Nah, I don't have any data on that. Jim Ristow at mfr for the PT had some data on rifle time/bullet travel down the barrel.

Oehler's Model 43 Ballistic Lab used basically the same type of strain gages as does his professional Model 83/84. When I posted about this device in the past, some were very skeptical. That's o.k., they should be. They should learn how and why this type of device collects data before they invest and trust in it. I've been around instruments nearly identical to this in years past for industrial applications and I'm comfortable with them.
