Lee Pro 4000 Press Kit Lee 91550 45acp Pro 4000 Press Kit

The Lee Pro 4000 Progressive Press is a full-featured reloading system that delivers progressive press capability at a price that won't break the bank. Built for shooters who want to load multiple rounds per stroke without the complexity or cost of premium equipment, the Pro 4000 comes complete with everything needed to start reloading 45 ACP right out of the box. Whether you're a new reloader looking to get into the hobby efficiently or an experienced hand wanting a dedicated 45 ACP setup, this kit combines modular design with genuine ease of use — no confusing adjustments required to switch between operational modes.

The kit's standout feature is its breech lock quick-change system, built into all four press positions. Once you dial in your dies into the included spline drive bushings for 45 ACP, swapping calibers takes seconds with zero readjustment. That modularity extends throughout: run it fully automated with the Universal Case Feeder and Auto-Drum Powder Measure, or dial back the automation and run manual operations as you prefer. The included Safety Prime system, auto case placer, and through-the-ram primer disposal tube keep your workflow smooth and your setup organized.

What comes in the box speaks to Lee's value proposition: three-die carbide set sized for 45 ACP, shell plate, case feeder, powder measure, both large and small priming arms, wood grip roller handle, colored breech lock bushings, and a hex wrench with storage rack. This isn't a bare press; it's a complete reloading station. The ergonomic roller handle and built-in tool organization transform what can be tedious hand work into something genuinely comfortable during longer loading sessions.
