Hi Nation! Just new here maybe pros or anyone that has knowledge can help me out with my prob somehow. I have an fx impact and im having probs with the poi at times. From 240 to 190 poi seems consistent and great groups half inch @100 yards if i do my part then after 190 to 140 poi seems to drop atleast 3 mil dots but with same groupings. Its .25 cal with extended shroud. Idk the fps but im thinking its around 850-900 atleast because i can hit pigeons @150-160yards with no problem and no wobbles or whatsoever. Everytime i shoot its with the extended shroud. Im just confuse why it shifts like that even if its on regulator. Anyone can help me fix this problem?

First you need to run it through a chrono, no point in guessing when it comes to fps. If the chrono shows a drop in fps at the 190 mark despite what fx´s faulty gauges says, then something needs to be done to the regulator. i also really recommend getting a better gauge (larger and more precise) for setting the regulator. Then mount the original after and ignore it, they are anywhere from 5-50 bar off. My own is 10 bar off.
Get a full chrono string from 250bar to around 150bar (if FAC), and note pressure when/if there are more than a few fps difference.
