hi. wanting advice please. I've got the fx impact FAC in 177 and. 25. I've been out today and tried scoping in on a pellet tin at 50mtr and 60mtr ..the first shots hit both distances then I missed the next 8-10 shots.I've upgraded most parts . I have the stx superior. 25. I've put the duel hole transfer port on and the power plenum and I'm waiting for the huma 110-160 bar reg. but at the minute my reg is maxed out at 105bar . I just bought the fx hybrids slugs in .25 running at max 292mps just over 50fpe . but accuracy isn't there. could it be that I'm maxed out on the reg. or could it be something else. any advice appreciated
