Do you have a heavy liner? If JSB 18s wont shoot well in your liner either you dont have a standard STX Superior or you have the worst luck on the planet lol.

FX Help with tuning Wildcat down
- Thread starter bchannell
- Start date
OK, guys. FIRST off thanks for all the help. Sometimes you just need another head or two, I really appreciate it.
The MRD's are something to behold indeed. After sighting in at 33 yards, and then taking some potshots at 50 and 70 yards, I took a long break, ate lunch, and rested, so it was a couple hours later, when I shot this 100 yard groups off the bed of my truck. You can barely see the 100 yard target just above the bag and between the two trees. Not too bad at all for the first 5 shots out of the gun at 100. I have a feeling the one stray was because the wind blew a tree limb over the orange aiming dot and I guessed at it, but I thought I got it...close enough for me.
Super gun, great trigger (I tuned it a bit) and just fabulous accuracy. This will be my pellet for this rifle. I may try some 21gr pellets, but I kind of figure you have to get up in weight and power to make this thing shine.

It's a heavy liner. I have a superior pellet liner for my Crown I'll try later, but for now, I'm good with this.

In this platform the 500 mm barrel would really be the spot for 18 gr to shine I would think.

I'm still trying to figure out the ballistics. The calculators call for ~4 mil drop but only got 2.5 mil drop, which is good.
I had to adjust the bc up quite a lot.

Hi, I am pretty new to pcp. Hope someone can advice what should I do. Wonder why same reading when I turn back wheel 1-7
Was trying to tune my fx wildcat mk3 compact bt. Watch some video and tried to tuned it. But I am ended up with same reading when I turn the back wheel from 1-7.
Pellet : jsb .22 18gr
Mod : huma tungsten hammer with huma spring, huma probe, huma transfer port v2
reading : 600-700 the changes only noticeable when I adjust the back screw, which I tried 1mm 2mm 3mm 4mm 5mm 6mm
Is it because I should not do it with pellet?

For an 18 grain pellet a tungsten hammer is too much for it unless you use very minimum power adjustment and 150+bar. The tungsten hammer is for around 150 bar and high energy levels. You should be able to send a jsb 18 nearly if not entirely supersonic with stock components.

You have way too much hammer for your use case. I would lose the hammer weight and consider putting the pellet probe back in. You are set up for slugs currently. I found the pin probe did not seat the pellet beyond the transfer port on my Wildcat, partially blocking the airflow.

Thanks for advice, in that case, I shall try to put back the stock spring, hammer, and probe (if spring + hammer doesn't work) to try again

18s and even 25 grain monsters should be fine stock. If it's not enough then perhaps a 14 gram hammer. I made some just above that weight for my buddy to shoot 23 grain slugs with the stock spring at 150 bar. Hammer swaps are soooo nice and easy on that platform.

Do you have the slug style pin probe or the Huma pellet probe? Tungsten hammer weights have caused a lot of people problems. If you decide the stock weight isn't heavy enough you can always throw in the Huma spring later. But as pointed out above, a stock compact should have no trouble pushing standard weight pellets faster than you need.

huma-air.com I am wondering how this pellet power tune kit works for those reviewers.
Aside from this, is it normal that I can feel small amount of air leak on cheek piece after pulling the trigger?

Raise the press on the sec regulator above 105 bar and check speed .
But first replace what has been changed with the originaliteit parts

Ok their high flow pellet probe is my favorite. It will improve your speeds a little bit over the factory probe but still squarely seat all ammo types into your breech. I would leave that in and install the stock hammer weight and spring.I got huma pellet power tune kit which come with 13.2 and 14.5 gram tungsten hammer.
