I just bought an ammo case to hold some 22LR bullets, and noticed that the CCI mini-mag boxes fit perfectly in there. While I plan on buying more over time for the same purpose (and the bullets, of course), I would love to get ahold of some of these empty. Are these sold anywhere? I'm partial to the 100s, but 50 count would probably work alright. Obviously cost is a factor, as unless the cases cost significantly less than the CCI bullets, I may as well just go buy more ammunition, and refill as I get empties.
