Well, especially if it didn't hit ribs or other bones it may well have sailed on through. Ballistic Tips are generally fairly "soft" compared with many other expanding bullets....but they aren't quite varmint bullets....especially in a .338. That bullet was probably designed with deer and other "smallish medium game" in mind, but an 80 pound deer doesn't offer much resistance. I would be kind of surprised to see no bruising....but stranger things have happened.

Though your original description sounds alot like a .357 to .44 Magnum at handgun velocities. (Not a HP but a rather good Soft Point....or even hard cast lead.) But who knows?
