Because there is no real differance inside of 250 yards between them in trajectory and in some side by side test the RN's drop less than some pionted bullets. Next is they have better termial performance by design due to there large round nose, scaloped and slited jacket, and the extreme thick mid section. In short they shoot as well or even better out to 250 yards hit harded, expand better and hold together better to punch out the outher side.
If your hunting 250 yards and under ther realy is not a better deer/black bear/elk/moose bullet for the 30-06 just more expensive ones.
The old CLRN bullets are some of the best we can shoot today for 250 yards or less depending on what cartridge it is in.
