Does pure lead cast larger diameter than a 50/50 mix

[Pipefitter]

Short answer: yes.
also needs to be "worked" at a higher temperature than alloy lead

will you be running your cast bullets through a sizing die?

50/50 of what?

[Taylor]

Pure lead and coww

No, not if I can help it.

softer, cast = smaller , harder = larger
hotter = smaller (more shrinkage) cast cooler= larger

the purer the lead the more it shrinks

taylor alloy and casting temperature to get the finnised diameter you want

[Taylor]

Thanks, I 'll keep that chart. I haven't cast pure yet.

Pure shrinks the most. The higher the antimony/tin the less it shrinks on cooling. That's why type metals have such a high antimony/tin content. And to reduce deformation from use.
