Accu-Prime™ Auto-Load

Lyman’s Accu-Prime™ Auto Load tool, one of the fastest and most accurate priming tools available! 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 to primer seating depth. Our patented adjustable priming punch is unique in that it stops against the bottom surface of the cartridge case. In this manner, you can control the exact amount of primer depth below the bottom surface of the case. 

Additionally, the Accu-Prime Auto-Load uses an unique linear rail system for the primer feed tubes. This produces an extremely smooth primer feed operation, and consistent primer drop.  

The tool is operated by a side handle which activates our slick camming system for easy primer seating. 

Works with all brands of standard shellholders.
