FX Wildcat .22

Gentlemen:

Thanks all for your time and kindly input in my post. Some considerations so far, specifically related to FX Wildcat .22:

1 - I know the max pressure is 230BAR. It is written on the side of the Wildcat cocking mechanism as well as I said in my initial post. 

2 - I don´t know yet the min pressure. I will chronograph my gun and I will indirectly found out. I am looking forward to do it this weekend. However, I was hoping somebody had this info from FX or other sources. Here is what I have so far and again I thank the members of this forum on their answers: 

* Tominco suggests that I shouldn't go below 100BAR. Noted.
* Scoth_MCT suggests 120BAR.
* bent goes to 110BAR min.
* AOA have sent me an answer saying that the min pressure would be between 103BAR (1500PSI) and 83BAR (1200PSI)! By the way this is the most strange answer...
* FX does not answer my emails and I gave up them. Their website does not show either the min pressure.

3 - It appears the regulator is set to 140BAR. There is no way I can check that. 

When I am hunting, I just look the gauge to see the min pressure. I am too scatterbrained to count how many shots I did! Also, it is good to know before testing your airgun what is the factory parameter.

I am continuing my investigations...

"AirgunnerDK"If you go to FX's webpage and look at the part list, you will see that the regulator is set to 140 bar.

Thanks AirgunnerDK! 110BAR .177 and 140BAR .22 & .25. 

Thank you very much parallax. This is exactly what I was looking for. It seems 110BAR is the answer regarding the min pressure for the Wildcat .22. I will do my testing on this weekend and will share later my data to compare with yours.

I just have one doubt. In your first chart I see the pressure in uneven numbers instead of rounded ones. Were those numbers your best guess when reading the FX gauge or did you install a more precise gauge for the testing? I like the shot count too. Interesting!

Thanks again. Very pro info! 

Thanks. I will do the same to keep the standard you have used.

Gentlemen: I filled my new .22 Wildcat for the first time and shot around 30 pellets. Then, I refiled again to 230BAR and started to chronograph it. 

Here are my findings so far: 

Pellet: JSB Jumbo Heavy 18.13 grains
​
1st Magazine: 230BAR to 201BAR (29BAR variation) 8 shots
2nd Magazine: 201BAR to 187BAR (14BAR variation) 16 shots
3rd Magazine: 187BAR to 161BAR (26BAR variation) 24 shots
4th Magazine: 161BAR to 159BAR (2BAR!!! variation) 32 shots
5th Magazine: 159BAR to 143BAR (16BAR variation) 40 shots
6th Magazine: 143BAR to 130BAR (13BAR variation) 48 shots
7th Magazine: 130BAR to 116BAR (14BAR variation) 56 shots
8th Magazine: 116BAR to 108BAR (8BAR variation) 64 shots
Last shot: 108BAR to 100BAR (8BAR variation) 65 shots 

For 56 shots or 7 magazines here are the data: 
Average velocity 878FPS
Max velocity 892
Min velocity 853
Spread 39.37
Standard deviation 6.99
Energy 31.1 FPE 

For 65 shots from 230BAR to 100BAR: 
Average velocity 875FPS
Max velocity 892
Min velocity 837
Spread 55,77
Standard deviation 11.13
Energy 30.8 FPE 

Some initial conclusions: 
1 - I am confused with air usage between magazines. In my mind they should be similar to each other.
2 - I find 7 magazines or 56 shots as the optimum number of shots for my gun. Easy count for hunting.
3 - parallax have done the same and got 11 magazines until 113BAR against mine 8 until 108BAR. I don't understand such variation between the two guns... 
4 - Min working pressure for me so would be 116BAR. I will shoot now to get used with the gun, start making groups and understand my reticle. I will repeat the testing in a couple months. I think my gun needs to work and break in.

I loved the Wildcat. It is light, ergonomic and very, very precise even for a mediocre shooter like me.
