I won't get into a debate of one cartridge over another, discussions of this nature will go on till the end of time. As for the 325WSM, Winchester has done this before. They throw a handful of new cartridges at American hunters all at once, some of them stick some go away. They did it in the 60s with the 300, 264, 338 and 458 Win Mags, the 300 and 338 caught on big, the 458 is still in use, but the 264 is all but gone.
