    SCUBA Tank Refill in Australia

    Went to fill up my SCUBA tank this afternoon, it seems there have been a few accidents with old/damaaged tanks being refilled. SCUBA tanks now need to be certified every 12 months, regardless of their intended use. We used to get away with filling them for PCP use, but no more. Tried to talk...

    FX Impact Shot Recovery Time

    While doing some testing to resolve differences in velocity, I noticed full recharge to reg pressure was not instantaneous. I've found consistency improves if I wait 5 seconds, watching the gauge after a shot it creeps back to full reg pressure. I didn't notice this before I installed the FX...

    Tuning my FX Impact

    Below are the setting and results from testing range of setting on myFX impact, with a .25 cal ver 1 barrel, 33.95 JSB Exact King Heavy pellets, 125 bar. I notate ring is one complete rotation of the valve adjuster. The extremely low velocity on second set results from closing the valve...

    An FX Impact Valve Stopper tip

    Someone may have already covered this but here goes. The adjuster has some groves to show changes went it is rotated. My eyes find it very hard to read as things are dark in that area of gun. Remove the adjustment nut/cover and paint each grove with whiteout or white paint. Makes it much...

    Does anyone use other gases than air?

    Met a chap who has a large cylinder of Nitrogen in his workshop, no longer used in his business so he now fills his PCP with Nitrogen gas. Just wondering if anyone else has tried it and results. Took my scuba tank into be recharged, guys wouldn't do it until it has been pressure tested. Scuba...

    FX Impact Tuning - Power wheel versus Valve Spring adjustments

    Still coming to grips with PCP things. My days old FX x Impact .22 Cal, with the hammer wheel at high pills nearly punches through 2mm still at 10m, 958fps with JSB 18.13gn. A bit more than I need for birding. Wound the hammer adjuster wheel to Min, velocity dropped to 838 fps. Running at...
