No dog in this fight and no offense John Burns, but I'm with Phil Shoemaker on this one.
After reading 20+ pages of this debate I recall the story of the 280 Ross. Back at the turn of the 20th Century, this was a highly touted round at high velocity. The problem was frangible bullets, not saying the Bergers are the same construction but similiar attributes, when used to stop DG charges, people ended up mauled and dead, as did the round.
You may not believe the two relate but there are principles that are the same.
If I hit Lotto and have the coin to hunt Brown Bear in Alaska, I will be booking with Phil and taking his advice bringing ammo loaded with Nosler Partitions or Barnes X Bullets, whichever shoots best in the gun I will be using.
