If the brass is dirty, I keep it in open bins like come with the Dillon presses until full, then I move it to a larger plastic container, like tupperware. The 99 cent store is a great place to find such containers. they are cheap, and you can have everything consistent in size, thus taking up less room, and being a little more tidy.
If it's clean brass, it's not long before it's loaded. then it either goes into 50 cal ammo cans or 50 count plastic boxes.
