I just toss'em in the scrap brass, but then again, I'm not sitting on hundreds of them either. If I did, I'd probably toss'em anyways though, I'm just not one to spend much time on things that hassle me. If buying mixed brass, I do look to see if they specify sorting and if not, I will ask before buying. It seems to be more of a problem here in the last few months as I have heard other guys with problems also.
G-N - $1.70/# is pretty decent for scrap, got enough for a beer or two!
