Wilson and C&H, no pilots needed and just use a 223 shell holder. In fsct I keep one set up for 223 based cartridges, 20 Practical, 223, and 6x45mm and another set up for 22-205, 6mm-204 and 25-204 with a 204 shell holder. It is a pretty simple system for me, once set up there is no adjustments needed for all six cartridges.
