As far as the Terminator is concerned: I'd be willing to see how well a Cyberdyne Systems 2nd gen endoskeleton held up to a few well placed M82A1 rounds. And how different would that movie have been if the first Sarah Connor, upon being attacked by a strange, brooding, muscular stranger, emptied a couple of barrels of 12 ga 00B to it's face? If I remember the movie correctly, it was pulling birdshot out of it's face. Heck, even a CQB shotgun blast to the face with birdshot would have--at the very least!--had the Terminator looking significantly different as he wandered around town, looking for the actual Sarah Connor. No? Try this: Put a New York Steak on the back of a cast iron skillet. Now shoot it, up close, with a 12 ga. OOB, #7 or #8--your choice.
