Would add, I personally can see no reason for using a 180 in the 8mm WSM. Seems to me the point of an 8mm is to do something a 30 cal is less suited to, and that would mean a 200 - 220 grainer.
Right now my 300 WSM is pushing 200 partitions at 2,850 and I'm running 180's a 3,020 and 165's at 3,150... again, that's certainly far more than +P...
Just the way I see it.
I personaly like the idea of 140's in my 270wsm 165's in my 300wsm and 180's in the 325wsm. Thats just my combo that fits me.
I have done more killing with the 180's in the 325wsm than the other wsm's. It works good! One of the killes with the 325wsm (MY BUDDY's KILL MY RIFLE) was at about 200yds shooting 180gr TSX at a nice bull caribou. The shot was in the right front shoulder and pass threw the left hind quarter. DRT.... Its good stuff.......
