You guy who have been using the rotary tumblers and stainless pins are absolutely correct on how well they work. I picked up a used Lortone Model R Rotary Tumbler from flea Bay last week. I ran the first batch through it today. They were filthy range pickups. Dumped in approximately 750 223's, stainless pins, some dish soap and Lemi Shine. Had to make a delivery so they were in approximately 3 hours. Opened it up at 5pm this afternoon. OMG! They are shiny bright and clean and no dust to breath in while separating brass from the media. Wow, I see no need to use the two Lyman dust bowls again!
