I've had problems getting a hold of wheel weight too. Patience, and car dealerships have worked out. Their service depts do balancing. I have a connect now, but it took some reaching out.

The ebay route is ok for alloy sometimes, but most think they are selling gold. It is worth it to cast some bullets. I think you'll be pleasantly surprised at what you can do when you start making your own alloys, casting your own bullets, and getting superb results. As I said, it was easier than I thought it would be. I did and do a lot of research. You can find a lot of good stuff, and answers to many questions, here:

In fact, the LA shooting club has a lot of great stuff on their site.
