The auto disk is working well for me. I also use the adjustable charge bar. At first I had consistency problems with the small charges, not to mention 2 squibs (my fault because I wasn't looking into every case). I attached a vibrator to the powder hopper which helped immensely, even with Unique. More recently, I found the discussion on loadmastervideos.com about the design flaw of the adjustable charge bar, tried the recommended fix and no longer need/use the vibrator. I haven't retried it with Unique though. BTW, I'm using an upgraded auto disk, not the pro version.
