Two tubes, two motors, one process.
Inspired by an auger (and refined through simulation, testing, and iteration), a large tube with deep spiral grooves pours a large amount of powder in a controlled manner, allowing flow rates up to 50 grains per second, and ramping down smoothly to within 1 grain of the target. A smaller tube then completes the charge within a kernel in roughly the same overall time as V3.

But judging from his post concerning the V4, that V3 orders may be changed for V4 if not shipped yet, I wouldn’t see why not for a V2-to-V3 update
