Yeah, if you don’t have the AP ammo and your target isn’t wearing armor, what you have is a very expensive and not very effective .22 Magnum pistol.

These ballistics tests showed 4” wound channel in a pork shoulder. Ballistic gel was showing 9 to 11 inches of penetration. Its hardly a .22 magnum. Obviously it is not in the same league with a .223, but it does leave a really nasty wound channel. It would be interesting to know the extent of the police officers wounds.
