The Hornady Lock-N-Load AP Progressive Press Shell Plate #56 is a caliber-specific component designed for reloaders who want quick, precise case indexing on their Hornady Lock-N-Load AP or Pro-Jector progressive press. If you're running high-volume production or switching between similar cartridges, having the right shell plate on hand eliminates setup delays and keeps your workflow moving. Shell plate #56 accommodates multiple calibers that share the same case head dimensions, making it a practical addition to any reloading bench that handles more than one load.

Hornady's modular approach to their progressive presses means you can keep several shell plates in inventory and swap them in seconds—no need to break down your press every time you change calibers. That efficiency is especially valuable if you're preparing ammo for different hunting seasons, range sessions, or match prep. The shell plate seats your case consistently on each station, which translates directly to uniform case positioning during resizing, powder charging, and bullet seating.

Compatibility depends on your press configuration. If your Lock-N-Load AP or Pro-Jector still uses the older spring-type cartridge case ejector system, you'll need the Hornady Auto press retrofit kit (part number 749-012-552) to use current shell plates. Both the EZ-Ject and wire ejector models of the Lock-N-Load AP work with modern shell plates out of the box. Refer to Hornady's shell plate compatibility chart to confirm which calibers or case families your #56 plate handles, and verify your press version before ordering.
