Shooting Chrony Chronograph.
Used primarily when developing a new load. The chronograph itself is 25 years old and there's no provision for user calibration, so I don't use it so much to measure actual velocity as the velocities reported could 5 or 10% high or low. I use it principally to ensure consistency of the velocity within the string.
