I took a greater kudu with my Tikka 412 in 12/9,3x74r, using factory Norma Oryx 286 gr at about 80 yards, hit behind the right shoulder and across the front edge of the left shoulder...lodged just under the skin. It had fragmented badly.

I've also used the same loading on deer (2) and found them to perform about like the Speer 270 Hot Cores I had used for a long time. They seem a bit too soft for even the 9,3x74 velocities...for my liking, anyway. Accuracy is superb!
