That's the latest, copper free, number I believe. The numbers I posted were the ones I've been using since 2017.
We've had copper in our pads for how long? I call baloney on that one, especially since it is a natural material and heavy. Like gold, it's heavier than water and goes right back into the ground. I have seen fish with growths on them at the inlets, presumably from fertilizer runoff. Copper cause this too? I broke a thermometer a few months back and the mercury went right into my skin. Heavy levels of lead do make people crazy but I don't ingest it and wash my hands after making boolits. The people clamoring for all these bans are the same ones who made us switch from paper to plastic and now what? They want us back to paper/cloth bags.
