My African exploits pale compared to many (most) here, but have done Cape Buffalo and Lion, both .375 H&H. I used two very different bullets, 300gr TSX for Buff and 300gr Interocs, widely viewed as a junk bullet, for Lion. Took numberous plains game with 235gr Speer Hotcors, 270 and 300gr Interlocs, 270 and 300gr TSXs. My favourites at the time were the TSXs but I couldn't ignore more spectacular bang flops with the cheaper bullets, granted these pertain to species lighter than buffalo though many still not small (Zebra, Wildebeest, Gemsbok etc).
Now fast forward to home where I outfit and guide coastal Grizzly / Brown bears, Moose, and Mountain Goats in volumes to form opinions with some leg to stand on. This improved performance from slightly more lightly constructed bullets continued to be evident, however a particular recipe needs to be in place. The results I like occurred with fast loads, and a bullet that violently disrupts tissue, and doesn't exit. Exits are now in my view wasted energy your shoulder enjoyed Newton's law thereof for little reason- below big bovids, elephants, hippos and such. On those that excessive penetration is necessary in my view.
I've just recently been sponsored by CEB (full disclosure), and am considering loading my client loaner rifle with them, and my personal backup .375. I'm feeling pretty good about them academically but will have to wait on a formal opinion until after a couple seasons and testing them on black bear hunts. They seem to have both the tissue disruption I like, and the penetration, a rare combination. The Partition does an admirable job of this mix too it should be noted if moved fast enough, as does the Accubond. The quickest kill I've seen on a big bear was the .300 Ultra with a 180 Accubond, no heavy penetrator, but kills like lightning. I don't think you need that much speed but no denying it works, I like 2,500fps and up for big bears. Only taken one Lion but I liked that recipe there too.
What puts a tense smile on my face admittedly is African dangerous game style loads for big bears- heavy for caliber, stiffly constructed bullets. It's a different mechanism of terminal effect I'm after on them than those loads provide. Did two Grizzly / Browns with 200gr Trophy Bonded Bear Claws from .300 Win in September, impacting the bears around 2,000-2,100fps at the range shot. With good hits they had time to spin and look at the hit, try and figure what was going on whilst two more good hits were made on one and one more on the other, and one ran the five yards back into the river and died, going downstream fast. No load can be counted on to kill like lightning, and both these bears discussed were dead on their feet. But you sure see a more impressive effect, more often, with more speed and a bullet that violently disrupts tissue.
If it does less meat damage, it delivers less shock, and bears are much more susceptible to shock than buffalo. I'm not trying to say the stiffer heavier bullets don't kill, they certainly do! They just aren't as likely to anchor soft dangerous game on their own shadow as something faster and more violently expanding. There are thresholds here, I don't profess varmint bullets, I like properly motivated Partitions, Accubonds, Hotcors, etc. Even the DGX does well and seems its too-soft-for-buffalo construction works alright on bears (.375, top bear pictured). Like I said big hopes the CEB Raptor proves to be perfection after a bunch of testing, no Grizzly / Browns dropped by them yet. I came across them because I was daydreaming my ultimate bear bullet, a mono that fragments petals reliably, and a friend said "You know a company called CEB makes that."
