I have killed many a deer with 165 gn Nosler Ballistic Tips and IMR 4064 from the 1980's to the present. They are super accurate. They ruin a lot of meat if a bone is hit at high velocity though. You will have a fist sized exit hole/channel. Hit one in the neck and the only thing holding the head on is some hide. I always heard that different caliber Ballistic Tips are constructed a bit different, i.e. a 224 will be much more lightly constructed than a 30 or 338 cal. I use to load 180 gn 8mm ballistic tips with a hefty charge of IMR 4064 for my 8x57 muasers. Like any bullet, it works best at a given velocity spread.
