One of the present 8-pound jugs from Alliant will screw things up considerably, since they're twice the size of a Hodgdon or Ramshot jug. In fact, they'd probably hold 20 pounds of most powders.
I use plastic coolers. The common Coleman 48-quart cooler, available in lot of places for 30-some bucks, will hold six Hodgdon or Ramshot 8-pounders neatly, and you don't have to build it.
