well if you want a 30cal. short magnum..
i would go with the 300WSM. just because there are alot more people buying th 300WSM's and they will last alot longer than the 300SAUM.
if you have alot of 30 calibers. what about the 270WSM? or wait till 2003 to see if they come out with the 35WSM and the 6.5WSM?
