Hornady Lock-N-Load AP Progressive Press Shellplate - Precision Reloading Tool for Efficient Ammo Production

A Hornady Lock-N-Load AP progressive press shellplate is the foundation of fast, consistent ammunition production on your Hornady reloading press. This precision-machined component holds cartridge cases in the correct position through each stage of the reloading cycle—sizing, priming, powder charging, bullet seating, and crimping. Whether you're loading rifle or pistol ammo, the right shellplate for your caliber is essential to reliable operation and repeatable results.

Hornady offers shellplates to fit most common calibers, and because many cartridges share the same case head dimensions, a single shellplate often works for multiple loads. Shellplates are engineered to fit Lock-N-Load AP presses (both EZ-Ject and wire ejector models) and Pro-Jector presses. If your press still uses the older spring-type cartridge case ejector system, you'll need the Hornady Auto press retrofit kit (749-012-552) to ensure proper compatibility.

Choosing the correct shellplate for your caliber is straightforward—consult the Hornady Shellplate Chart to match your cartridge to the right plate. Precision fit and durable construction mean your press will handle high-volume reloading sessions without drift or wear. For questions about compatibility with your specific press or caliber, Sinclair tech support is available at 800-717-8211.

Frequently Asked Questions

What calibers does this shellplate fit?

Shellplates are caliber-specific. Hornady offers plates for most common rifle and pistol cartridges. Check the Hornady Shellplate Chart to confirm your caliber matches the plate you're considering. Many plates will also load additional calibers that share the same case head dimensions.

Is this compatible with my Lock-N-Load AP press?

Shellplates are designed to fit Lock-N-Load AP presses with both EZ-Ject and wire ejector systems. If your press has the older spring-type cartridge case ejector system, you'll need to install the Hornady Auto press retrofit kit (749-012-552) before this shellplate will work properly.

What if I have the old-style spring ejector?

Hornady sells the Auto press retrofit kit (749-012-552), which adapts older spring-type ejector systems to work with modern shellplates. Contact Sinclair tech support at 800-717-8211 if you're unsure whether your press needs the retrofit.

Does this shellplate work with Pro-Jector presses?

Yes, Hornady Lock-N-Load AP shellplates are also compatible with Pro-Jector presses.
