I have had absolutely no problems with Ballistic Tip bullet in a variety of chamberings and bullet weight to harvest upto deer sized game. In fact it is my favorite deer bullet. IMHO if your a rib shooter this bullet will not give you any worries! My experience mirrors that of other BT users...dead deer with very few yards travelled after the shot. I have made a couple of poor shots in my career with this bulletbut not one has led to a lost animal..thesewere notbullet failure but rather shooter failures!

I have said this anumber of times here and elsewhere, do your research pick the bullet that works for your situation (consider distance of shot, placement, game, construction or design, etc.). If you do this then you'll find more success in the field. Personally wouldn't consider the corelokt to be of any benefit over the NBT, I would also consider it a rib shooter bullet. If your a hunter who likes to break em down then go with a controlled expansion bullet such as the Nosler Partition, Speers Grand Slam orAccubond (or similar bonded polymer tipped bullets)...these are pretty much the best of both worlds, designed to open up but yet still retain weight for heavy sluggin' or penetration.
