Im new to regulated airguns particularly the Fx Wildcat. Starting at 250 bar and stopping the test at 160 bar with a 875 fps average, the velocity started to climb. I continued to chrony a clip and half and the velocity continued a steady climb to 903fps. I descided to stop until I get an answer why this is. I was expecting the velocity to get to a certain point and start falling off, but did the opposite instead. Is this normal?

Could be regulator issue. Did you fill the gun really fast? Did you let the air tube cool a little after filling? Sometimes this can happen shooting of a hot fill. Also can be dust or to much grease in the regulator.
How long have you owned the gun?

No, it was filled really slow and it sat to cool for over an hour (had to run errands) However I am curious, will a fast fill damage a regulator and why? Sorry for my ignorance and appreciate the learning 
Oh I opened box 2 days ago.

3% is rather high for a regulated gun. I would call the dealer. A fast fill has no ill effect on any portion of the gun. That can heat the tube/bottle and cooled pressure will be less, but that is about the extent of a fast/hot fill.

I had a similar problem with my cricket. What I found causing this was the hammer spring screw had back out and was set below the regular's pressure. The velocity started out very low and climbed until it stabled for a few shots and then the velocity started decreasing.

Thanks everyone for their replies. I apologize and please allow me to paint a better picture of my concern. First, I live in the USA so I'm not restricted. I did a chrony test last night starting at 250 bar. The regulator appreared normal after 55 shots with the fps maintaining between 867 - 877. I think that's a lot of shots already. Anyway, so I kept going with the test. When it reached 160 bar which was shot 56 (883fps), the fps started to climb to shot 68 (903fps). And that's where I stopped the test. Is it normal for the regulator to climb like this before falling off?

i didnt get a wildcat manual so i have only been filling to 220 bar. are you sure 250 bar is ok?

Under the serial # on the wildcat it says 220 bar but the air reservoir says 230. I fill to 230

You are correct sir! Right next to the serial number, Made in Sweden, on the side of the gun will say the Max Pressure recommended. I think that will be the last time I fill to 250 bar. 48 shots (6 clips) is plenty for me per fill

I'd be interested to know if when you adjust your fill pressure if your shot string changes. Maybe you were starting to get some valve lock. I don't know if thats possible on a regulated gun but it would be interesting to see what it does at the new pressure. Thanks... I'm enjoying the education.

Did another string but filled to 230 bar (as recommended) and ending at 170 bar resulted in a 40 shot count (5 clips) with velocities between 860 - 875fps. The regulated velocity did decrease with a 230 start but not much. If there is a break-in needed on this regulator or regulators in general, I hope to see a lower ES.

please post the actual shot string.
All I can tell you is that if you are new to air rifles, don't try to work on the regulator yourself. It is a mechanical valve really but still can be overwhelming for someone starting out to work on. If you are experiencing issues send it back to the dealer and have professionals look at it.

Oh no, this is definitely not my first airgun. It is the first airgun I owned with a regulator which the FX Wildcats come already installed. Below is my latest shot string using JSB 25.39gr filled to 230 bar and stopping at 170 bar. I did get more shots from a 250 bar fill but I will more likely stick with the recommended 230 bar. Just a reminder from my previous post, this gun is only 3 days old so I have no intentions of opening her up.... well, except to 'OPEN HER UP ON TARGETS'

I may have found my answer to why I get an increase in velocity when I reached 160 bar. Looks like 160 bar is where my gun falls off. Please dont hesitate to correct me if Im seeing this in a different light.

Plus the velocity I am getting with this Wildcat 25 is optimal for shot count and accuracy. I've shot over 900fps using JSB 25gr with other airguns and confirmed instability thru a scope cam with slow motion video.
