If you're married, you don't even need to ask that question :-)!
Re: pellets for CFX. Under 25 yards or so, mine still likes JSB Match Diabolo S100. That's the heaviest of the JSB Match pellets, advertised weight is 8.26 gr. For everything else, the JSB Exact, 4.52 head diameter, used to be the best. Lateley, seems like Superdomes are better. That answer is qualified for a couple of reasons. I've been doing stuff to my gun, and I'm limited to a 10 yard range right now. And unless you're shooting a 10 meter gun, that's just not enough range to really know what's going on.
Now here's an answer to a question you didn't ask, and it might even be more helpful. My CFX hates anything with a point, safest place to be with a pointed pellet loaded is directly in front of the muzzle! Okay, maybe that's a LITTLE overstated, but you get the idea :-). Despite many other's claims to the contrary, it doesn't like Crosmans or Beeman FTS's. Crow Magnums are okay out to about 25 or 30 yards. Pretty much anything under 8 or over 9 gr. is a waste of time. HTH.
