I also reload for most of my shooting needs. i have started casting my own buckshot and been considering buying bullet molds for my handgun caliber needs. I think I will go ahead and order the molds in the morning.
Even if prices and availability of components don't soar, you won't regret casting. I've been doing it for years and make more suitable bullets for what I do, at almost no cost. Work out a deal with whoever you get tires from to save their wheel weights. I buy them from the scrap yards in 55 gallon barrels.
Also, learn to tell the zinc ones from lead alloy. There is a push by the EPA to replace all lead weights with Zinc so hording now is a good idea.
