There is one more benefit as well that hasn't been mentioned, maybe because it is a grey area, but when others know you can make bullets the trade value can be very good in a times of need. In a time of need that grey area becomes more black and white, there will be those with bullets and those without, hopefully it doesn't come to that but.......
I have always said it is a hobby and one is free to spend as much or as little on their hobbies as they wish, there is certainly worse things we could spend our money on.
Good shooting and swage on!
