What do you think? Defective sensor? Thanx.

Possible bad sensor.....but you're way too close to the chrono with a rifle! 10-15 feet is fine for a handgun....but 30 feet is more like it with a rifle! Every chrono I've ever used gave flaky results when the unit was too close (as in less than 30'!) to the rifle!
