I am currently using the RCBS primer pocket reaming tool, it works okay, it does seem to be getting dull pretty quickly. I am looking for one that lasts longer and works a bit quicker, I do not want to swage. Has anyone tried the burst fire or L.E. Wilson cutters or have another suggestion. I have also used a regular counter sink but I don't like the fact that they don't have a stop. I am using them in a drill press.
