[QUOTE="nicholasjohn, post: 1931755, member: 109113"] I have a blade mic, and this is why I got it. Works great. I use Hodgdon's specs, which state that max pressure coincides with .0005 - .0006" case head expansion. Thi is when measurements are taken on the case web, just ahead of the extractor groove. At that point, factory loads typically expand around .0003". There is another method, which was employed by Ken Waters - he measures what he calls the "pressure ring" which is where the case walls meet the web. His numbers for max pressure look more like yours do. Which point on the case are you measuring ? [/QUOTE]
