About a month ago I bought 4 buckets of scrap lead. 3 were wheel weights, one was recovered range scrap, or so I thought. I have already sorted & smelted all the WW. Upon pouring out the range scrap into my smelter, at the bottom is a bunch of diving weights, and what appears to be fishing net weights. Also there was several ingots marked Ohaus. I'm melting the fishing net weights with the range scrap, but I separated the diving weights & Ohaus ingots until someone might know what they are, and OK to cast with. Thanks...Shooter
