I only have the coated pellets in .177 cal. Don't think Beeman makes them in .22 cal. Out of my friend's CFX, the .177 cal. coated pellets are grouping 1" at 35 yards. Mind you, his CFX still has the stock spring and hasn't been tuned (which I will have to do when I go visit). I have not shot the coated pellets from my CFX with a gas ram yet. I plan on doing that tomorrow.
