There are those who feel that the next power level above a .30-‘06 / 180 or / 200 is not encountered until the .375 H&H.
For me that increment comes at 338 Win Mag power level.
The Wby RPM is going to offer slightly less velocity than the Win Mag, especially in the higher weights;
but as a plus 4 or 5 down.
Tough to carve a niche when you’re competing with the .30-‘06.
