    Daystate X2 R advice

    Hi there,
    I wonder if any Daystate X2 reg owners out there can give me some advice. When I fill the rifle up to 220 on the rifle's buit in gauge and fire around 20 shots, the pressure drops to around 185. Is this normal? Also the first shot at 220 was bang on 12ft but the next half dozen or so dropped to 11.75 and 11.5 ft lbs. I thought as it was regulated it would be the same for each shot. Is it dangerous to fill it right up into the red zone?
    Does anyone know at what pressure the power really drops off at. Dont want to go out to shoot something and find the it is under powered.
    I might add that it does shoot very well and is making one hole groups at around 20 meters. Just curious about the variations in shot power etc.
    Many thanks in advance.

    cheers

    I'd be much happier running my rifles at 11.5ft/lb and no higher.

    are you sure its regulated?

    My x2r has no gauge, I thought the regulator takes the space that was used by the air guage.

    I have an X2 Regulated, no gauge on mine same as the last poster says, that is where the reg fits, usually fill it to 200 bar. If I fill it to 220, first few shots seem erratic

    Cheers

    As above it sounds like you have got a standard X2 and not a X2R.

    Always use the gauge on your bottle and not the gauge on the rifle when filling as the gauges fitted to rifles etc are there to act purely as a guide.

    My X2R also has a pressure gauge fitted. I fill to 220 bar, not noticed any problems on paper targets. Recommended servicing is every 2 years.

    I think the OP's rifle must be regulated. If you filled an unregulated X2 to 220 BAR it probably wouldn't fire! Or if it did the power would be very low.

    Most regulated guns need a few shots to settle after filling.

    I personally would get it looked at as in my opinion the power is too high.

    Hi Guys,
    I e mailed Daystate with the serial number and they confirm that is a regulated X2.
    The first shot was 12 ft lbs then quickly settled down to 11.5. Used an FX pump which gets very hot so that might explain the slightly erratic readings for the first few shots.
    Did drop from 220psi to 185 after 20 shots though.

    cheers

    Cooling air can give quite a large drop in pressure as it returns to room temperature . If I fill my rapid bottle quickly to 220bar after sitting for 10 mins the pressure can drop down to less than 200 bar .

    Make sure you have a true fill by pumping to 220 bar then let the gun sit a while for the air to cool than top back up . This may take more than one top up to get a full 220 bar fill .

    I had an X2r .177 (no pressure guage) and it gave 65 shots from a true 220 BAR refill, as nutshot describes above, at 11.4 ft/lbs. At this point it came off the reg and provided a few more shots before the point of impact would start to drop and the chrono confirmed this.

    The first sign that the shots are no longer regulated is usually a change in the sound of the muzzle blast on firing. My Mk3 is the same. The pitch and duration changing from a sharp crack to a slow fart.

    It was around the 90-100 BAR mark, as indicated by the pressure at which the valve opened during refilling.

    The first shot after refilling can differ, and the Daystate manual recommends either dry firing or a clearing shot.





    The max fill pressure on mine IIRC was 232BAR (the figure on the barrel shroud)

    Many thanks guys.
    All good advice. I did notice the chrono figures reading lower around the 100 psi mark.

    Much appreciated.

    Do not let your pump get hot, rest every 20-30 strokes or so. Overheating will kill the seals and the clack valve.
