Reply To: FX Impact Velocity Data
For,the Canadian model Impact .25 and .30 caliber the shroud is fixed not telescopic and measure 28.5 inches long.
I got it in last September in 2016.
My regulator gauge show 151
With valve showing 4 lines from factory setting
Max power i got an average of 887 fps with JSB 34 grains MK II
At 75 yards I have .5 inches grouping quite easy.
I dont have spiralling or so.
On 16’shots I sometimes have 1 flyer. Not all the time . Most of the time I have,16/16.
I will shoot the .30 caliber in April once the winter is over using JSB 50 grains pellets.
