Pure lead brinell hardness
WebJan 21, 2010 · 92% Lead. 6% Antimony. 2% Tin. Saeco Hardness 8.5 to 9. Brinell Hardness 16. He calls these hard cast bullets, I've read the article from Shakey Pete's Shootin Shack concerning cast bullets. His article say's that most commercial suppliers use a 85% lead, 5% tin & 10% antimony and that they're to hard to slug up properly in anything other than ... WebRelative hardness of the bullet is read off a vernier scale. The vernier scale is calibrated in arbitrary units from 0 for pure lead up to a SAECO hardness of 10. We have found that a SAECO hardness of at least 6 is required for medium velocities in handguns and a SAECO hardness of over 8 for Magnum handgun and gas check rifle bullets.
