EDgun Chrony String
I got the Avg. FPS from a Combo and the rest from a Chrony
JSB 18.1gr
Avg FPS = 904
ES = 17
SD = 3.46 for the first 32 shots
SD = 5.29 for the last 15 shots with the last 2 shots being slow due to
falling off the reg…..
So total full shots from one fill was 45….
The FPS being recorded by the Chrony was an average of 926… 22FPS
higher than the Combro @ 904FPS…
I have also found that the gauge on the EDgun is quite a bit lower than
the gauge on my SCBA tank….To get the EDgun gauge to read 200bar, I
have to fill to 220bar/3,200psi on my SCBA gauge

Did some testing and tuning this morning… To make sure I wasn’t
waisting my time, I clamped the gun in my bench rest and started
shooting with the Combro attached….. The gun was showing the potential
of being a tack driver but would act up now and again and start spraying
pellets all over the place @ over 900FPS so I started lowering the FPS
about 10FPS at a time…. I am now set at about 1/2 turn out from the
factory setting on the main spring adjustment screw….
This is 10 shots @ 65yds with the gun set at an average of 890FPS.

That ain’t gonna cut it.
This is 10 shots @ 65yds with an average FPS of 876

And this is 10 shots @ 80yds with an average FPS of 876
