized bullet are collected. This integrated design keeps your workspace clean and makes the process efficient.

A standout feature of the Lee Precision Classic Bullet Sizing Kit is its universal compatibility. It is designed to fit any standard reloading press with a 7/8x14 thread, making it a versatile addition to virtually any reloader's bench. Whether you operate a single-stage press, a turret press, or even a progressive press (though sizing is often done offline for cast bullets), this kit will integrate seamlessly into your existing setup. The steel construction ensures it can withstand the forces involved in pushing lead bullets through a precision die, providing consistent results shot after shot.

How to Use the Lee Precision Classic Bullet Sizing Kit: A Step-by-Step Guide

Using the Lee Precision Classic Bullet Sizing Kit is remarkably straightforward, even for those new to bullet sizing. Here's a general overview of the process:

1. Prepare Your Cast Bullets: Ensure your cast bullets are free of any casting sprue or imperfections on the base that might interfere with seating. For optimal results, use clean, deburred bullets.
2. Apply Lubricant: The Lee sizing system is designed to work efficiently with various bullet lubricants. Lee Liquid Alox is a popular choice due to its ease of application and effectiveness. For some lubricants, you may tumble-lube your bullets before sizing, while others are applied during the sizing process. For kits that apply lube during sizing, you'll ensure your chosen lubricant is ready for application.
3. Install the Sizer Die: Screw the Lee Precision Sizer Die into the top station of your reloading press. Ensure it is securely tightened.
4. Insert the Bullet Punch: Place the bullet punch into the ram of your press.
5. Position the Bullet: Place a cast bullet, base-first, onto the shell holder (or directly into the ram if using a universal shell holder with a specific press setup).
6. Size the Bullet: Slowly raise the ram, pushing the bullet up into the sizer die. As the bullet passes through the die, it will be precisely sized to its final diameter, and if using a lubricant reservoir system, it will be lubricated as it passes. If seating a gas check, this is the stage where the gas check is firmly crimped onto the bullet's base.
7. Collect the Sized Bullet: As the ram reaches the top of its stroke, the sized and lubricated bullet will push through the die and drop into the integrated catch tray or designated container.
8. Repeat: Continue this process for all your cast bullets.

This streamlined process ensures consistent sizing and effective lubrication, readying your bullets for the final stages of reloading. The efficiency of the system means you can quickly process large batches of bullets, saving you valuable time at the reloading bench.
