The other posters are correct, everything from the $124 Walmart Shadow 1000 to the 890 used the same powerplant, trigger and barrel, despite the tremendous difference in price.
With Crosman Premier 7.9gr (sometimes called CPL) - which is a good, all-round pellet that's not horribly expensive - a new one should do right around 910-920fps. After break-in, it could go a bit higher. Sometimes an oinker gets through that won't break out of the mid-upper 800's. But that tends to be a rarity.
Accuracy? Gamo claims about .4" CTC at 10 yards with their Match pellets - but frankly I don't think that Gamo Match pellets are that good. Using a single-point rest and the open sights, I can usually do better than that with my Shadow or my 220 using CPL's, and I'm not a very good shot. I'm guessing that .2" CTC is within the gun's capabilities.
