Overview

Built for reloading .50 Action Express cartridges on Hornady Lock-N-Load AP presses, this shellplate is intended for shooters who want a dedicated fit for that case head size. Its subtle shell holder mouth radius and retained spring design are described to support smooth case insertion and steady operation during use. It is also compatible with Pro-Jector presses and can accommodate additional calibers with the same case head dimensions. For reloaders setting up a press around this cartridge, it provides a purpose-specific component rather than a general-purpose solution.
