I have a CFX .22, also ordered from Pyramyd Air, and here are the muzzle velocities my Chrony showed that I am getting with it:
Daisy Precision Max Flat Nose - 666fps
JSB Exact Jumbo - 767fps
JSB Predator Polymer Tip - 756fps
RWS Super H-Point - 740fps
RWS Superdome - 663fps
Beeman Ram Jet - 735fps
Beeman Crow-Magnum - 720fps
Beeman Field Target Special - 662fps
H&N Baracuda Match - 704fps
My go to pellets for it are the Superdomes, Exacts, and Ram Jets, but all of these pellets (save the crappy Daisys) shoot well under an inch at 25 yards.
It also absolutely decks targets, significantly harder than its .177 CFX twin, also ordered from PA.
I also installed GRT-III triggers on both of them, and it is a MASSIVE improvement.
It makes them feel like custom target rifles, and the installation was so easy that I honestly believed that I had forgotten something, but the Word document Bob made up comes with excellent written instructions and high quality photos that told me that I had done everything right.
Unbelievable how a little trigger can so dramatically improve the shootability of an already excellent air rifle.
