Bion, I still have and use METAL one-pound coffee cans for the great majority! My casting criteria, too, is generally to over-fill a can -- and then after pulling culls, sizing, and lubing -- turns out to be ~ an inch below top. Interestingly, I stopped keeping lids snapped on, as (to me?) it seems bullets seem slimy and stick together a bit if lidded. Might be just my perception, only, but, again, I keep them in the cans -- un-lidded.
Years back, MidwayUSA used to sell actual blue plastic square boxes for bullet storage and I bought/have a couple of dozen of these as well -- and use these for either odd-ball creations or bullets I do not shoot that much of -- but want on hand should I get the urge to load and shoot some.
