Howdy,
Some of these older threads are the best sometimes.
My one kudu scalp gives me no right to proclaim what is a proper kudu rifle.
Nonetheless the story is possibly worth mentioning.
The only kudu I have shot was with the .300 H&H and 180 Nosler Partition.
He was quartering toward me at a lazed 240 meters, down hill.
I hit him spot on the shoulder, braking it, tearing through the boiler room and braking an off-side rib on the off side.
Exit hole about the size of an oblong golf ball.
The impact seemed to knock him off his hooves but as the PH was congratulating me, the animal leaped up and ran on three legs like a scalded cat, right to left.
I fired two more shots, now about 300 and 350 meters respectively.
One hit a stick, according to the PH, at any rate it was a clean miss.
One notched his hump like an evil child had taken a bite out of him.
He went down hard, in a cloud of Namibian dust, before I could make a 4th shot, and he stayed there.
My first shot had killed him but he jumped up and ran a ways in spite of his death.
I would not mind using the .300 H&H again for kudu but, I believe the 9.3x62 would be more to my liking (I since have had one built on a '98 Mauser action.)
By my wacky way of thinking, the .243 is not a kudu rifle.
Here in Alaska, it is one of best wolf and coyote rifles money can buy.
Cheers,
Velo Dog.
