HMMM. Spent about an hour talking to Ross Seyfried about shooting a cape buffalo with a handgun, and, I ended up with the sister guns to Ross's, and, it was supposed to have been owned by Ross, but, that was just a bit of a lie by Linebaugh to get me to go for the gun.
25th gun Linebaugh built.
For what it's worth, Ross Seyfried was World Pistol Champ right around that time, and, he put 5 shots of 350 grain 45 Colt at 1550 fps, 27.5 grains of H110, into that cape buffalo, and, it died near nose to nose. He was trapped under some huge thorn bushes, and, couldn't get to his rifle. He got those 5 shots off in under 2 seconds, about the time it takes a cape buffalo to charge from 25 yards.
That said, some friends of mine are going this year, and, they could bring anything they want. Last I heard, they had settled on double rifles, in 9.3 x 74R. This is the rimmed equal to the 9.3 x 62. With a 286 grain bullet, around 2400 fps, it will kill elephant to dukier. Guns for these calibers feel like 22 lrs to me, at least compared to my 375 H&H. If I had to carry a gun all day, I'll take the 6 pound double, or light 9.3 X 62 over the 10 pound 375 H&H.
Here's a world famous gunsmith hitting a jug with the Merkel:

If it was me, I'd take the 9.3 x 62, in a cheaper bolt gun, so when it gets stolen at the airport in South Africa, I'm not out the cost of a new car.
For perspective, here's my 375 CZ 550. It's huge, in comparision and weight, and, for an action that big, it really should have a cartridge like the 458 Lott, 475 Ackley, or something along that line...
