A guy at the range was telling me that the best way to get brass clean is to use small steel shot (#7 or #8), hot water, and something like Dawn dishwashing liquid in a tumbler. He decaps first, and claims that the BBs get everything superclean, including the primer pockets. Since the BBs are obviously reusable, this sounds like it might be a pretty cheap way to get brass clean. Anyone tried it?
