[QUOTE="MNbogboy, post: 1745254, member: 18849"] I'm with the others on here with concerns it may be just chrono difference due to everchanging ambient light conditions. Readings from shot to shot in steady light conditions can be very consistent and also accurate. However partly cloudy, passing clouds, full sun, low sun, falling snow or even flies & mosquitos can affect readings. Having shot literally thousands of rounds over different chronograghs has been a good teacher. I use a magneto speed now and light condition variables have been eliminated. (A whole new set of problems with the barrel mounted device to be discussed at a different time). My guess is that lighting changed between your two groups. The "error" you had with one shot was my big clue. Overcast days are the most consistent for your machine. If you have access to a mag speed or better yet labradar you can verify your findings.
