I don't know any reason the 300 gr partition would not work just as well on a 1600 # Cape buffalo as they do on 1600# brown bears.
they work as well as any bullet on big bruins !
Phil,
Brad Dennison had a different view. That's all.
I would be interested in hearing Brad's experiences and reasoning as I have killed a lot of bears with Nosler partitions and seen a hell of a lot more killed with them and never seen any problem with them. They work as well and consistently as any bullet I have ever used, and a few years ago Nosler moved the partition forward on the .375 bullets for even more weight retention and penetration.
On the other hand I have also seen a lot of hunters who were using partitions who badly misplaced their shots but claimed they had made perfect hits and blamed the bullet.
