I've got the UCD and the PPM, with an eye to using it on my updated turret at some point for charging rifle cartridges. But, I haven't done it yet--still a learner, and still using the "typical" .223 turret setup with the Pro Auto disk.
FWIW, I do have an older, aftermarket adjustable charge bar that will dispense just what I want in H-335--but that's as far as I've gotten.
I hope you'll explore further and do a writeup--I plan to expand my rifle loading this winter, but not yet.
