Overview

Built for reloaders who want a straightforward single-stage press setup, this model centers on an O-frame design with a larger-than-average 4" opening for added hand clearance. It includes the Lee Lever Prime System and a Breech Lock Quick Change die system, so die changes can be made without re-adjusting the die each time. The spent primer catcher is designed to direct primers to the trash can, helping keep the bench cleaner during routine loading sessions. With all-steel linkage, an adjustable-length lever, and one Breech Lock quick-change bushing included, it offers a practical feature set for hunters and shooters who value efficient, repeatable reloading work.

Pros

  • O-frame design with a large 4-inch opening for added hand clearance
  • Includes Breech Lock Quick Change die system for fast die changes
  • Lee Lever Prime System is built into the press for priming
  • Positive spent primer catcher routes primers directly to the trash can
  • All-steel linkage with adjustable-length lever adds useful control
  • Includes one Breech Lock quick-change bushing

Considerations & Trade-offs

  • The press uses a cast aluminum frame, so it is not an all-steel press despite the steel linkage.
  • It includes one Breech Lock quick change bushing; additional bushings would need to be added separately if you want multiple dies set up for quick swaps.
  • The 4" opening provides generous hand clearance, but the overall O-frame design is still a single-stage setup rather than a progressive press.
  • The adjustable-length lever and Lever Prime system add convenience, but they also introduce more moving parts than a very basic press design.
