Don't wish to be out of line here so take this for what it's worth. I've made a couple tons of bullets from alloy containing 6% antimony. These bullets were fired at one of the Linebaugh shoots into their test media. They bent, they expanded, etc but they didn't shatter. We've laid them on steel & hit them with different weight hammers & they looked alot like bubble gum in various states but they didn't shatter. It wasn't bone chilling cold though. BTW they tested 15 BHN.
