[QUOTE="cowboy, post: 794452, member: 8833"] Been there - done that. My chrony read high compared to back to back with other chronographs as well as actual field testing. Dang near put a bullet through it one day. After settling down after a few days I called chrony. Sent it in and they re-calibrated it. By the way - they test/check/calibrate with a pellet rifle. Mine read consistently 35 fps high at 2850 fps. It is caused by the two reading eyes (little black boxes) being too close together or too far apart. [/QUOTE]
