    It will only be whisper quiet with sub-sonic loads.
    A silencer only cuts the noise of the muzzle blast.

    When a bullet breaks the sound barrier, it still makes a pop.

    But then the lead hits the target before the target gets to hear it and flinch. It goes Pop, but it's too late at that point.

    FYI:

    Rewind to 2001. It was my Junior Auto-Tech year in HS when we had a "field day". Basically, an all day BBQ thing at my Vocational School. We also had a local car stereo place come and had a "sound off" (kids competing to see who had the loudest stereo system).

    Well, my class decided to bring out the early 80's 3rd gen we built and see how loud the exhaust was. Did you know open headers on a SBC at 6500ish rpms would measure at around 140db (IIRC). That was when they stuck the mic underneath the car near the headers.

    I'm just waiting for the photoshop of Tommy in tactical gear with a silenced M4/M16 and running squirrels in the background. :)

    No need for a silencer in that situation.
