Found these polypropylene test tube/beaker racks for drying brass after running them through the stainless tumbling media. Each has a hole drilled directly in the center, and all I have to do is put them in with the necks down and set them over an air vent overnight. Each rack holds 96 pieces and works extremely well with .308 cases. Might need the other rack for .338LM and larger.
