The Hornady Lock-N-Load AP Progressive Press Shell Plate #57 is a caliber-specific component designed for shooters who reload on Hornady's Lock-N-Load AP progressive press. This shell plate indexes and positions your cartridge cases at each reloading station, making it a critical wear item that determines which calibers your press can handle. If you're switching between calibers or building a versatile reloading setup, having the correct shell plate for each cartridge is essential—and that's where the #57 comes in.
Built from quality materials engineered for durability, the #57 shell plate is designed to withstand years of reloading without premature wear or case-positioning errors. It's compatible with the modern Lock-N-Load AP press and also works with older Hornady Projector Press models, making it a practical addition if you're working with vintage equipment. The quick-change design of the Lock-N-Load system means swapping calibers doesn't require tools or frustration—just remove the current plate and lock in the next one.
Whether you're a high-volume handloader, a precision rifle cartridge specialist, or someone who likes to reload multiple calibers, having the right shell plate on hand keeps your press ready to go. The #57 is the specific component your press needs for its designated cartridge range, so verify compatibility with your current setup before ordering.
