Hornady Lock-N-Load Auto Prime Upgrade Kit

The Hornady Lock-N-Load Auto Prime Upgrade (Hornady part no. 085570) adds automated primer feeding to a handloader’s press setup, part of Hornady’s well-known Lock-N-Load system built around quick-change bushings and fast tool swaps. This upgrade functions as a primer feeder with a multi-size thread pattern, letting a reloader prime cases without the repetitive hand-feeding that slows down a high-volume reloading session. Hornady designed the Lock-N-Load system to speed up bench work across the board, and this auto prime upgrade extends that convenience specifically to the priming step.
