The truth of the matter is that there have been several versions of the ballistic tip over the years.The first ones were very soft but they were toughened up over the years to where according to several bullet tests including the latest by shooting times they penetrate and retain weight as well as the hornady interlocks.Most people remember the results of the early versions but do not realize the current versions are very much a different bullet as far as their performance.Some of the earlier versions are still being used so even recent incidents may not involve the newer bullets.I have used the latest versions on elk and moose and they have not failed.
