I just watched Scott.....
...at Kentucky Ballistics blow away a chrono with a .500 Bushwacker. Looks like we ain't alone.

I was given a ProChrono by my wife's uncle that was surplus to him. It had old cardboard skyscreens with it so I got on the company website and ordered some new plastic/nylon screens. They nicely sent a new set of ss rods with the screens that were much nicer than the old ones. I promptly shot one in half with a .223. So my score stands at one rod. They're pretty skinny and a lot harder to hit than the chronograph itself.
P.S. my buddy found that a sabot from a muzzle loader won't fully penetrate a chronograph but will destroy the screen/readout.
P.P.S. I bought myself a LabRadar for Christmas, it should be pretty hard to shoot it.
