The Hornady Lock-N-Load AP Progressive Press Shell Plate #12 is the caliber-specific component that makes your progressive reloader adaptable to different cartridges. This shell plate is engineered to work with Hornady's Lock-N-Load AP press (both EZ-Ject and wire ejector versions) and the Pro-Jector, letting you swap calibers without swapping your entire press. Each plate is sized to handle its primary caliber, but many also accommodate additional cartridges that share the same case head dimensions — a practical feature when you're loading multiple rounds across your ammunition pile.
If your press runs the older spring-type case ejector system, you'll need to pick up the Hornady Auto press retrofit kit (749-012-552) before installing this shell plate. For reloaders with modern equipment already set up with the newer ejector design, the #12 plate drops right in and gets you loading. Hornady's Lock-N-Load system is built around quick-change components, so swapping plates between sessions takes seconds rather than minutes.
Whether you're running high-volume pistol loads or precision rifle work, having the right shell plate for each caliber you shoot keeps your press setup tight and your operation smooth. Check Hornady's shell plate compatibility chart to confirm the #12 matches your cartridge, and verify your ejector type before ordering the retrofit kit if needed.

The #12 shell plate is designed for Hornady Lock-N-Load AP presses with both EZ-Ject and wire ejector models, as well as the Pro-Jector press. If your press has the older spring-type case ejector system, you'll need to purchase the Hornady Auto press retrofit kit (749-012-552) before installing this plate.
If your press was manufactured with the newer wire or EZ-Ject ejector, the shell plate installs directly. Presses with the old-style spring ejector require the retrofit kit mentioned above.
Yes — many Hornady shell plates accommodate multiple cartridges that share the same case head dimensions, making a single plate useful for similar rounds you may reload.
