My shooting Chrony has been shot three times with a 9mm Luger (glancing blows, admittedly, but metal got bent and plastic got broken)), but it is still working and giving accurate readings. Also, wind has blown it over several times and the front faceplate is splatterd from shredded plating from copper plated 9mm Berry's bullets that I sometimes push past the recommended maximum velocity. Light screens have been blown away numerous times by muzzle blasts. I have a dozen nuts and bolts and fiberglass tape holding the light screens together.
