“Quiet riot”?
How about “Quiet arming”? Or, “Quiet target practice”?
Subsonic .22LR and a suppressor makes for quiet target practice. A friend has that setup and tells me you only hear the click of the hammer and cycling of the bolt. A BufferTechnologies recoil buffer for the 10/22 really helps reduce that metal to metal slap of the bolt against the receiver retention pin.
