I've successfully used Norma Oryx factory loads in several hunting rifles.
.243 100 gr. for Mule Deer, .30-06 180 gr. for two elk and a big black bear, and In 9.3x62 / 285 gr. for Kudu, Oryx, and Giraffe, and in 9.3x74R / 285 gr. for two black bears. Every time and in every rifle, the ammunition was accurate, met velocity specs, expanded very well, didn't mash too much meat, and the bullets I recovered retained almost 90% of their original weight while expanding more than 2 x diameter.
That pretty much defines "perfect" for me.
