For many years since I purchased my 550b from a friend. I have a\had a brass feeder that I could not use due to ceiling height. I took the press of the "strong mount" today, lowering it by 8 inches so I could use the auto-brass feeder. Should have done this a long time ago. Here are three short videos of a Dillon 550b now with feeder running. 1st is internal shot of the feeder. 2nd is external shot of feeder (note that it has a clutch that I have not yet adjusted, so once it 200 rounds I have to "bump start" it when it binds from weight or a sideways round). 3rd video shows the press in operation completing a round at each pull. Please forgive my incorrect vernacular. I believe I said "de-sizer+ instead of de-primer for the first step. First Youtube video... finally got acceptable cam. I also refereed to stage one as the "de-sizer rather than the de-primer. Please forgive my complete you-tuber greeness! this is a collection of short videos... 1st, brass feeder inside. 2nd, brass feeder external. 3rd, makin" rounds. Sorry vis two is sideways. I WILL figure this stuff out! lol [ame="https://www.youtube.com/watch?v=tXSHZqHlPCU"]https://www.youtube.com/watch?v=tXSHZqHlPCU[/ame] [ame="https://www.youtube.com/watch?v=qiNGqfQcflU"]https://www.youtube.com/watch?v=qiNGqfQcflU[/ame] [ame="https://www.youtube.com/watch?v=7Be8bjFwXC8"]https://www.youtube.com/watch?v=7Be8bjFwXC8[/ame] If you've had/have any question regarding Dillon presses, I hope this displays the answer you wanted. If not, pleas let me know and I would be more than happy to explain or use the opportunity to make another vid. These above are my first ever videos. hope they weren’t too disappointing! ;-) I know they were breif, but my intent was to keep them right to point.
