Dillon CM-500 Separator Dillon CM-500 Case Separator. After Dillon sold thousands of their famous first-generation FL-2000 case cleaners, customers who had purchased them began asking Dillon to address the problem of separating the cleaned and polished brass from the cleaning media. Dillon knew from the beginning that the simplest method of separating would be a rotating cage, but they had to find a design they could manufacture economically. The solution was an injection molded reversible part. It's simple, and it works great. The CM-500 case/media separator is designed to handle the load of a CV-750 case cleaner which is about 500 pieces of 45ACP or 38/357, or about 200 pieces of 30-06 brass. The tub measures 13.5' x19.5". This is the smaller of the two separators in the image.
