Cast with 6Sb2Sn92Pb Antimonial Lead equivalent with Lyman #2 Casting Alloy (Commonly known as Hardball or Magnum alloy).
What does that mean? 92% lead, 6% antimony and 2% tin an 18 BHN hardness scale .
It's simple -- 20+ years of competitive shooting, reloading and casting. I know what I like and hopefully you will too.
