What are the advantages of these add-ons? I see them in four- and six-inch versions in Sinclairs, and have seen some here mention them in regard to better consistency in powder throws, but what do they really do and how do they do it?
If you have a full/over full case load, that all the powder will not go into the case, you need a 6 inch drop tube. You can fill the case, for some reason, with a long drop tube, but not with a 1 or 2 inch funnel.
