Well, it's sure interesting. To fill a PHB with shot like that seems contraintuitive. I recall one of my first toys ever (OK, I don't actually recall MINE... but my daughters maybe...) was a RATTLE.... which consisted of a ball filled with beads that.... rattle.
Would love to actually get the downlow on this particular feature from the engineering group at FoMoCo. I'm sure it's very interesting indeed.... after all, you don't do such things... that cost money to be sure, sans a damn good reason.

It's more than just adding mass to dampen vibration. If that was all then just weld some solid round stock inside the tube to keep noise down. No the bird shot sort of floats or bounces in the opposite direction of the movement of the bar. This cancels out high frequency vibrations. The same method is used to help eliminate ground resonance on certain models of helicopters.

Yes Hvb is a vibration. Like I said if it was just about mass then a piece of round stock welded into the tube would suffice. But the bird shot bounces and cancels out even more vibration but at a trade off of causing a little rattling. Therefore it is about the FLOATING mass rather than the solid mass. Hope that clarified the confusion. Yes location within the tube affects the frequency that is canceled as well as the post above mentions.
