Not much to say that hasn't already been said by the fine folks above but I will add that if you can source lead casting can be very rewarding. I use bmostly lee products which have treated me well, I have casted and shot thousands of pistols bullets with great success, I have yet to shoot some of my cast rifle bullets though, other things keep taking my time.

If you were to venture into casting a bottom pour pot is highly suggested if you didnt already know that.
Good luck in your venture, let us know how it turns out.
