I'll concede a fixed power scope is going to be tougher, but for most people shooting rifles with under 20-25 ft lbs of recoil the difference is probably pretty small as long as decent quality scopes are bought.
The 325 WSM I just don't get and I think Petzal nailed it. He never said it won't work, just that there are much better options.
There isn't enough difference in bullet diameter over the 30's to matter on game, but just enough to have BC's that really suck.
At 500 yards the best 200 gr 308 loads will just about equal the 325 WSM with 200's. Any of the 300 mags or even 30-06 will easily beat 325 WSM with the same or less recoil.
