Lee Precision Auto Breech Lock Pro progressive press (press only)

Lee Precision Auto Breech Lock Pro

The Auto Breech Lock Pro is Lee Precision’s four-station progressive press, also listed in the catalog today as the Pro 4000. It automatically indexes the shell plate with every cycle of the lever and integrates automatic priming, so that a finished cartridge is produced with every full stroke. It is the choice for those who produce significant volumes of pistol or rifle ammunition and want to exceed the speed of a single-stage press.

The four stations house the dies on quick-change Breech Lock bushings: the dies remain adjusted in their bushings, and caliber changes are reduced to replacing the bushings and shell plate. The priming system is automatic, with spent primers discharged through the ram, and Lee claims compatibility with all brands and sizes of primers for the current version. The production rate indicated by the manufacturer is in the order of 300-400 cartridges per hour, depending on the type of ammunition. The tube-style case feeder and the Deluxe Auto-Drum powder measure are available as accessories.

Recommended use

Suitable for progressive reloading of pistol and rifle cartridges with dimensions compatible with the four stations.
