Hornady Shell Plate #11 for Lock-N-Load AP and Pro-Jector
The Hornady Shell Plate #11 is the precision component that makes your Lock-N-Load AP or Pro-Jector press work smoothly through every reload. Whether you're running high-volume pistol sessions or rifle rounds, this shell plate positions your case correctly at each station—a small part that matters enormously when you're chasing consistent brass prep and bullet seating. Shell Plate #11 fits multiple calibers that share the same case head diameter, so it's worth checking Hornady's shell plate compatibility chart to see what you can run before buying additional plates.
Installation is straightforward on both Lock-N-Load AP (EZ-Ject and wire ejector versions) and Pro-Jector equipment. If your press uses the older spring-type cartridge case ejector system, you'll need to order the Hornady Auto press retrofit kit (749-012-552) to use modern shell plates—something worth confirming before you load. Once you're set up, this plate is built to handle the precise indexing these progressive presses demand.
Hornady shell plates are engineered to tight tolerances so cases seat and eject reliably, trip after trip. If you're not sure which shell plate number you need or have questions about retrofit compatibility, Sinclair's tech line is available to help.
