Hello everyone! First post and I'm glad to be here. I've learned so much from searching and viewing posts on this site. I've been shooting .357 into backstops of wet sand to view the expansion and I considered saving the soft lead to recast. I removed as much sand from the surface as I could but I'm wondering how it will act when I melt it? Will the sand sink or float for removal with flux? The last thing I want to do is put it down my barrel. Thanks
