When bears charge you it's very fast and you are presented with shot angles which are less than ideal. The bear is very motivated to get you. What's called for is an expanding bullet of decent caliber that digs very deep.
I've never used any Berger or ballistic tip and likely never will simply due to my interests. I don't have any inclination to shoot big game animals 7 or 8 hundred yards away. What I like is hunting deer where brown bears live and therefore what matters to me ( and frankly should matter to anyone who hunts in brown/grizzly bear country) is how will my bullet perform on a bear at ten yards just as much if not more as how it does on a deer at 300.
