What Tamara said.

The expansion of a hollow point bullet depends on its velocity when it hits the target: higher velocity = more expansion. The bullet is going fastest right when it leaves the barrel of the gun (which is why people talk about "muzzle velocity" when comparing guns or loads); it slows down after that, so...
