Lee Precision APP Automatic Processing Press 90933

Lee Precision APP Automatic Processing Press 90933

The APP (Automatic Processing Press) is a compact single-stage press designed for repetitive case and bullet processing: decapping, primer pocket swaging, bullet sizing, and single-stage reloading operations. Automatic case feeding, with self-opening jaws, allows for processing large quantities of brass with a continuous motion without needing to insert pieces by hand one by one.

The frame is open-sided: stress passes directly from the steel linkages to the die, leaving visibility and room for the hands. The stroke exceeds 3 inches, allowing it to handle even belted magnum cases; the die carriers are made of aluminum and the lever is counterbalanced so it does not fall on its own. The die can be mounted in either the top or bottom of the press, a feature that distinguishes the APP from traditional single-stage presses and makes it suitable for both bullet sizing and swaging.
