The Lyman's Accu-Prime tool stands out for its exceptional accuracy and precision in priming tasks, thanks to its patented adjustable priming punch. Unlike other priming tools that rely on the rim's top surface to hold the case and use either feel or a tool stop for primer depth, the Accu-Prime addresses rim thickness variations that can affect primer seating depth. Its innovative design allows the primer cup to act as a stop by contacting the bottom surface of the cartridge case, enabling precise control over the primer depth below the case's bottom surface. Additionally, the tool features a smooth helix camming system for raising and lowering the priming punch, operated by a unique side lever. Primers are manually placed into the priming cup and seated using the 90-degree travel side lever. The Accu-Prime is versatile, accommodating both right- and left-hand operation.
