FX Impact MK2 .22 700mm settings. When I started the tune I thought the regulator was at 110 bar. I guess I was mistaken on that. Five shots in the group but I count eight total. One left edge, one at the lower right knot fence wire (yes I did aim for it. Lucky hid maybe). Wind that day was variable as low as 3 and high of 16 mph, but around 3 to 6 while shooting this.
Hammer spring PW MAX = 16.60mm
Trim knob = 7.82mm
Monster 19 position PW = #3 available at Utah AirGuns
Regulator = 98 bar JSB 18.13 = 904fps PW#3
