nunhunh, ain't shot mine.
I got a plan to not do that.
It took too long to save up, and I paid waay too much for the C.E.D. millennium-2, and I'm very careful about shooting over it.
Chrongraph? NO. Polygraph? YES! They obliged ammo makers to stop lying their derrieres off about the performance of their products in the Real World. Mine have gotten quite a bit of use in years past, when I was doing development stuff.
the advantage of one like Ben has is you can't really shoot the chronograph itself.
you can shoot the screens and arms and even the eyes but if you shoot the actual chrono... hoo boy, you got more to worry about.
I have had three of the first model Chrony's, the ones that only read one shot, red colored, and have black cardboard "wings". You can buy them for about $20 now because you have to do calculations with pen and paper.
Got my first one with an unburned powder kernel . Gave it away with that tiny perfect hole through the face lens and lcd of a Chrony Alfa . It was only $90 to get a Beta and $32 shipping ....... I caught a sale and replaced the Alfa for $109 ...... About 2 weeks later I scored a brand new Gamma less printer for $110 shipped ...... The Gamma was out of the box long enough to do a parts count . The Alfa was set up and checked against known loads and has run a 100 or so work ups over it with a silly little aluminum and Lexan deflector out in front of it about 2" .
I only use mine for MV so it's pretty easy to keep it below line of fire but there are a couple of otherwise nonfatal line pocks in the shield .
At first having one was "All the Wonders of the Universe" (in your best GP Oz or Robin Williams Genie explaination voice) . Now it is more a tool to validate data for a known value or reach a desired goal . I could still get by without it but it is a great builder of confidence .
