I have seen maybe 50 or more buffalo shot and killed by Saeed Al Mactourn, the boss hoss at AR, with his 375/404 loaded to the same velocity as the 375 Wby and with 180 gr. Barnes and his only monoliths..It killed the buffalo as well as any caliber I have seen or used, and thats a bunch of calibers...so yes its a great option with proper bullets.
Ray :
you mean 270 grain right?
He uses 300 grainers of his own make, which are Barnes TSX style.
Over recent years he has tried a few velocity levels and all with either 300 grain Barnes X or his own bullet. He used over 3100 in the 375 Lazzeroni (like 378 Wby or 416 Rigby Improved necked to 375) and 2850-2900 which was more or less top loads for his 375/404 Improved, 2600 plus which would be real top end H&H velocities with that long bullet. However, for his last few trips he has settle on 2750 which as Ray says is like top loads in the 375 Wby.
And he shoots every type of animal with that pair of rifles. It must be about the world's best endorsement for using a 375 Ultra with backed off loads (or a 378 with even more backed off loads) or a 375 Wby with top loads
