First off, sorry if I'm in the wrong section. Wasn't exactly sure where this post belonged. Anyway, I've been checking out some of the Lee molds and notice that their designs that were intended for tumble lubing have multiple smaller grooves rather than one or two larger grooves for the lube. So, is it necessary to use this design if you want to use the tumble lubing method or can it be used with pretty much anything. If relegated to those designs intended for tumble lubing it kind of cuts down on the available options. Currently I'm interested in .356 and .401 sizes.
