Progressive reloading presses, like those manufactured by Lee Precision, represent a significant step up in efficiency for serious reloaders. This guide dives deep into the world of Lee progressive presses, exploring their features, benefits, and how they compare to other reloading methods. We'll cover everything from setup and operation to troubleshooting common issues, making you a confident user of your Lee progressive press.
Understanding Lee Progressive Presses
Lee Precision offers several models of progressive presses, each designed to meet different needs and budgets. Their popularity stems from a combination of affordability, robust design, and ease of use (once mastered). Unlike single-stage presses that perform one operation at a time, progressive presses automate multiple steps in the reloading process, dramatically increasing your output. This typically involves:
- Sizing: Resizing the spent casing to its original dimensions.
- Priming: Seating a new primer into the resized casing.
- Powder Charging: Metering and dispensing a precise amount of gunpowder.
- Bullet Seating: Seating the bullet to the correct depth.
- Crimping: Crimping the case mouth to securely hold the bullet in place.
These steps are all performed in a single press cycle, significantly speeding up the reloading process. Different Lee models may vary in the level of automation and features offered.

Setting Up Your Lee Progressive Press
Setting up a Lee progressive press correctly is crucial for safe and efficient operation. This involves several steps:
- Choosing the Right Dies: Select dies that are compatible with your chosen cartridge and press. Lee offers a wide variety of dies for various calibers.
- Mounting the Dies: Follow the manufacturer's instructions carefully when mounting the dies in the press. Proper die alignment is essential for accurate reloading.
- Adjusting the Dies: Each die needs to be precisely adjusted to perform its function correctly. Incorrect adjustments can lead to misfires, damaged cases, or inaccurate loads. Start with the manufacturer’s recommended settings and fine-tune as needed.
- Primer Feeding: Ensure the primer feed system is properly adjusted and that primers are consistently fed into the press.
- Powder Measurement: Calibrate the powder measure to dispense the correct amount of powder for your chosen load. This is critical for safety and accuracy.
Operating Your Lee Progressive Press
Operating a Lee progressive press efficiently takes practice. Begin with slow, deliberate movements, ensuring each step is performed correctly. Gradually increase your speed as you become more comfortable with the press. Always wear safety glasses and appropriate hearing protection when operating any reloading equipment.
Common Issues and Troubleshooting
Several common issues can arise when using a Lee progressive press:
- Double Charging: This is a serious safety hazard and can result from improperly adjusted powder measures or inconsistent primer feeding.
- Case Jams: This can occur due to improperly sized cases or improperly adjusted dies.
- Primer Failure: This can be caused by damaged primers or improperly adjusted primer feed systems.
Addressing these issues requires meticulous attention to detail and a thorough understanding of your press’s operation. Consulting the Lee manual, online forums, or experienced reloaders can help resolve most problems.
