Hmmm, Looks like this lead may have started out as plumbers solder, used in joining cast iron pipe for instance, oakum and lead joints, but being a very soft and handy size, it got cut and used for everything...duck decoy weights makes good sense, I am finding this on the edge of an island in the sound. I have found pieces in the woods too and it may well have been carried as scrap to melt and pour in bullet molds. I am going to hold out for some more ideas from you-all. This is such a good forum. Thank you.
