On my one and only hunt so far in Africa, my brother and I borrowed our PH's Sako 30-06 loaded with Barnes TSX 165 gr. bullets at about 2800fps. Every one of the 16 animals we shot well died quickly. The Eland I shot badly at about 300 yards needed several more shots. The Mountain Reedbuck that my brother shot too far back needed a finisher. All the others, including another Eland, a Zebra, a Wildebeest, 2 Kudu and and Oryx were quick one shot kills.
It's the only bullet that particular PH uses any more. He really has faith in them.
But I'd be just as happy with 180 grain N. Partitions, A frames, or several other good bullets.
