Hornady Lock-N-Load AP Progressive Press Shell Plate - #3

The Hornady Lock-N-Load AP Progressive Press Shell Plate #3 is a precision-engineered component designed for reloaders who demand quick caliber changes without sacrificing repeatability. This shell plate is engineered to work with Hornady's Lock-N-Load AP progressive reloading press system, enabling operators to transition between cartridge types efficiently while maintaining the consistent case positioning critical to quality ammunition production.

The #3 shell plate configuration accommodates specific cartridge families, allowing reloaders to swap calibers without replacing the entire turret assembly. Hornady's indexed design ensures precise case alignment at each station of the progressive press cycle—critical for proper primer seating depth, powder charge consistency, and bullet seating accuracy. The plate's durable construction is built to tolerate the mechanical stress of high-volume reloading sessions. Compatibility extends to both current Lock-N-Load AP models and older Hornady Projector Press variants, providing long-term value for shops upgrading or expanding their press lineup.

This component serves serious handloaders, competition shooters, and law enforcement armories that require consistent, cost-effective ammunition production. Whether loading match-grade rifle rounds for precision shooting or high-volume pistol ammunition for department training, the shell plate's indexed positioning reduces setup time and minimizes the human variables that degrade accuracy. Reloaders managing multiple calibers benefit from the quick-change design, which eliminates the downtime and complexity of full turret changes.

Shell plate compatibility is critical—the wrong plate configuration will cause case misalignment and production errors. Verify your cartridge family against Hornady's plate numbering system before ordering. The Lock-N-Load AP progressive press has earned widespread adoption in reloading communities for its modular design, and shell plate availability directly determines the range of calibers a single press can support efficiently.
