The Lee Precision Pro 4000 Press Kit is a true progressive reloading press that delivers production-level output without the premium price tag of high-end equipment. Built for handloaders who want to step up from single-stage presses and load rifle and pistol rounds efficiently, this 38 Special/357 Mag kit arrives with everything needed to begin reloading immediately—carbide dies, shell plate, Universal Case Feeder, Auto-Drum Powder Measure, and Safety Prime system included. The modular design lets you run as automated or as hands-on as your workflow requires, with no finicky adjustments needed to switch between operation modes.
Cartridge changeover happens in seconds thanks to the Breech Lock quick-change system, which works across all four press stations without readjustment. Primer size changes are equally fast—swap the appropriate priming arm and you're ready to go. The press features an exclusive auto case placer and through-the-ram primer disposal with a built-in tube for safe, tidy spent primer collection. An ergonomic wood-grip roller handle reduces fatigue during long reloading sessions, and the kit includes four colored spline drive breech lock bushings, both large and small priming arms, and a hex wrench with a built-in storage rack for your tools—details that would cost extra on other platforms.
Once you set your dies into the Breech Lock bushings for your load, the system locks them in place for instant, repeatable changeover. This is a press built for reloaders who want speed and consistency without sacrificing control or dealing with constant calibration. If you're loading 38 Special and 357 Mag in volume and tired of the limitations of single-stage presses, the Pro 4000 bridges the gap between hobby reloading and serious production.
