Anybody ever play around with strain-gauge chamber pressure measurement? (Read 1242 times)

I've been trying to make shotgun loads, frequently ending up with modified book loads.

Considering I can't ship shells to the mainland for pressure testing, the idea of installing a strain gauge on a Benelli Nova and measuring my own pressures has some appeal.


Does anybody in Hawaii have such a setup already, or experience with such a setup?
