I usually start with a round India stone and establish uniformity of the ramp and remove tool marks by hand. This is just because it's easier to make a straight ramp without ripples in it that way. Once the stoning has got the shape I want, then the Dremel tool can be used with finer abrasives or with your buffing compound and a felt bob. Be sure that the bottom edge of the barrel doesn't overhang the feed ramp in counterbattery when you are done.
