I have developed a fine collection of large-screwtop clear transparent plastic containers for use in my hobby (affliction), to the point where storing the un-deployed units is becoming an issue. I
do have a very large basement, though.
If I maintained a large & varied supply of primed brass, I think that they would be an excellent storage solution.
The heavier-grade jugs (like Costco Cashews jugs) are
perfect for housing my bulk-purchase component bullets. I currently have ~20 of those on the lower shelf of my reloading bench (along with the 50 USGI ammo cans housing loaded ammo). The big-ass (technical term) "Cheese Puff"-type jugs are handy for storing chargers/stripper-clips, enblocs, disintegrating links, bandoleers, etc.
