This comprehensive guide will delve into the world of bullet sizing, explain why it's crucial for your reloaded ammunition, and provide an in-depth look at how the Lee Lube & Size Kit empowers reloaders to produce highly consistent and accurate rounds.

Why Bullet Sizing is a Cornerstone of Accurate Reloading

Many reloaders, especially those new to casting their own projectiles or those working with bulk-purchased cast bullets, often ask: "Do I really need to size my bullets?" The answer is a resounding yes. Bullet sizing, also known as swaging, is the process of uniformly reducing the diameter of a bullet to a specific, precise measurement. This is particularly vital for cast lead bullets but can also be beneficial for some jacketed projectiles.

Here’s why precise bullet sizing is a non-negotiable step for anyone seeking to create high-performance ammunition:

• Ensuring Consistent Bore Fit: Firearms are manufactured to specific bore diameters. For a bullet to perform optimally, it must be slightly larger than the barrel's groove diameter. This ensures a proper seal, preventing gas blow-by and allowing the rifling to impart the necessary spin for stability. Undersized bullets can "rattle" down the bore, leading to poor accuracy, excessive leading (with lead bullets), and reduced muzzle velocity. Oversized bullets, while potentially providing a good seal, can be difficult to chamber and may generate dangerously high pressures. Sizing guarantees a consistent, optimal fit.
• Preventing Leading in Barrels: A common issue with cast lead bullets is lead fouling or "leading" in the barrel. This occurs when molten lead smears onto the rifling, reducing accuracy and requiring strenuous cleaning. A major cause of leading is an undersized bullet that allows hot gases to bypass the bullet base and melt the lead. Proper sizing, coupled with effective lubrication, creates a tight seal, significantly reducing or eliminating leading, thereby extending barrel life and simplifying cleaning.
• Improving Accuracy and Consistency: Uniform bullet diameter is directly correlated with consistent barrel lock-up and exit. When every bullet leaving your handloaded ammunition is of the exact same size, it will interact with the barrel's rifling in the same way, shot after shot. This consistency translates directly into tighter groups and improved accuracy, making it easier to hit your target reliably.
• Facilitating Smooth Feeding and Chambering: Correctly sized bullets ensure that loaded cartridges feed smoothly from magazines and chamber effortlessly into your firearm's breach. Overly large bullets can cause feeding malfunctions or prevent the action from closing completely, while undersized bullets might not headspace correctly, leading to unreliable ignition.
• Optimizing Lubrication: Bullet sizing dies often incorporate a mechanism for simultaneously lubricating the bullet. This lubrication is essential for reducing friction as the bullet travels down the bore, minimizing leading, and contributing to smoother operation.

The Ingenuity of the Lee Precision 90060 Lube & Size Kit

The Lee Lube & Size Kit, product number 90060, is engineered with the reloader's needs in mind, offering a simple yet highly effective method for preparing bullets. Designed for efficiency and precision, this kit transforms raw cast bullets or commercially available projectiles into perfectly sized and lubricated components ready for the reloading press.

What's included in a typical Lee Lube & Size Kit?

• Steel Sizing Die: The core of the kit is a hardened steel sizing die, precisely machined to deliver consistent bullet diameters. Unlike some competitor systems that require separate lubrication, Lee's unique design often incorporates a push-through style that applies lubricant as the bullet passes through. The steel construction ensures durability and a long service life, even with extensive use.
• Lee Resizing Lubricant: A tube of high-quality Lee Resizing Lubricant is typically included. This specialized lubricant is formulated to reduce friction during the sizing process and when the bullet travels down the bore, preventing leading and improving overall performance.
• Catch Container: A convenient plastic container is provided to collect the sized and lubricated bullets as they exit the die, keeping your workspace clean and organized.
• Push-Through Punch (Specific to Caliber): A specific push-through punch for the chosen caliber is part of the kit, designed to guide the bullet accurately through the sizing die.

The ingenuity of this system lies in its simplicity and effectiveness. Instead of complex hydraulic systems or multi-stage processes, the Lee Lube & Size Kit utilizes a direct, push-through method that achieves precise results with minimal effort. This design also often allows for concurrent lubrication, saving an extra step in the reloading process.

