Aluminum cases are used for some ammo (Blazer pistol cartridges, for example). It's usually cheaper, because aluminum is cheaper than brass. The main drawback--as I understand it--is that it can't be reloaded like brass can.
But since rimfire ammo can't be reloaded anyway, why don't they use aluminum cases?
I imagine there's a good reason, but I've never heard it explained.
