I shot my 7-300wsm against Joe Fairley's 7 Max at V2 in June, we were both shooting 184s and our 2 rifles held a combined SD of 5 in our first match. That max is a great setup and Joe is an elite shooter (he beat me by the way and finished 3rd, but it was pretty darn close). I love the big 7s, but I think there's a lot of misinformation about trends in F-class. The 7s are more popular, but out of the 32 invited shooters, at least 6 were running 300wsms. If the Berger 215 hybrid was more available, you'd see twice that.
