All of those will work but I would be happiest with someone using any of the Noslers.
I come from a long line of Alaskans and Montanans. The Alaskan side of the family have killed a lot of bears. They've always used Nosler Partition bullets. The 300 grain Partition in the .375 H&H being a favorite.
I've only taken one inland grizzly and it too fell to a Nosler Partition, but not from a .375. My father has taken a couple coastal bears now with a .338 Federal and 210 grain Partitions.
