I haven't been able to start reloading yet since I need a desk to put the press on, but I was getting impatient to do something, so I decided to tumble all the brass I have been collecting. I had originally been thinking that I didn't need to polish the brass because shiny brass wouldn't matter to me, but when I went to the store today, I realized that I do care if it is shiny. So my brass is looking great now! However, in almost every .45 case, I have a 9mm case stuck inside and it is not easy to pull them out since there is not a lot to grip on to pull them apart. I'll be keeping my .45 and 9mm separate next time.
