An old treadmill would be an excellent starting point.
I do think you are going to need paddles or else the contents will sit still while the drum rotates around. Just speculation, tho - try it and see.
Quantity, I'm not sure... up until now, I ran out of hp before I ran out of room. I would guess at least three hundred 223 cases. In my setup now, I think I could use more pins - only have 5lbs now.
RPMs; I intend to experiment with this as the A-B drive allows a 10K ohm potentiometer to vary the speed from zero to way-to-fast.
