Have a friend that used big round bales of hay stood on end to line a old quonset shed (had concrete floor) then he filled with beans up a few feet on the bales. Said it worked great and would do it again. He has a big Fiat/Allis articulated loader he uses in his hay business that he loaded them out with into his semi. Took about half to two thirds bucket fulls and didn't spill many beans at all.
