My northern transvaal guides all preferred a 100 yard sight in. They said the biggest problem they had with American hunters was high shots usually at around 150 yards or so. One even suggested I resist in but I assured him I knew my hold unders as well as overs.
If I went for a cat with a 308 I'd probably use a 150 partition at around 2900 fps. I usually shoot the 155 scenar but have had reports that it can be a bit hard. I've always liked the way the partition comes unglued a bit in the front quickly but still pushes deep.
