I recognize that strain gage from Stress and Strain Analysis. Very good info, thanks!
I've been thinking of doing some personal studies of velocity out of a successively shortening barrel to study powder burn rates and estimate pressure curves under various conditions. I'd do this by shortening the barrel down to nothing and estimating pressure based on acceleration.
