I remembered that I also shot a guinea fowl and a giraffe with the 9,3x74R.
I use 286gr Nosler Partitions, 286gr Woodleigh Softs, and 286 gr Woodleigh Solids. Much better bullets than most factory 9,3 loads.

The cape buff was shot facing me at @60 yards, frontal chest with a 286 Woodleigh Soft. He was down and dead in less than 40 yards. He is the only cape buff that I have killed with one shot.

I have taken seven elephants, four at 6 yards or under.
Only one with the 9,3.

I have also used a 450 No2 and a 450/400 double in Africa.
No doubt they are superior for big dangerous game.

However, actually the 9,3 has proven to be every bit as effective as the larger bores.

Personally I would prefer the 9,3x74R double to ANY bolt gun in a charge situation.
