I have been seriously considering the Super 1050 to load volumes of 9x19mm (combined with a Mr Bulletfeeder and an P-W Autodrive), but this thread has given led to slight concerns; do you have to sort your brass by manufacturer, particularly for the swage and priming operations to function smoothly? Or are you able to simply load mixed brass into the case feeder and have the Super 1050 function smoothly and reliably?
