    You need media that can burnish down in the groove.  That's what
    mixed shot is for, with its pins and little ball-cones (the ones that
    look like Saturn).  Sometimes you have to remove the pins from your
    mixed shot because they can become lodged in artwork, and they aren't
    always needed for good results, but sometimes they are necessary, and
    sometimes you need something even smaller, like the teeny pins of a
    magnetic tumbler. 

    The size and shape of media can be important.  I just ran into this.
     We had a closed form that had several large holes going through it,
    and the closed form had some "squinched" areas.  The potential for
    small cones getting permanently stuck was obvious.  Like most people,
    we add new tumbling media to old as the volume decreases (the media
    wears down and becomes smaller). Consequently, there are some fairly
    small cones in our every-day mix (this is usually a good thing).  We
    used all new media for this project and had no trouble.
