For many shooting enthusiasts, the journey of crafting your own ammunition is about more than just cost savings; it’s a connection to the craft, a deeper understanding of ballistics, and the pride of sending rounds downrange that you’ve meticulously created. One of the most popular cartridges among reloaders is the versatile and ubiquitous nine-millimeter Luger, and at the heart of any successful reloading endeavor lies access to reliable load data. This article delves into the world of Lee 9mm Load Data, providing a comprehensive guide for both novice and experienced reloaders. We’ll explore the essential components, provide load recommendations, emphasize safety precautions, and guide you through the reloading process. Prepare to embark on a journey into the art and science of creating your own accurate and reliable 9mm ammunition.
The nine-millimeter Luger, also known as the 9x19mm Parabellum, holds a significant position in the history of firearms. Born in the early 20th century, it was originally designed for the Luger pistol, quickly gaining acceptance within military and law enforcement circles due to its manageable recoil and relatively high capacity. Its adoption by numerous militaries worldwide and its use in various submachine guns solidified its place in history.
The continued popularity of the nine-millimeter today can be attributed to several factors. Its popularity stems from its versatility, its widespread availability of firearms chambered in this caliber, its relatively moderate recoil, and its cost-effectiveness compared to some other centerfire rounds. It strikes a balance between power, controllability, and magazine capacity that makes it a favored choice for concealed carry, personal defense, target shooting, and competitive sports. This enduring popularity makes reloading for the 9mm a practical and rewarding endeavor.
At the core of any cartridge, including the nine-millimeter, are several fundamental components that work in concert to propel the bullet down the barrel. These key components are crucial to understand to safely and effectively reload. Understanding the function of each component is key to a safe and effective reloading session.
The brass casing is the sturdy container that houses all other components. The primer ignites the propellant, the powder provides the energy for propulsion, and the bullet is the projectile that is sent downrange. These parts interact with each other to produce the explosion needed to make a firearm function.

Essential Components for Reloading 9mm
Brass Cases
These are the reusable containers that hold the primer, powder, and bullet. Case inspection is crucial; you must thoroughly examine each case for damage such as cracks, bulges, or signs of stress. Cases should also be cleaned. This removes soot and grime that can build up over time. Lee offers several tools for case preparation, including case trimmers, case tumblers, and case prep tools, all designed to help you maintain the brass at its highest quality. Many reloaders find that brass preparation is very therapeutic, and an investment in the right tools will make this enjoyable.
Primers
Primers provide the initial spark that ignites the gunpowder. There are several sizes and types of primers. For nine-millimeter reloading, you will typically need small pistol primers. Selecting the right primer is crucial, and Lee offers primer tools that assist in the placement of the primers with precision. The choice of primer can influence the overall performance of a round. Understanding how the primer and powder interact is critical to achieving a balanced load.
Bullets
The projectile fired downrange, bullets come in various weights and designs, each suited for different purposes. Common bullet weights for the nine-millimeter range from 115 grains to 147 grains, with other weights available. Bullets are available in various types, including full metal jacket (FMJ) for target practice, jacketed hollow point (JHP) for self-defense, and round nose (RN). Consider the intended use of your ammunition when choosing a bullet. Heavier bullets often provide more kinetic energy. Bullet selection is crucial for the performance you want to achieve.
Powder
This is the propellant, and the selection of the correct powder is a critical factor. Various powders are designed for the nine-millimeter. Different powders burn at different rates, impacting the velocity and pressure generated. Popular powders for 9mm reloading are readily available and easy to find. Selecting the right powder for your bullet weight and desired performance characteristics is a critical step. Always refer to reputable load data sources such as the *Lee Reloading Manual* and manufacturer websites for load recommendations.
Lee 9mm Load Data and Recommendations
Lee Precision reloading equipment is respected by reloaders of all levels. Their reloading manuals provide a wealth of load data. Understanding how to interpret this load data, and to follow its recommendations, is important for your safety.
Accessing reliable load data is the cornerstone of safe and effective reloading. Load data provides the specifications for assembling a safe and effective cartridge.
Lee offers comprehensive load data within their reloading manuals, typically available in print and often accessible online. These resources provide detailed information on the appropriate powder charges, bullet weights, primer types, and overall cartridge lengths (OAL) for various nine-millimeter loads. Remember, always consult the most current edition of the *Lee Reloading Manual* or visit Lee Precision’s official website for the most up-to-date and verified load data.

This table structure organizes information, allowing for easy comparison of different load combinations. This will make it easier for you to learn and experiment with.
Load Considerations
When you begin loading you will want to consider several factors. Bullet seating depth will greatly affect pressure, impacting velocity. Overall cartridge length (OAL) is another important measurement. Choosing the right load depends on what you intend to use the loads for. Are you looking for a target practice load? Or, do you want to produce a load with more velocity? These are all considerations.
Reloading Process with Lee Equipment
Once you have gathered all of the necessary components and have the load data in hand, you can start your reloading process. Here’s what to expect when you work with your Lee 9mm Load Data.
Equipment Needed
The following equipment is needed:
Lee Reloading Press: Whether you choose a single-stage press or a progressive press, the reloading press is the heart of the operation. It houses the dies and provides the mechanical leverage needed to size the cases, seat the bullets, and perform other steps.
Lee Dies: These essential tools perform various functions, including sizing the case, expanding the case mouth to accept the bullet, seating the bullet to the correct depth, and crimping the case mouth to secure the bullet. Lee offers high-quality die sets for the nine-millimeter.
Lee Powder Measure: This tool accurately dispenses the measured amount of powder into each case. Consistent powder charges are essential for achieving consistent performance.
Other Essential Tools: A case trimmer helps maintain correct case length, and a priming tool seats the primers into the case.
Step-by-Step Reloading Process
Here’s how the process works:
Brass Preparation: Start by cleaning the brass, either with a tumbler or by hand. Inspect each case for cracks, dents, or other damage. If cases are dirty or tarnished, then clean them by tumbling them. Trim the cases to the correct length using a case trimmer.
Priming: This involves seating a new primer into the primer pocket of each case. The Lee priming tools provide a convenient and safe method for accomplishing this. This process often involves an attachment to the reloading press.
Powder Charging: Use the powder measure to dispense the correct powder charge into each case. Make sure to carefully follow the load data and consult your scale to ensure you have the right amount.
Bullet Seating and Crimping: Seat the bullet to the correct overall cartridge length (OAL) using the seating die. Then, crimp the case mouth with the crimping die.
