So I am going to do some bullet casting and I am wondering what needs to be added to wheel weights to make them better for bullets. I will be using it in my .45acp, .454 Casull and a .500 S&W. I am pretty sure that for the .45 ACP it would be fine as is due to the low velocity but the larger faster stuff might need to be a little harder. I would consider some rifle calibers as well once I figure it all out with the slower pistols.
