Its primary function is straightforward: to seat the primer squarely and consistently into the primer pocket of the brass case, readying the case for the next stages of the reloading process. The design itself prioritizes efficiency and user-friendliness, aiming to streamline the priming step.
Design and Operation
The tool is built with a bench-mounted design, which typically involves bolting or clamping the unit to a reloading bench. This provides a stable platform, allowing for controlled and accurate primer seating. The core operation revolves around a lever action. By pulling the handle, the reloader can smoothly feed a primer from the primer feed mechanism, align it with the primer pocket, and then seat it with consistent pressure. This consistent seating is vital for ensuring reliable ignition and optimal performance of the loaded round. The feel of the handle provides tactile feedback, allowing the reloader to get a good sense of the primer seating depth. This feedback is an advantage that’s often preferred over tools that lack this sensitivity.
Key Components
The Auto Prime Bench consists of several key components that work in harmony. The main priming tool itself provides the mechanical advantage and structure for the entire process. The primer feed mechanism delivers primers from a tray to the priming station. This usually involves a simple yet effective system to automatically feed primers from a tray into the priming tool itself. The shell holder is, of course, also necessary. The shell holder is specifically designed to hold the brass case securely, allowing for proper alignment with the primer. The tray is designed to hold a supply of primers, making the operation smoother and more efficient.
