Nick, all the lead-based wheel weights I'm familiar with are lead & a bit of antimony, no tin involved. You can find 95/5 tin-antimony solder, though, and add a bit. Last I looked, a couple of years ago, it was about $15 US for a pound of the stuff. You can also order pure tin, but I've no idea what it costs any more.
As for making the bullet molds, my understanding is that they are made by squeezing a pair of blank mold blocks down on a rotating "cherry" (bullet-shaped cutting burr) while holding them in alignment with one another. IIRC, that is described in James V. Howe's The Modern Gunsmith. In the PDF of the 1941 edition I have, the description starts on page 307 of volume 2. I'd have to dig out dead-tree copy to see if it's elsewhere in that edition.
HTH!
