J Morris,
I tried that once and maybe I didn't raise it high enough. I'll call Hornady and see if they have something that works better than what I tried.
If they don't I should start experimenting with it. It isn't doing me any good leaning against the wall on my loading bench.
I'm curious about the OP's device. I can't imagine my case loader with 9mm filling the tube any faster than mine does. My case loader runs once for every case loaded, once the tube is filled up and I maybe get one upside down case in every 1000 or more rounds. I haven't seen an upside down 9mm case out of my case feeder for so long I forgot about watching for them.
