Not exactly sure what you're asking, but I'll try. Between the 300 wsm and 325 wsm, I'd choose the 300. As far as accuracy goes, it's a Savage... so yeah, it's accurate.
In the 4 cartridges it comes in I would buy the 338 as first choice and the 300 Winchester as second. I would not buy a WSM, as I wouldn't want to deal with it feeding.
I have owned 2 WSM rifles before one Browning A-Bolt one Winchester M70. Neither fed from the factory even after fighting with them. A friend owns a Kimber 84 in 300 WSM it feeds moderatly well.
