I did a bit of research about this awhile back. Let's start at the ONLY sensible place!

Click on the element symbol, and you go to the Wiki page about that element.
Soon enough, you find that we have an estimated 30 years remaining of lead. That doesn't include further mining.
We find that Bismuth is a by product of lead refining, so it's a bit of a moot pursuit.
Cadmium and Zinc have toxicity issues, and they're very light.
Copper is the obvious choice. It has to be machined to make bullets, so it's a bit more expensive that way. Behind Iron, it's the most abundant metal on earth. As long as there is earth, there is copper.
