Usher CP-63XX owners, have you added Lead Shot?

Thanks for the info, I will get them up and running then decide. Any idea where to purchase the steel shot, if I decide to go that route?

The issue of lead shot being used in speaker stands has come up in the past quite frequently, and I agree with most that discourage the use of this material in domestic applications. In my opinion, it is not worthwhile to use something that has potential hazard. However small it might be, there is risk anyone can be affected, not only to toddlers or small kids. It's like keeping knives and sharp objects clear from infants. The only difference is knives are essential household utensils being used in the kitchen while lead is not. There is a choice of using other safer material. You would never know if there is leakage and lead dust(possibly from abrasion between the lead pellets) may leak out from the stands.

Also, I think there isn't any major differences between lead shot and steel shot, or sand material. I may be wrong, but I will leave it for lead shot users to comment.

Nordost wires used to have this "Lead Free-Protect Our Environment" label on their packaging, for those who might want to know.

I use plated Daisy Zinc plated BB's. They are safe and though not as heavy as lead shot (and not as cheap) they safer and easier to use and clean up when spilled (use a magnet). The plus is you can get them almost any where.

I'd stay away from the lead. However it is still used in some commercial and industrial paints since it's not banned 100%. Lead emits fumes when being heated like in soldering however dust can be inhaled when pouring the shot into the the speakers and a very minute amount could be absorbed through the skin. The body can't distinguish the difference between lead and calcium, so the body uses it as if it's calcium. That's one of the reasons symptoms of lead poisoning take so long to develop. I used sand in my stand.
