Looking for a 25 cal pcp for hunting.....

Congrats on your FX Wildcat! It'll be a while till you purchase another airgun 

A lot of guys I know swear by the Sumatra. I would recommend that if your budget allows.

If you all are hunting in rough terrain or places where your AG is going to get scratched or possibly dropped (like I did when I stepped in a leaf covered hole) I would get a .25 Marauder like other members suggested.

In real hunting situations high shot count is not a game changer. Sixteen good, accurate shots are what I get out of my .25 Marauder. I have no problem killing squirrels at 50+ yards with it and have dropped a pest coon at the same distance(head shot). Since it is a dedicated hunting AG I camouflaged it to my hearts desire in Tiger Stripe using GunSkins. A sub $500(with coupon).25 cal repeater that is relatively quiet not pellet fussy and is capable of 1/2" groups at 50 yards is tough to beat. It goes places I wouldn't dream of taking my .25 RAW HM1000X.

FX Royale 500 in .25 will pretty much take out any game/varmint you can aim at. 
With a single shot!
All day long.
