Having some extra brass around lets you experiment a little. 30-30 and 303 British are very handy to use. You can make 44-40 and 444 cases from 303 B. That 444 case can be run in a 44-40 size die trim die and made into a 44-40 shotshell, or the 444 case can become shotshells for your Judge/Governor. 30-30 brass will do the same in 41 mag.

There aren't many pistol rounds you can make from 45-70, but they are still cool to have around. I'll have to make some salt and pepper shakers that won't poison me! Brass for pepper and nickel for salt!
