To me in plinking loads it doesn't matter anymore. There was a time when I would sort it out but I've picked up so much over the years I just lump it all together any more. Different brands in brass and nickel, large primer, small primer, large flash hole, small flash hole. Took too many bins. Now if I shoot any of it at least I know how many times it's been shot by me and none of it gets left out. It's especially useful if I'm going to a range where I'm not guaranteed to find or get it all back. There's nothing worse than shooting new brass only to have it land beyond the shooting line and you can't retrieve it.

Sorting "my" brass however is a different story.
