Mapper, I try to make my first and heavies measure: "Will doing ________ improve consistency and can I do (what is needed) consistently from cartridge to cartridge?".

As an example, I went from reaming out crimps to swaging them because I noticed that it was pretty darned easy to ream the pockets inconsistently. Besides the Dillon Superswage 600 is about . . .600 times, faster.
