FX Impact upgrade barrel or get wildcat

So after getting my Wildcat Mk1 in .25 my Impact .30 s now gone. Sold it. My Wildcat. 25 Standard is sooo accurate and powerful enough ( 52 fpe w Jsb 33.95s) that I just wasn't shooting my Impact as much. I did also pickup a .25 Taipan Veteran shorty so just enjoying both. I still do prefer the Wildcats side lever but both of these guns are outstanding. 

Please elaborate on your Wildcat .25 cal shooting at 52 fpe.

My WC .25 cal tops out at 45 fpe.

Mine shoots the Jsb 33.95 gr at an average of 834 over aprox 38 shots from 230 bar to 140 bar. It shoots the Jsb 24.39s at a 942 fps average .
