I have one, but I use it on a Lee Turret press. If you used their Powder-Through Expanding die it would almost certainly work. The measure screws directly into the top of the die, and is actuated when you run the case into the die. There really is no "drop tube" per-se, but you do need the powder/expander die for each caliber.
I like mine a lot. It's very accurate, within .2gr with W231, for instance. Because of the way the measure operates it may not be quite as accurate with stick powders, and it doesn't seem to like the little Trail Boss donuts very much, but other than that it's been great. I hand measure most of my stick powder rifle rounds anyway.
One thing: Since it's a disk operated device, you get what you get as far as measurements. For instance, one disk cavity might drop 6.5gr of of a particular powder, and the next cavity up might drop 7.2gr. If you want something in the middle you're kinda stuck. They have an adjustable cavity "disk", as well as a double disk kit if you need more powder than will fit in any single cavity. When I loaded up some real hot .44 mags with 31gr of H110 I needed to use two lever pulls at the powder station.
Once the thing is set up it rarely varies more than .1 to .2gr. Checking thrown charges becomes simply a cursory exercise. I love it for cranking out ammo.
