Hey guys I’ve got the fx impact m3 in .25 I have the stx superior and the stx superior heavy liners and the slug power kit. When I first got the gun I played with the 26.8g NSA slugs and got them doing around .5 inch groups at 50 yards, ive since installed the slug power kit and heavy barrel, tried other slugs (NSA 26.8, 29, 29.5, 33.5, 33.6, 34.9, 38.5, ZAN 33, 35 and the fx hybrids) and not one Would do better then 1” groups at 50 yards trying all speeds from 880 FPS to 1000 FPS used about 3-4 boxes of each type trying to tune. So after spending almost 500$ on slugs now and not finding anything that shoots close to as good as my daystate huntsman regal will shoot slugs with it’s short pellet barrel. I’ve decided to try go back to the pellet barrel and removed the slug power kit to get the 26.8g nsa back to the 1/2” groups. But now with all the same settings I’m shooting at about 1080 fps where as before was only 910 FPS. So I tried to tune it back to factory settings and shoot the pellets and there shooting at 890 FPS on 3, 2.75, 4 bars showing, and reg at 90 bar. But now when I turn my power adjustment wheel it doesn’t change the FPS till I get down to around 3-4 then I get a bit of movement. At 1 it’s shooting at 850 FPS so I really don’t have a lot of range to play with it and I have no idea why. So I tried to go back to the 26g slugs and couldn’t get better then 2” at 50 yards I tried all 16 power wheel settings at 100 bar on reg, then 105 bar, 110 bar, 115 bar. All of them about the same 2” groups. I have no idea anymore what to do. I’m almost ready to sell the impact and just keep using my daystate huntsman, it’s not tuneable really but I get Way better accuracy out of it than the fx impact could dream of so far.
the more I watch tuning videos online the more I realize no one explains how to set the reg. They all say we already know I need more reg pressure so I’ll put it to 150 or they say well I already know I need 135 bar so we’ll set it there. But no one says how the hell you know you need higher or lower? I crank mine up and the speed stays the same or it will drop. And my power wheel adjustments don’t do anything unless your on the lower 3-4 numbers. Maybe my gun is broken? Should I pack it up and return it? Also people say to listen to the valves, I live in Canada you can’t use a silencer here so the gun is louder then a .22 LR I can’t hear anything so I have no idea wtf there talking about. Maybe the fx impact is just a garbage gun without a suppressor? Is it made to shoot with one and can’t handle not having one bc of the vibrations?
Anyways if anyone has a step by step guide on how to tune the gun that would help a lot. Mainly how to tune the regulators in detail not just saying you need more pressure. But why and what are the signs or conclusions to that decision? I Currently feel like the fx impact is just a money pit and considering selling it and sticking to the daystate huntsman. At least then I can count on hitting something when I go hunting bc right now I don’t trust it enough to hunt with it.
