.22 ammo: Is this "the New Normal?"

[Stevensje]

Anyone who hasn't purchased ammo way before this is SOL. There's some deals on 223, buying in bulk. What i don't understand is.........
Who Buys 2-3 boxes and calls that bulk?

What do you think is a reasonably bulk stock on each following? 22mag, 22.,223,308,9mm,45,12ga,357
