I could see the accuracy advantage if there really is any, if you are benchrest shooting where a 1/32 of an inch difference in a group would make a difference.However if you are talking hunting rifles what would be the big deal about maybe a 3/8 inch group with the WSM or a 1/2 inch group with the Standard 300 Win Mag? The 300 Win Mag is capable of terrific accuracy. In fact its the norm rather that the exception. Again I have no problem with the WSM cartridges but as to any real advantage, to me it just is not there. I don't think the 325 is going to make a splash at all. A few people like I used to be, who have to try everything may give it a whirl but I can see no advantage that is would offer over the 338. Win Mag. I think it will go the way of the 8MM Rem mag. IMO.
