It depends how cunning the manufacturer has been, with the full length barrel HW80 Beeman/Weirauch had a design where the .22 version produced very nearly the same power as the .177 from the same internals.
.22 is more efficient but a .177 has a smaller barrel volume giving the projectile higher pressure for longer in a springer
