I got the Excel spreadsheet that Carlos mentions (and thanks again Carlos for sending to me). It works great, there is a built-in macro so you can do "what ifs" on component pricing to see what your cost is per round, per 50, etc. One thing it showed me was that I'm not saving much versus WalMart. My needs were to reload and send rounds down range, nothing fancy with the loadings and just save money. However now I'm not saving much at all and then with the time committment it makes even less sense. However buying a box, shooting up and leaving the brass would be almost incomprehensible (paradigm shifts are always difficult for me).
