Good discussion....
I believe the 300 WSM to be the practical choice.
The .325 is a little more powerful than the .300 WSM, and has a little more bullet. The SD and BC of the .30's is generally superior, though I have found the 200-gn Partition and especially Accubond to fly PLENTY flat.
There's no wrong choice; the 300 WSM is more practical while the .325 WSM is more... I dunno... fun?