Step-by-Step Guide: How to Use Your Lee Lube & Size Kit

Using the Lee Lube & Size Kit is straightforward, even for those new to bullet casting or sizing. Here’s a general overview of the process:

• Mount the Sizing Die: Securely thread the Lee Sizing Die into the top station of your reloading press. Most standard single-stage or turret presses will accommodate the die. Ensure it is tightened firmly.
• Prepare the Lubricant: If using a Lee-style lubricant (like Liquid Alox), it can often be applied to bullets before or during the sizing process, depending on the specific method of the die. With some Lee dies, the sizing die itself contains grooves that hold the lubricant, which is then applied as the bullet is pushed through.
• Place the Bullet: Position a cast or jacketed bullet, base first, onto the shell holder (which should be appropriate for the caliber of the bullet's base, not necessarily the cartridge it will be loaded into).
• Insert the Push-Through Punch: Place the appropriate push-through punch onto the nose of the bullet.
• Size the Bullet: Slowly and steadily raise the press ram. The bullet will enter the sizing die, and the punch will push it through. As the bullet passes through the die, its diameter is uniformly reduced to the desired specification, and the lubricant is applied (if using a die that lubricates simultaneously).
• Collect Sized Bullets: As the bullet exits the bottom of the die, it will drop into the designated catch container.
• Repeat: Continue this process for all the bullets you intend to size and lubricate.

This process ensures that every bullet is uniformly sized and properly lubricated, ready for the next stages of your reloading process, such as seating and crimping into primed and powdered cases. The efficiency of the Lee system means you can quickly process large batches of bullets, saving valuable time and effort.

Frequently Asked Questions by Reloaders and Shooters

Understanding the nuances of bullet sizing and lubrication is key to successful handloading. Here are some common questions answered:

• "What's the best way to lubricate cast bullets?" While there are various methods, the Lee Lube & Size Kit offers an integrated solution. For Lee's push-through dies, a liquid lubricant like Lee Liquid Alox or a similar formulation is often applied by tumbling bullets in the lube before or after sizing, or by direct application within the die. This creates a uniform protective layer that reduces friction and prevents leading.
• "How do I choose the correct bullet diameter for my firearm?" The ideal bullet diameter is typically 0.001-0.002 inches larger than your firearm's groove diameter. Measuring your barrel's groove diameter using a slugging kit is the most precise method. For example, if your 9mm barrel has a groove diameter of .355 inches, you might size your bullets to .356 or .357 inches.
• "Can I size jacketed bullets with this kit?" While primarily designed for cast lead bullets, the Lee Lube & Size Kit can be used for some jacketed bullets if a slight diameter reduction is needed. However, most commercial jacketed bullets are manufactured to very tight tolerances and rarely require sizing. Always consult reputable reloading manuals for specific recommendations.
• "What are the benefits of using a steel sizing die?" Steel sizing dies, like those included in the Lee 90060 kit, offer superior durability and resistance to wear compared to dies made from softer materials. This ensures a consistent sizing dimension over thousands of uses, maintaining the precision of your ammunition for years to come.
• "How does proper sizing impact firearm accuracy?" Proper sizing ensures a consistent fit of the bullet within the bore, allowing the rifling to effectively engage and stabilize the bullet. This consistent engagement minimizes bullet yaw or wobble as it exits the muzzle, leading to a more predictable and stable flight path, directly translating to improved accuracy and tighter shot groups.
• "Is bullet sizing necessary for all calibers?" While crucial for cast bullets across all calibers to prevent leading and ensure consistency, the necessity for jacketed bullets varies. For most factory jacketed bullets, sizing is not needed. However, for extreme precision or certain specialized applications, some reloaders might choose to uniform jacketed bullets as well.
• "What are common mistakes to avoid when sizing bullets?" Over-lubrication can cause sticky bullets and messy handling. Insufficient lubrication leads to increased friction and potential leading. Using the wrong size punch or forcing an oversized bullet can damage the die or the bullet. Always ensure your equipment is clean and follow the manufacturer's instructions.
