Just purchased a chronograph (ProChrono Digital, after reading lots of reviews). Seems to work well, I'm happy with it. I'll be doing some experimenting and wish to share the data. I understand the parallax issues with indoor lighting that can cause a systematic error of falsely elevated velocity readings. I am using the light kit indoors for testing in an otherwise dark room.
The Beeman P17 is well known for its low price point, fair trigger, and surprising accuracy. There are several excellent threads elsewhere discussing this airgun e.g.: http://www.gatewaytoairguns.org/GTA/index.php?topic=49115.0
I have been curious if it lived up to its reputation. It is marketed as a 410 fps pistol. I have a stock P17 with less than 200 pellets through it....and a shiny new chronograph. I need wonder no longer: (I'm shooting JSB Exact Express 7.87 gn pellets)
