Is it OK to leave the powder in the press funnel or do you dump it back in the original container as soon as you are done loading? I only have one type of powder in the house, so mixing powders isnt an issue. Secondly, and this seems like a dumb question, but how do you empty the unused powder from the dillon 550? Do you loosen the two allen-head screws and lift out the whole assembly (minus the die), or does the funnel itself come out separately? Wanna kill these ads? We can help!
