    Just trying to explain the graph and enlighten those who have not delved into Sub/Trans/Super sound problems. The graph was actually made in Finland
    for explanation of the noise factors at the gun range and what a suppressor
    on a firearm could eliminate and what it couldn't.

    You did well on that to be sure, but as learned from McCoy and Vaughn, it ain't as simple as A-B-C. Too often when graphics are presented to illustrate a particular factoid, there be more there for the taking if one has a broad understanding. Too many shooters are not educated on many of these issues and thus leap to erroneous conclusions.

    One of the photos you posted illustrated the oddities as well as anything. It was indicated to be subsonic, yet had the shock wave...on the base, and not the nose. One of those "Oh no, Mr. Bill!" moments to some I suppose.

    Just lending a helping hand as it were.

    Are you refering to this picture?


    Remember you are looking at a fixed frame and may not "see the whole picture"
    the "bow" wave of compressed air may be far enough forward as to be out of the
    frame.

    I always enjoyed these types of photo's

    The fun will be when we design a projectile that's 45 caliber but with a nose
    to make it's sonic boom as quiet as 22LR supersonic

    That type of imagery is quite informative.

    Yes, that was the pic I referred to, point being it is M0.98 and has a shock wave. It isn't a on or off thing, this "subsonic" world.

    Shot my 1911 with a GemTech 45 suppressor on it using 1150 fps defense loads today. Quieter but you still need ear plugs. Suppressed is NOT silenced ! No 458 "thumper" will be that quiet unless way subsonic.

    Is that a 9mm 1911? 1150 is pretty fast for a 45acp. Either way, subs from a bolt action are completely different than subs from a semiauto pistol.
