Ping/twang from fx streamline /filling without moisture chamber by mistake

Ok so this past Friday I got my fx streamline!!!!!!!!!!!! Laminated. So I know that this has probably been cover 100s of times but it's happening to me and I don't want to harm my rifle. After I drop below 150 bar/37 full power shots, a noise/twang comes from my rifle. What does this mean, will it harm my rifle if I shoot past this point. Now from excitement/by acident, wanting to shoot my rifle asap I pumped up my rifle without the moisture trap and didn't realize until my third fill. Since then I have attached the moisture chamber and filled my rifle. Is it Ok that I filled it without the moisture chamber or to I need to have my rifle checked out. Sorry for the lengthy post thanks in advance.
 
Don't worry bud, you will not any harm at all :)
And about the difference in the noice, have you checked the velocities though a chrono? If you can't see any difference just keep shooting till you pass the reg pressure (check with chrono). I would not get worried of the sound difference unless you can see something bad in the shot string at that point. We are talking about 150bar so it's probably that that's the reg pressure in fact, and if it is, just refill at that point :)
Cheers

thank you menttalliist I don't have access to a chrony aso of right now ohh and it's a 25. Cal probably should have mentioned that. So I don't have to worry about filling it without the moisture catch by accident? I wouldn't be asking again but I didn't quite understand your answer. Sorry lol hopefully I don't look to unintelligent posting this lol
 
Often called "Ping" in nairguns, I have ONLY heard this on a regulated rifle ( & haven't seen a streamline) after the rifle fell OFF the reg. , and have I read FX should not be fired below reg setting? Naturally a shot should be fine but "I" would refill the moment I heard the "ping".

One would think it shouldn't actually hurt anything unless fired very low, or no air but why chance it.
