With an 06 already the 338wm would be my choice. While the 325 is upto the task and would offer nice spacingthe track record for 8mm cartridges being accepted in NA makesone wonder about its survival. Also Ihave wondered what the .323 bullet really offers over a 308 bullet chucked from a 300 wm, wby or RUM...seems to be slight and that just might be why they haven't caught here yet!!
