I found this great site about casting bullets!

It is a very large forum, and is very in depth for folks who reload. What I found interesting is it has all different topics on casting various metals other than lead. I found this site after doing research on casting bullets (and cannon balls) on my own using metals and alloys such as zinc, tin, bismuth, silver, etc.......There is a bunch of valuable information here for anyone with the same interests.
