Never an issue with Accubond's here, they are one of the best all around bullets out there.
I have seen them used on bears, big and small, deer, caribou, moose, and bison. I have never seen an exit wound. That would include four broadside 300gr from a 375H&H in a very large brown bear. I have seen a whole bunch of 270gr X bullets in brown bears without catching a single bullet. And many of the Xs were full length.
