The 325 WSM is a small step down from the 300 WSM and I've yet to figure out why it exists. It is easy to see why it is dying. With the best loads 300 WSM shoots the same bullet weights to exactly the same speeds. You get exactly the same muzzle energy with only .017" greater bullet diameter.
But the same bullet weights in .308 offer much better BC's than in .325 diameter. At as little as 50-100 yards a 200 gr 300 WSM is much better than a 200 gr .325 bullet
