I tried the 165gr in my300wsm and the best group I got was about 7". I've read alot of good stuff on them ballistically and their game taking abillity but they wouldn't work in my gun for nothing. I switched to some winchester premiers and started getting nickle and dime size groupings. See the Model 70 300wsm accuracy thread. I just posted on it last night so it shouldn't be far down. You can see my fusion shots and my winchester shots. If you do try them hope that you have better luck with them.
