Anybody got any methods that they use to keep track of what reloading their brass is on? Since I'm new to reloading almost all of my brass is currently once fired. Some of the .45 has been fired twice. I've been keeping brass in coffee cans but if I fire more factory loads, I would have to start more cas to keep the brass seperate. Is this something that others worry about or does everybody just lump it all together? I want to be able to keep track of when my brass should be reaching the end of its usable life.
