Yeah, Wednesday's episode of The Best Defense (re-run) had Janich and The Pincus demonstrating what common rounds will do to a refrigerator...... Found this interesting:

The door has been taken off so I was shooting straight at the back of the inside of the fridge. It was loaded with CCI Maxi Mag HPs. These are the entrance holes.  Notice that they are clean and perfectly round - no sign of keyholing:

These are the exit holes.  Notice that they are also clean and perfectly round with no sign of keyholing.  However, they did appear to be a bit larger than the entrance holes.  Whether this was due simply to the metal tearing as the bullet exited or deformation/expansion of the bullet I do not know.
