Yes, some people do find they shoot fine in standard 16"-twist barrels, though how "standard" the barrels are might vary among manufacturers.
Agreed about the heavy bullet. Even at reduced velocity it must be spiking the pressure to some degree to get that lump moving. It's basically a .22 Short firing two 29gn bullets instead of one, without much velocity reduction. Perhaps it's reduced to .222" as it has so much bearing surface?
