Need help to identify my FX Wildcat .25

[Jibeji]

Hello,
I have bought an used FX Wildcat .25 which has not the powered I was expected.
As you can see on this picture, the hammerspring ajuster has no action, as the spring is not long enough to reach the thread :

I've first imagined to change the hammer spring, but while reviewing the parts list available in the exploded view to identify its reference, I realized that there are 3 different models:
- HP
- 12 ft/lbs
- 10 joules

Would you please help me how identify which is my model so that I can order the needed parts ?

Hi Jibeji, the hammer spring doesn't have to be that long, in fact as its right now is perfect. Remember fx guns have free floated hammers so the spring and hammer are never under tension while the gun is not cocked. If the spring was flush with the action, the hammer spring tension adjuster would compress the spring and hammer towards the valve.
What kind of power are you getting?

Hi,

I don't have a chronograph yet, but the drop at 100 meters is about 1 meter with JSB 25.46gr instead of half a meter. 

Thanks for the information Menttaliist. So I guess the problem is elsewhere...

Edit: do someone know the size of the full power spring? So that I will be able to compare with mine.

You really need a chronograph, if you have a smart phone you can download an app for it chronoconnect I think it's called. That will get you on the right track.
100 meters is a goal? 25 is the starting point in my experience.
12fp is UK If that's where you are that's the one. HP is here I'm thinking.

Hello,
After adding some washers between the nut and the hammer spring, I can get 880 fp / 43 ft/lbs.
Not that much...
