When I first started reloading many years ago, I bought and used the plastic boxes to put my reloads in. They sure looked purty sitting on my shelves! But, after arriving at the loads I liked, I just started putting the reloads into 30cal ammo cans in bulk. When I go out to shoot, I grab the ammo cans and go. When they start to feel light, I know it's time to fill them up again. I still use the plastic boxes whenever I just want to run out and pop off a few, just fill them out of the can and go.
