For me, there are two different types of ammo I buy: (1) Cheap, Plinking, Target Practice Ammo and (2) Expensive, Self-Defense Ammo.
I don't have much of a problem buying expense self-defense ammo because I don't really shoot much of it.
But, I do have a need to shoot lots of target ammo. Ammoman.com seems to have decent prices, but I have never used them.
Usually, I buy my ammo (.45 ACP) at Walmart, cause the Winchester White Boxes seem to be the cheapest around, off the shelf and out the door. Anyone know where you can find .45 ACP FMJ target ammo cheaper than at Walmart?
