Hi all, I have both the large and small rifle primer K&M primer pocket correction tools and cannot figure out how to get the depth set. I know they say they come set to .131 & .122 respectively, but for me they bottom out at ~.1745 & ~.1345. I know you adjust using the set screw, but these measurements are set with the cutter seated as far as possible. Am I measuring wrong or misunderstanding the set depth? Anyone else have this issue? Thanks in advance.
