. In my opinion there is no way the bear should not have dropped on the first shot.
That is just an unrealistic expectation for any bullet. Unless you spine an animal they will rarely drop on the spot. With a good double lung shot most any big game animal will travel 50-100 yards.
I myself prefer the Nosler Partition bullet. You get the best of two worlds. Nice penetration and good expansion. I think the old partition design is the best.
