I noticed that new, shiny brass makes it really easy to see the powder drop on a Lee Pro 1000 press. Mostly it’s not a problem with 9mm or .45acp, but seeing down into .38sp and .357 magnum case is. I noticed that shiny new brass, just bought, makes it real easy. If the press were to drop a smaller than expected load then I can pick this up by sight. But it’s much harder with older brass that has carbon staining. Would an ultra sonic cleaner leave the brass like new? I don’t want to go the steel pins route.
