The answer to that problem is to start hoarding them now!

We do!
I guess I am the guy that is doing it the "stupidly expensive" way. I have a few Lee molds. One guy on a casting forum says he is too cheap to buy Lee molds. If I may suggest something it would be this: If you do get Lee molds, steer away from the 1 and 2 hole ones. Also, and this is just me, the tumble lube ones too. They can be hard to get filled our with straight wheel weights without using some additive, namely tin. If you buy the Lee 6 cavity molds for either of the calibers you mentioned, you will want a larger pot than the 10# one or all you will be doing is filling the pot! 6 cavities and greater than 158gr bullets will empty a pot in a hurry!
Don't dawdle. If you are going to get into casting, do it. The best thing about doing is is that you will never be out of bullets and the ones you use will be of the type you personally picked. You won't be at the mercy of any market changes or supply problems. As long as the neighbors have cars, you can have bullets! (Just kidding!
