It depends on the gun for me. But, a quick run down of what they are: 240gr XTP; 300gr WFNGC cast; and 260gr Power Coated Keith Bullet. I?ve killed more whitetails with the 240gr XTP than any other bullets I ever used - they?re just so accurate out of most any gun you use. Don?t know the total of kills over the years, but it?s been a few and I?ve only retrieved one XTP bullet and that was on a big Illinois deer shot at 60 yards through both shoulders - it was under hide on off side. I know the XTP can ruffle some feathers in discussion, but for whitetail, they?re basically my go to bullet. I have some of the 270gr Speer deep curls loaded for my FA and they shoot great, but I have yet put one through a deer. I?m looking forward to some critter testing in the future and think it has the potential to be the best all-around jacketed bullet for whitetail - time will tell.
