I have done and I found them OK up to about 800 ft sec which equates to 16 ft lb. Over that and it is JSB Heavy all the way.
Remember however that the black art of pellet/barrel matching means you have to test your particular barrel to get the best results. What works for me may not work for you although the general rule holds good that if you increase the power heavier pellets tend to work better.
As a side issue I once tested a .177 FAC Rapid that spat out 8.4 grain JSB pellets at insane supersonic speed-around 1100 ft sec with pinpoint accuracy. I only turned it down because the air economy went to hell in a handcart. Oh and the noise.
