For practice rounds and range use in .380, 9mm., and .45 ACP I pretty much go with whatever is the least expensive (or else I found it on sale), and stock up on it. Winchester, Federal, Fiocchi, CCI Blazer Brass, and Remington all make fairly decent ammo for this purpose. For concealed carry or home defense I like Speer Gold Dot, Hornady Critical Defense, Federal Premium, and Winchester PDX1 Defender. The only two ammo brands that I really have a preference for are Wolf Match Target and CCI MiniMags in .22LR.
