I have a strain pressure measuring system. It's a Faber unit before Ristow offered his Pressure Trace (I also have an unused PT). The Faber captures Peak Pressures (actually it produces a number that he termed "microstrain" that I have to convert to psi via a closed vessel formula. I primarily used it to work up service rifle loads for the 90gr JLK (to keep from blowing ourselves up in uncharted territory).
Funny I just decided I needed to get a PTII and found they're discontinued. I have an email in with Schaefer with fingers crossed.
