The purer (softer) the lead, the more the expansion on impact. If I'm using a sabot, I like a little harder bullet than pure lead for penetration.
I'm not up on Brinell Hardness Numbers and how they translate to too soft or too hard. When casting these bullets, I toss one recovered SWC from a centerfire reload in the Lee pot with the pure melted lead and stir. It makes the bullets just a bit harder and also seems to make the castings crisp without rounded edges .. probably due to the tin in the commercial bullet. Tin isn't supposed to make the bullets harder but the antimony does.
