I really appreciate all of the comments and understand most of the cons.
I got into guns, not for something to do, but for self defense. My wife and I are retired, so money isn't as available as when we were both working. I'm getting into reloading as a means to be able to shoot more. Most of my guns are 9mm, so that is what I will be reloading. The weak spot in my reloading stash is bullets; which I've accumulated 3500, but shooting 500-600 rounds a month isn't going to last that long. So looking at casting would bring the cost way down, from 0.10 to about 0.02 per bullet; which would make shooting a lot more affordable.
