Poking the bear aside, Shooting Chrony doesn't have a great reputation for consistency. Were lighting conditions different between shots?
Thanks for the info. I don't know much about different chronographs, this unit is one my buddy bought and left at my house.
Lighting conditions were generally the same, full early afternoon sun. I had the poles and sunscreens setup. I set the chronograph about 11 feet away and have the angle set so that my horizontal reticle crosses all four brass connectors on the sunscreen poles and the vertice is through the center and on the target.
Maybe the unit is junk.
