Nothing against the .325WSM but like a lot of other cartridges it has just never excited me, either.
Short action = good if it delivers on the promise of lighter weight. (Otherwise what's the point?)
(Not so good IMHO if it means seating bullets below the case neck - a personal preference thing.)
Fat bullet = good
Ballistic Coefficients = good
Factory ammo costs = high (Like most factory ammo these days.)
Factory ammo variety = low
(midwayusa.com count: 7mmRM = 69, .300WM = 89, .325WSM = 10, .338WM = 35)
Brass availability = low
(midwayusa.com vendor count: 7mmRM = 6, .300WM = 6, .325WSM = 2, .338WM = 6)
Bullet selection = low but adequate
(Midwayusa.com bullet selection: 7mm = 110, .308" = 265, 8mm = 32, .338" = 79)
Again, I'm not knocking the .325WSM, just doubt that with I'll ever own one. On the other hand, if I find a nice one at a screamer price, all bets are off.
YMMV
