These are very hard cast ingots made especially for hard bullet casting. Rifle, high velocity, magnum, etc. They can be softened simply by adding pure lead. If you like to pour your own, this is for you. Drop these directly from the mold into water then age the bullets a couple weeks and you will get bullets well in exess of 20 bhn. I can get up to 65 lbs in a $14 flat rate shipping box. The price stated is per 1 pound unit. This alloy is not suitable for black powder bullets.
