I’ve been shooting the JSB 25.39g through my Wildcat Compact with great results. Today I decided to try the JSB 33.95g. Here are the chronograph numbers! Can’t wait to put this out to 50 and 100 yards
FX Wildcat Compact 33.95 JSB

Nice results and thanks for sharing. Which chronograph are you using? I just ordered the Comp Electronics DLX from PA. Getting the indoor light kit from from Amazon though since it was $20 less than PA.
Alos, which regulator does you gun have? I bought my Compact back in March 2019, and not sure if it has the old FX reg or new AMP reg. Is there an easy way to tell? I’m pretty sure there is something wrong with my reg because I’m getting spreads of 45 fps (830-875) shooting the 25.4 gr JSB King’s. For comparison, my unregulated Daystate has an extreme spread of 9 fps.
I called UA yesterday and they think my hammer spring adjustment nut came loose. I have to say I’m a little dissappointed in FX quality. You shouldn’t have to start tinkering/fixing a brand new $1400 gun after only a couple months of light indoor use.

Isn't mid 700s pretty low to pushing the king heavy? My impact is pushing them 850 and I still think that's pretty low cause I can see my pellet doing a arc at long distance. It's best to push the king heavy at least 860-900 fps to get the best accuracy.

Thanks. I’m using the ProChrono Chronograph from Competition Electronics. You’ll definitely need the light kit. I got my compact when it first came out so I know it’s the old regulator. The hammer spring adjustment is pretty simple but it’s best to get your chronograph first so you can somewhat tune it

Well, I know how to get to it - basically take the stock off and its located at the back of the block. From there I’m not sure. CW to tighten, CCW to loosen?
I’ve read that a person should make 1/2 turn adjustments to find your “peak” then fine tune from there. If the peak isn’t providing desired fps, then adjust regulator output and try again. I like to mark the nut somehow before turning it so I have a reference. Once you find the sweet spot, how does one make sure the HS nut stays put?
I looked at my air tube earlier and noticed a little rubber ball on the LH side towards rear of air tube. Is the reg adjustment screw under the rubber ball?

I'm in the same boat I bought a compact spring of 19 it's my first air rifle and I think I have reg creep. I need to do so.e testing to really know but seams like my first couple shots in the morning are a lil different after sitting from the day prior. after a few shots it seams to get back where I like it. I think I might just go Huma and be done with it .

I’ve noticed the same problem with my gun. My first shot after letting the gun sit overnight is around 40-50 fps low, then starts climbing from 830 tp 875 over the next 20 shots. Ernest has a vid about regulator creep but doesn’t discuss any solutions yet. Reg creep on FX guns seems to come up a lot on the forum. Solution seems to be - replace with Huma.

For everyone’s information that shot string was shot after 5 days sitting. It was put away with the air tube at 230 bar and when I pulled it out it was at 230 bar. So if I have creep it’s still shooting at a 9psi spread with a SD of 2.
Sounds to me like a regular rebuild or talk to FX USA. You can talk with Earnest Rowe personally.

I understand that I’m just stating how mine will sit with no creep in the regulator and how I store it

well that's not what I was hoping to hear
i have heard that it fixes the problem sometimes. but some other problem must exist. the Huma solved my consistentcy and shot spread issues with the original FX reg. but it still acts the same if i let it sit overnight , i need to shoot off a couple shots to bring the fps up. then it will stay consistent the rest of the day.

Hi Jbravo103,
I have the same problem with Impact x, it should be AMP reg, i need about 3 shots to come back to normal speed from lower, it happed not only over a night, it happened when put the gun for several hours to me.
