I have shot 3 cape Buffalo.
First a cow at 12 yards with a 480 Woodleigh Soft, from my
NE 450 No2.
Perfect broadside heart shot. She went about 150 yards in thick jess. When we walked up on her she tried to get up, 2 480 Woodleigh solids ended the deal.

Second a buff bull, shot running at @ 30 yards, hit with a 500 gr Swift A Frame also from my 450 No2.
He ran out of sight exactly when I shot, shot hit about mid body ranged up through heart stopped against off side shoulder.
He ran about 50 yards and was down. As he scrabbled around I hit him with 2 480gr woodleigh solids. As I approached he tried to get up and come for us. I hit him with another Solid entering the right neck ranging through the spine into the body. This shot knocked him down on his right side. Another 500 gr Swift A Frame through the front chest into the heart ended the deal.
I have a picture with me holding the heart with the 2 bullet holes in it.

Third buff, a very large bull. Much larger in body and horn that my other buff. One shot from @ 60 yards with my 9,3x74R, 286 gr Woodleigh Soft. He was facing me at last light. If I had not had a scope with an illuminated reticle I doubt I could have made the shot, he was a black buff in thick jess at last light. At the shot he truned and ran. He was down and dead in about 40 yards.

All bullets were recovered. ALL SOFT POINTS EXPANDED PERFECTLY. THE 9,3 GAVE AS MUCH PENETRATION AS THE 450'S.

While I have no doubt the 450 is better as a stopper, the 9,3x74R is a great killer.

I shot an elephant cow and a giraffe with the 9,3.
I also shot a giraffe with my 450 No2. It took 8 shots, all in the right place to knock him down, I shot another giraffe with my 9,3. 2 shots and he was down!!!

I would not hesitate to take my 9,3x74R Chapuis to Africa and hunt all of the Big 5 with it.

PS it is great on Plains Game too.
