I have a Winchester Featherweight in 325 WSM that shoots 200 grain Nosler Partitions into 0.5 inch consistently with several different powders. It has harvested moose and elk so far with the 200 grain Partition and done so with authority. It shoots 220 grain Sierra BT into sub-MOA groups, as it does with 220 grain Swift AF, 200 grain TSX and 200 grain XLC. I have not worked up a load with the 180 grain TSX as my 300 WSM shoots a 180 grain quite well.
I think the calibre is a winner. Is it better than a 300 WSM? Probably not, but it is another calibre with which to play. It does offer more frontal section on big game, but that is probably not significant. It does not necessarily offer more velocity than you will obtain with similar weight bullets in .308, neither is the SD or BC sufficient to merit jettisoning the 300 for the 325. Ultimately, it is simply a new calibre with which to harvest game.
