I've had 2 180 gr Accubonds come apart when shot from my 300 WSM. With one, I found the jacket against the far side of the chest cavity. I later found the core in the heart. It totally demolished the near shoulder, ruining 10lb or more of meat. I'll use about any bullet before I'll use another AB. I've had good luck with PT's, as has anyone else who's used them, but I can't say that they're much better than the Speer Hotcore which has been my go-to bullet for 30 years.
