don't forget about your neck sizing mandrel it is one of the most important steps, setting neck tension, for me this was the single most improvement to lowSD and ES. As I have mentioned before I do Not use the decapping pin and ball that comes on the sizing die.. I take them out and use a large decapping die so my case neck does not get continually stretch back and forth. and after you fire the new cases you will have to bump your shoulder on the sizing die approx.2 thousands for the cases there is a ton of hands on work in this game but it is worth every step.
