Casting can be as cheap or as expensive as you allow. Accurate molds, Miha, NOE, or Lee. Let your wallet decide. Sizing...same..Star, Lyman RCBS or Lee. It doesn't take long to get a few thousand $ tied up into casting if you let it. I cast for everything I shoot, 22cal to 45/70 so I have a lot tied up just in the casting aspect but it's a great learning experience.
