rws 350 feuerkraft pro compact AVERAGE FPE

[Jringe1109]

hello all, this is my first post. ive recently purchased an rws350 feuerkraft pro compact in .22, i do not have a chrony but i feel that it isnt shooting as powerfully as my 350p magnum. does anyone have a pro compact and if so what are your average fps/fpe with different pellets.
i've been using jsb jumbo heavies/kodiaks/cphp/rws super points...
thankyou

also has anyone installed a vortek kit in this particular model if so please post outcome/results

p.s.
my 350p is averaging 860 w cphp tested on friends chrony and it shoots straight thru 3/4" plywood @10 yards. 350 pro compact does not penetrate thru board even at point plank range. should i take a jump and order the vortek kit?

they very allot in velocity! from 800 to 875fps!

i put the vortek kit in my 350mag clone[the ruger air mag.177cal.power increase and shot cycle smoother,and much easier to cock,completely different gun after the tune,much better
