Just for what it's worth. I was thinking about easy ways, other than weighing, to reliably get 1 pound of dry pinto beans from a five gallon bucket. The beans would not be in 1lb. packages but loose. A scoop would be inconsistent so some sort of container seemed appropriate. Looking on my shelves I saw 1lb. bags of beans next to Classico jars. Hmm, looks good.
I poured one sack into an empty Classico jar and that filled it to the ring under the threads. I don't think you would necessarily need a scoop but it might be easier to fill the jar with one. The graduations on the jar might make it easy so approximate other weights of beans.
