Lyman Accu-Prime Manual Bench Priming Tool Ambidextrous Silver 7770075. What makes this tool so accurate is our patented adjustable priming punch. Other priming tools use the top surface of the rim to hold the case during priming and then either use "feel" for primer depth or a tool stop of some sort. However even tools with a stop are susceptible to rim thickness variations which will then transfer these variations in primer seating depth. Our patented adjustable priming punch is unique in that the primer cup acts as a stop as it contacts the bottom surface of the cartridge case. In this manner you can precisely control the exact amount of primer depth below the bottom surface of the case.
