I'm pretty much hooked on the 8mm's. My 325 WSM is also a Browning Crossbolt - actually, among of the first out. Recoil is a bit stiffer than I like, but it is manageable. Factory loaded Accubonds have done an impressive number on hogs and deer.
Working up some loads for this rifle is among my first reloading projects this spring.
While bullet selection isn't the greatest, there are higher weight bullets - like Sierra's 220 gr Gameking and Woodleigh's 220 gr PP SN for the 325 WSM. If I were shooting 400-500 yds (which most hunters really don't regularly do), I'd choose one of these bullets - matching BC's with BC's. There, I think the 325 WSM will hold its own.
Personally, I'd like to see some good spitzers in the 250-280 gr range for the 8mm's...
