Zinc buckshot and slugs - ?

[Saxmann10]

I have a lot of zinc ww. Have anybody tried casting zinc buckshot or slugs. Would lee
Molds work for this or would the zinc destroy the mold. It would be for 12 g shells

for buckshot too light (62% weight of lead), for slugs ok depending on what you're doing. Here's a long thread, success achieved finally.
