John,
I have taken many many wildebeest, zebra, and oryx, all of which are considered pretty sturdy. It doesn’t seem to matter if I use a 270 or a Big 7. With good placement they go 25-45 paces and fall over. Hit a little less optimally they might go 65-75 paces. Hit poorly they go miles.
Have been with many hunters shooting the same animals who used 300’s and 338’s and the results are the same with the only difference being that the cartridges with more recoil always cause the shooters’ marksmanship to deteriorate.
This year will be packing a 6.5 wildcat and expect results just like my 270.

PS I think a 6.5 CM with 120 monos would produce great results.
PS #2 I visited with Allen Day and he was a believer in the magnums. He especially liked the 338 and 416 Rem both of which were Echols Legend models. He was a far gone lover of fine rifles. I had one of his for a time and have handled several others. He made some trips to Africa but I don’t think there were that many. He was a really nice fellow.
