Lee Precision 91558 Pro 4000 Press Kit 44 Special/Magnum

The Lee Precision Pro 4000 press kit is a true progressive reloading press designed for handloaders who want serious production capacity without the premium price tag of larger systems. Built around a modular platform that lets you control your own level of automation, the Pro 4000 handles 44 Special and 44 Magnum with the same no-fuss approach Lee is known for. Whether you're loading one round or ramping up to serious volume, this press adapts to your workflow—no complicated adjustments required as you switch between automation levels or change calibers in seconds.

What sets the Pro 4000 apart is the Breech Lock quick-change system across all four press stations. Once you set your dies into the colored spline drive bushings during initial setup, swapping calibers becomes instant work—no repositioning, no recalibration. The included 3-die carbide set, shell plate, Universal Case Feeder, and Auto-Drum Powder Measure give you a complete reloading station right out of the box. Add in the Safety Prime system with convenient through-ram primer disposal, and you've got a setup that handles the tedious parts while you focus on quality rounds.

Lee included the features that matter: a wood-grip ergonomic roller handle for hours of comfortable operation, large and small priming arms to match your primer sizes, and a hex wrench with built-in storage rack so you have the caliber-change tools at hand. The auto case placer works without adjustment, and the whole system is designed around the idea that reloading shouldn't mean fighting your equipment. This is a working press for serious handloaders tackling magnum pistol rounds who want reliability and speed in one modular platform.

How quickly can I change from 44 Special to 44 Magnum?

The Breech Lock quick-change system allows you to swap between calibers in seconds. After your initial die setup into the Breech Lock bushings, changing calibers requires no adjustments—just change out the shell plate and bushings. The press itself requires only the hex wrench for the swap.

Can I use this press if I want to automate only some of the reloading steps?

Yes. The Pro 4000 is built on a modular design that lets you control how much automation you use. You can run it as a full progressive press with case feeding and powder measure, or dial back the automation to manual steps—all with no press adjustments needed to change your workflow.

Is this a good progressive press for someone starting out?

The Pro 4000 is designed with beginners in mind. The inclusion of a complete die set, case feeder, powder measure, and priming system means you don't need to buy accessories separately. The no-adjustment Breech Lock system and straightforward design make it accessible for new reloaders, while the modular platform allows you to grow your technique over time.
