I'm a heavy bullet fan. I use 250 grain Partitions in my 338's. They shoot so well, I have not tried much else. I have a 7 point bull elk's antlers in my gun room. That bull was shot lengthwise with those 250 grain Partitions, no second shot was needed. I've read where other bullets work as well. But I do not know that from experience.
The Speer bullets in other calibers always hold together well for me. If I had access to 275 grain Speer bullets, I'm confident that they would do well for anything on this half the world. I'd bet they would work well on Cape Buffalo, but I wouldn't give odds.
I'd like to see how those 275's perform in a stack of tightly bound dry newspaper.
