The Lee 90700 Auto Bench Prime is a dedicated bench-mounted priming tool built for reloaders who want speed and ergonomics without the complexity of adapting a full press. If you're processing large volumes of brass or simply tired of the repetitive hand-priming routine, this straightforward single-purpose tool delivers. The symmetrical lever design provides just enough mechanical advantage to seat primers—even stubborn ones—with finger pressure alone, no excessive force required.
The Auto Bench Prime's dual priming assemblies handle both large and small primers, constructed from clear polyester so you can visually confirm primers feeding from the tray into the pocket. Switching between primer sizes takes seconds, and the included folding tray cuts your setup time drastically—fill and prime directly from standard primer boxes thanks to the built-in flipper feature. Because this tool uses its own inexpensive shellholders rather than press-specific ones, you're not locked into constant swaps between reloading operations.
Mounting is flexible: bolt it to a Lee Bench Plate system or secure it directly to your existing workbench. For handloaders focused on the priming stage itself—whether you're prepping match brass, processing bulk hunting rounds, or simply want a dedicated station for this critical step—the Auto Bench Prime consolidates the task into a repeatable, low-fatigue workflow.
