150 grain core-lokts typically do exit on broadside shots. 150 gr. Win. Power points expand more easily and to a wider mushroom and don't exit as often. Can't say what you'll get with Federal 150's as I've never used them. 170 gr. bullets do usually penetrate more than 150's. I've never recovered a 170 core-lokt or Silvertip except on lengthwise shots, even though I've put them through both shoulders on heavy bodied bucks several times.
