Yes, duster is lower pressure, and therefore, produces lower FPS in guns.
Its what Japanese guns are designed for, as they're laws prohibit guns from firing over 1j
However, many Japanese guns (TM for example) usually perform fine, at least for a while with the higher pressure, propane.
Not sure about other brands, only GBBs i have ever owned are all TM
