I am tired of beating this dead horse, but since the general consensus is that Berger bullets are insignificantly constructed and can't be depended on at high impact speed or when interacting with bone, I wanted to post a bit of the thread I referred to earlier in this thread. The results seem at odds with the consensus.

After all the discussion here denigrating Bergers, it doesn't surprise me that many think them inadequate for a defensive situation against a bear. And if UncleJesse is not confident in them, then I would agree that they are a poor choice for him.

Cow bones for testing
