Thanks to Surrogate for the design of the Brass Case Sorter, a set of 3 brass case separators. Sorting out 380 cases was still an issue. I found that range pick-up brass had the following diameters - 9mm = 0.390" to 0.394", and 380 = 0.378". I modified Surrogate's 9mm separator to have slots that are 0.383" wide, to catch 9mm brass on the top side and let 380 brass fall through. Depending on how your printer prints, you will likely need to do some light filing to touch up the slots to let 380 brass fall through. Be careful, as it is easy to file a bit too much and then the 9mm brass will fall through too. This will work ONLY for brass that has not yet been re-sized.
