Hornady 085570 Lock-N-Load Iron Press Auto Primer Upgrade

The Hornady Lock-N-Load Iron Press Auto Primer Upgrade is the optional automatic priming accessory designed to convert a manual Lock-N-Load Iron Press into a smooth, gravity-fed priming station. Built by Hornady for serious reloaders, this upgrade takes the most repetitive step in the reloading process and handles it for you, automatically feeding primers into the press so you never have to seat them by hand one at a time.

The primer feeder is constructed from a rugged combination of cast iron and hard plastic, giving it the weight and durability to stay planted during long reloading sessions. It uses a 1-hole priming station and a multi-size thread pattern that accepts both small and large primers, so you can move between rifle and pistol calibers without swapping hardware. Whether you are loading bulk 9mm for the range or fine-tuning precision rifle rounds, the upgrade keeps primer seating consistent from the first case to the last.

Installation is straightforward for owners of the Lock-N-Load Iron Press: the feeder mounts directly to the press frame and integrates with the standard priming stroke. The result is faster cycle times, fewer dropped or mis-seated primers, and a noticeably easier workflow compared to hand-priming on the press. MPN: 085570.
