Yea...the GAMO brand does live up to it's velocity standards...
I've chronographed my GAMO Magnum .177 using a ProChrono Digital ... 980 to 1000 fps was the norm.
The Competition Electronics ProChrono Digital Chronograph measures velocities between 22 and 7000 feet per second, records 9 strings of fire with review of 99 shots each and computes statistics for each string (high, low, average, number of shots, standard deviation and extreme spread). Other features allow you to delete the current shot or string, and you can switch from standard to metric measurements. Chronograph includes plastic diffusers, 4 rods and is powered by a 9 volt battery (not included). This chronograph has a mounting hole thread for a ¼x20 mount. Be careful to prepare adequately for windy conditions.
