I just watched an episode of "extreme outer limits" where they said that the Berger bullets are designed to penetrate a few inches then dump all their energy in the animals core (fragment). This sounds to me like what the ballistic tip bullets do when you push them too fast, either causing immediate devastating results or failing. Does anyone have any experience with them? In particular on tough shots like the classic follow up Texas heart shot. Do they get enough penetration in these less than ideal situations to get the job done? Also how are they for cape damage, when pushed too fast the ballistic tips tend to make a huge entrance and no exit, are the Bergers similar?
