[QUOTE="Max Heat, post: 653362, member: 43153"] My auto-disk (pro) setup already allows for stacking of the disks without any sort of "conversion" required. But even if there WAS a problem with powder measurement, there is always the "adjustable powder charge bar" option for the auto-disk setup (it's only 10 bills), if I were to need it. I'm sure it's been designed to be compatible with the disks, in terms of stackability. This would allow for a pretty much infinite # of different (and very precise) charges to be measured out. The issue I currently seem to be having involves the dropping of the charge into the cases, after it has been measured. And since the powder I will be using is of the stick variety, I would REALLY like to have the proper die, along with the integral (but separate piece) drop-tube that goes with/inside of the die, to minimize the possibility of any powder getting hung up, and ending up being added to what is already going into the NEXT case. Obviously, the top of the die needs to be threaded on the inside to match the bottom (outside) threads of the thumbwheel on the auto-disk powder measure. I suppose that a die that does NOT use a separate drop-tube inside of it would still work, if that's the only kind that IS available for the 7RUM cartridge.
