Is anyone collecting lead from the back stops at their clubs?
How good/ bad is it for casting?
There is lots of copper mixed in and having never cast before, I'm not sure how that may complicate the process.
I just used an old iron frying pan on a Coleman stove and melted my range lead/wheel weights/water pipe in that and scooped off the floating junk and poured into ingots. Don't do it in your casting pot if you can help it. Ventilate well!Is anyone collecting lead from the back stops at their clubs?

I use Marvelux (from Brownelles) when rendering range lead. We usually net 6-700 pounds per year after the rendering is done.
I use a separate pot to render with a propane fired burner under neath it. Ladle from the pot into ingot moulds.
Each full pot equals 60 pound of ingots. I use an RCBS dipper to cast one boolit right before I fill my ignite moulds. So that I can test each batch for hardness.
I’ve had batches as high as 23bn and as low as 14bn. Average is 18bn
Before I started using marvelux (we used to use beeswax and sawdust to help dross the mix) the best we ever got was 14bn average was 11bn. And we’ve rendered several hundred tons of lead from the range... it’s been open since the 60’s and we mine the trap at least once a year..... back before my time, in the 70s and 80s it was a 3-4 times a year task as the volume of shooting was quite a bit higher....
I don't understand how your lead can be 18 BHN. I hardly ever see more than 12 BHN, usually less. I think the average is about 10.5
Marvelux is a flux and does not change anything to hardness. There is something wrong in the way you check your hardness. There is no way range lead will get more than 10
