Hello, so I have shot my wildcat around 1400 times with jsb 25,39 gr and jsb 33,95 mk2. I have mtc 5-30x scope and gun is precise until this strange little string happens in middle of shooting. Pressure readings from weapon gauge, which I believe is telling around 8 bar too much. 25,39 gr 220 bar-200 bar Average 890 fps 10 rounds. 200 bar-170 bar Average 896 fps 18 rounds. And now it gets weird, following shots: 904, 904, 900, 850, 850, 861, 875, 881, 884, 887,897,904. pressure after shots 154 bar. And after this short string of chaos I can keep shooting 16 more shots with good accuracy. This same peak happens no matter which pellet is used and POI will change 20 mm right and 10 mm down at 63 meters/69 yards. Grouping will also open from 10 mm to around 17 mm. I had 4 min break before shooting these 850 fps shots, so I assume its regulator creeping or its just set really high and this is the point it no longer regulate. Without this problem the gun could fire 55 precise high power shots per fill! Please help
