My father loves the old Herters stuff and wanted a more precise way to control bullet seat depth. He ordered a Redding micrometer seating stem for a 204 ruger to seat his 22-250 bullets. We had to take a little off the top of the die body then slowly sanded it until the scale was right in the front of the window opening. We also had to cut some material off the bottom on the bushing that screws into the top of the die body. Last we had to chuck the seating stem up in the lathe and turned it down so it just fit inside the sliding sleeve of the Herters die. It looks like there are 2 different length Hertes die bodies and we ended up using the shorter version, longer version just has more threads. The project turned out great and hes happy with the results. I love the Redding dies with the micrometer tops. If you more it one mark that thing seats it perfect .001
